Thanks KarstenK, I will try your solution. Vote 5 for you.

Thanks Fedrik, it's great. Vote 5.

Thanks --SA, it's great ! My solution is yours. Vote 5.

Thanks Stefan, it's great. My vote is 5 for you and it is the solution which I like.

Thanks. It's great.

Hi SA, can you have an opinion about this problem? Thanks.

Thanks. You can find to help me? Thanks.

Thanks. It's great.

Thanks, I saw: Resource Hacker can change every things of the file. So I think C# can write a soft to do that.

Sorry, I edit my code above! The condition (p_<20) is an example, in fact, it is an expression of p_. So I have to need to calculate pLength. That mean is: I dont know the size of p pointer in fn() function, when this function is finished we know this size (is pLength). You can help me complete this. Thanks.

Thanks you. I want to List to replace for Array and write dll file with C++ then call it from C#.

Sorry, using array is not convenient! Because the array to pass for function is declared the unchanged size. I use List to improve that. What your idea about this? Thanks. It's difficult for me.

Thanks. My vote is 5.

Thanks, my vote is 5 for you.

In fact, I will call this function twice to get pLength and re-allocate memory space for p:

double[] p = new double[2]; // Allocate with temporariness
int pLength = 0;
fn(p, ref pLength); // Get pLength correctly
p = new double[pLength]; // Re-allocate p correctly
fn(p, ref pLength); // Recall to get p.


But this work has loss "twice" with fn() function! I want to call once fn() function.

Thanks in advance.

Thanks. But how to create space of p array in this dll? Hope you help me.

So I have to re-link it when remove it to another location. Thanks for your support.

Thank you. I'm bad in English so my word becomes difficult to understand. My destination is: I have a def file named "ModPeoject.def" contains exported function symbols, I add it to my project (and it is put in folder project, C:\ModProject). In linker configuration commandline I link to this file by using /DEF:"C:\ModProject\ModProject.def". I compile it successfuly. But when I cut (sorry, cut, not copy) that folder "ModProject" to another location of hard disk (D) and open project, recompile - at this time, I see an error:

Error 1 fatal error LNK1104: cannot open file 'C:\ModProject\ModProject.def'

I have re-link /DEF:"D:\ModProject\ModProject.def" then I compile successfuly.

I dont want to re-link above when I cut that folder to any location in hard disk. How to do this? Thanks.

Sorry I dont understand a problem: "Custom properties settings" - where is it? I dont find it in Property page. Hope you help me. Thanks.

Thanks you. It's great!

It's great. Thanks. My vote is 5.

I created the polygon with n points given (x1, y1),...,(xn, yn). I dont know any algorithm to check if the polygon is intersected or not intersected itself.

Thanks. GDI+ with VB6 is a difficult problem. I'll try to do it. My vote is 5 for you.

Thanks. My vote is 5 for your answer.

Thanks you! It's great advice, I am trying to do this. My vote is 5.

Thanks, my solution is yours.

Thanks you!

Oh, I'm absent-minded! Thanks. It's done. +5 to you!

Hj, thank you very much! It's great!

Thanks. It's very good! I'll applicate for my app.

OK, it's great! My vote is 5. Thanks.

Oh, thanks. When return type of function is user-define type (e.g: A_type,...) how can I solve it? Hope you help me!

OK SA.

Thanks. My vote is 5. I found out that book, it's really great.

Thanks SA, it's great. My vote is 5 for you.

Thanks SA, I will think more about this. I know it's very difficult.

Yes Bill, I am working with Windows Forms, I tried to do as follows you supported, but It did not work; I had to use '\n' to separate the text of menu item and it worked, but I had to manual with code. I want to separate automatically! Hope you help me to do this. Thanks.

Thank a lot for your answer, I've understood it.

Oh, "Condition" is logical expression, can you compare an integer with a logical expression?

I want to display a message box as I ask above. I think you can help me do that. OK? Thanks.

OK, thanks. How to solve this? You can help me?

Oh, I tryed doing as follow your support, e.g:
MessageBox(NULL,(LPCWSTR)L"I love Vietnam",(LPCWSTR)L"Report...",MB_OK);
But it doesnt work! What is happened? Thanks.

Thank you very much CPallini, how to check return value of that function?

Thanks my countryman, I used AfxMessageBox() to instead of MessageBox(), but I can not know how to do that, I think the AfxMessageBox() is only used in MFC, do you agree with me about this? If I am wrong you can help me solve this, thanks.

Thanks, I used Depends.exe to check export of that function, it's exported. I have done follow what you supported, but it doesnt work! Hope that I have another solution of you. Thanks.

Thanks you, I dont have any code, so my question is "how to". Can you support to me that? I will code it when I get ideas from you about this. Thanks.

Oh, I only compiled a Win32Dll which contains bitmaps (like Shell32.dll) successfuly (with C++), I want to "get those bitmaps and display them on PictureBoxes in C#". Hope you understand my those ideas. How to get those bitmaps from that dll and display them on PictureBoxes (control) in C#? (My English is very bad, so I cant say more about this, thanks).

I want to put the bitmaps into a Win32Dll (by C++ - I have done it successfuly), after that I want to get them from my dll and display them on my PictureBoxes (in C#). Can you help me to do this? Thanks.

I'm sorry, I don't understand about what you say. You can give me an example? Thanks.

I updated my post, hope you help me. I biuld well, but when I analyze with "Run code analysis on "a"" and I get the warnings above.

My code was fixed as follows:
- Allocate:
for (int i=0;i<5;i++)
{
f[i]= new int*[6];
for (int j=0;j<6;j++)
f[i][j]= new int[7];
}
- Free:
for (int i=0;i<5;i++)
{
delete[] f[i];
for (int j=0;j<6;j++)
delete[] f[i][j];
}

And I get two warnings (the name of my project is "a"):
Warning 1 warning C6211: Leaking memory 'f[0]' due to an exception. Consider using a local catch block to clean up memory: Lines: 9, 10, 12, 13, 14 c:\users\peter\desktop\a\a\a.cpp 12 a

Warning 2 warning C6211: Leaking memory 'f[0][8]' due to an exception. Consider using a local catch block to clean up memory: Lines: 9, 10, 12, 13, 14, 13, 14, 13, 14, 13, 10, 12 c:\users\peter\desktop\a\a\a.cpp 14 a

I dont understand them. Can you help me check it. Thanks.

I have two problems:
- I allocate it truly or wrong?
- I free it wrong, how to do it truly? I want to understand it well. Please explain it clearly. Thanks.

My vote is 5 for your answer, it's great with me.

Thanks SA, I improved my question.

Yes Sir, but I get memory leak when I do it:
- Allocate them:
for (int i=0;i<5;i++)
{
*f[i]= new int*[6];
for (int j=0;j<6;j++)
f[i][j]= new int[7];
}
And free them as follows:
for (i=0;i<6;i++)
delete[] *f[i];

Please help me solve this, thanks.

My platform is Windows. Thanks.

Yes sir, it's great. Thank you very much.

Thanks, your code is used for MFC?

Thanks SA for your question, I code "Console" platform. Hope you help me.

Thanks, my vote is 5 for you!

Thank you very much, i will see it. My vote is 5. Have a good day!

Thanks you, but it is raw topic, it's not topic which i need. Can you find another to help me, thanks.

My vote is 5.

It's Windows Forms, thanks.

Thanks SA, it's great and i've found out my solution.

Thanks for you answer, it's great idea to me solve my code. My vote is 5.

Thanks, i solved! My vote is 5 for you.

Yes!

Thanks SA, i will try to do it. My vote is 5.

Thanks. I dont understand Collection from your link, i have a declare in VB6 as following:

Private z_Funk As Collection 'hWnd/thunk-address collection

I want to convert Collection type above to C# code, help me convert completely this code. Thank you very much.

Thanks you, Kuthuparakkal. What are "Collection, StdPicture and FormWindowStateConstants" in C#? Can you help me about this? My vote is 5.

Yes, thanks you. It's great code. My vote is 5 for you. Kuthuparakkal gave me a solution above, although i accept your answer which is a solution which i need. Have fun!

Thanks you, it works well. My vote is 5.

Yes, i forgot about that, thanks.

Thank you very much, it works well. My vote is 5 for you.

Thanks you, it works well!

Thanks you, it's great idea.

Thank you, SA. I read it, but i dont get images from C# dll (class library of C#), my dll is WIN32 dll (e.g: Shell32.dll,....). That topic (in your link) uses C# dll. I can convert all VB6 code above to C# code but the third parameter of OleCreatePictureIndirect() (it is "IPic As IPicture") - my main question is "What type of C# does equivalent with IPicture in VB6?". Thanks. My vote is 5 for your answer, hope you help me more.

What is prototype of yahoo_login() function?

Thanks SA, I want to get images from dll file, this is VB6 article:

http://www.codeproject.com/Articles/6953/Loading-Bitmap-pictures-from-external-DLL-on-VB-6?

In this article I see him use OleCreatePictureIndirect() API, i want to convert that code to C# code; i cant find any information about this API with C#. Could you help me? Thank you very much.

Where is the progressbar? If it is in main form (not "another form") - you can use a Timer control to control that progressbar.

My vote is 5 for you.

Thank you.

I dowloaded and installed it, i loaded dll file and saw all C# code. But I couldnt decompile it to source code, how to do this? Thanks.

I'm done. Thanks.

Thanks Kuthuparakkal, I'll try to use it, my vote is 5 for you. Thanks.

Thanks you, it's great, i'll try.

Oh, you can show me that? Thanks.

Thank you very much, I searched it on this site - but not found what i wanted. VB6 is different C# - i know that, but I want to create jcForm with C#, do you help me? Can you translate VB6 code into C# code? Thanks.

Thank you very much, I'm done it. My vote is 5 for you.

I think this is ActiveX dll... so not use LoadLibrary() function.

You can see my answer below.

What do you use WndProcC() function to do?

Only edit hours and seconds? Not edit miliseconds?

Thank you very much. I voted 5 for your answer.

You change it in ForeColor property.

Very good, vote 5.

You should search it, when you understand the usage of it you will solve yourself. Thanks.

I vote 5 for you, it's great solution.

Thanks you, Marcus.

Oh, i dont understand why i can have "Improve solution" with every post?

Oh, sorry you, Jochen. I think you are topic author, now i see topic author is Sharath2790. Sorry you. Thanks you for your agreeing with me.

You use CreateGraphics() method to create "drawing paper", after that you use DrawLine() of graphics library to draw line on it. Good luck!

Thanks you, if so, you accept my answer as your solution (green button) and vote for me, thanks.

Oh, it's happen when you run your app in debug mode? When you buit the messages didnt display? They are not errors!

You search with words "how to use scanf in C++". Good luck!

Where did you see them in your IDE?

Did you code that dll yourself? Or someone coded it?

Thank you very much, all those errors depend on mscorlib.dll, if i dont use it i cant fix those errors (44 errors). I think my problem is not important, i will do it next time. Thank you very much for your ideas.

See my answer below!

You try to change cin.ignore() into fflush() or sync()?

Thank you. I have found that error. At block:

float[] dashValues = { 5, 2, 5 };
Pen penLuoi = new Pen(Color.Olive, 1);
penLuoi.DashPattern = dashValues;

I removed dashValues and instead it to:

Pen penLuoi = new Pen(Color.Olive, 1.0F);
penLuoi.DashStyle = System.Drawing.Drawing2D.DashStyle.DashDotDot;

It's very good. I solved.

Thank you, but if i remove that clause it'll generate other errors, this is not a method to solve my problem, you try!

When I see the end of that message:


************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitdebugging="true">


When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.


Where do i have to put
<configuration>
<system.windows.forms jitdebugging="true">

in my code?

Thanks.

Thank you very much, my code is so long, with message above I dont know error location in my code (what code line?...), can you show me the code line number which is error? Thanks.

Very good, vote 5.

It is my need! Thank you very much. Vote 5 for you.

Thanks SA, your idea is useful for me.

My vote is 5 for your answer and accept it is a solution!

Yes, i think so.

Yes, that is all i wanted. Thank you very much.

Thanks Wes, i am going to test it.

Thanks you, SA. I'm going to study more about it. Can you comment with my topic: http://www.codeproject.com/Questions/460541/How-to-create-shortcut-using-WIN32API-in-Csharp. Thanks.

Thank you, I'll use it, my vote is 5 for your answer, thanks.

Oh, I used it, but not work!

My code:

[DllImport("abc.dll")]
private static extern long CreateLink(IntPtr lpszPathObj, string lpszPathLink, IntPtr lpszDesc);

public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
String str1 = "C:\\abc.exe";
String str2 = "abccvc";
IntPtr pstr1 = (IntPtr)Marshal.StringToHGlobalAnsi(str1);
IntPtr pstr2 = (IntPtr)Marshal.StringToHGlobalAnsi(str2);
long h = CreateLink(pstr1, Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + "\\abc.lnk", pstr2);
}

Please help me. Thanks.

How will i call that function (in button1_Click() above). Thanks.

What I do have to do now? Thanks.

I have used string, but it didnt display exactly, this is dll code:
HRESULT _stdcall CreateLink(LPCWSTR lpszPathObj, LPCSTR lpszPathLink, LPCWSTR lpszDesc)
{
HRESULT hres;
IShellLink* psl;

// Get a pointer to the IShellLink interface. It is assumed that CoInitialize
// has already been called.
hres = CoCreateInstance(CLSID_ShellLink, NULL, CLSCTX_INPROC_SERVER, IID_IShellLink, (LPVOID*)&psl);
if (SUCCEEDED(hres))
{
IPersistFile* ppf;

// Set the path to the shortcut target and add the description.
psl->SetPath(lpszPathObj);
psl->SetDescription(lpszDesc);

// Query IShellLink for the IPersistFile interface, used for saving the
// shortcut in persistent storage.
hres = psl->QueryInterface(IID_IPersistFile, (LPVOID*)&ppf);

if (SUCCEEDED(hres))
{
WCHAR wsz[MAX_PATH];

// Ensure that the string is Unicode.
MultiByteToWideChar(CP_ACP, 0, lpszPathLink, -1, wsz, MAX_PATH);

// Add code here to check return value from MultiByteWideChar
// for success.

// Save the link by calling IPersistFile::Save.
hres = ppf->Save(wsz, TRUE);
ppf->Release();
}
psl->Release();
}
return hres;
}

This function is used to create a shortcut file, I compiled it to dll successfully, I called it in C# as follows:

[DllImport("abc.dll")]
private static extern long CreateLink(string lpszPathObj, string lpszPathLink, string lpszDesc);

public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
long h=CreateLink("C:\\abc.exe",Environment.GetFolderPath(Environment.SpecialFolder.Desktop)+"\\abc.lnk","asdada");
}

When I press button, a shortcut file display on Desktop, but it doent path to abc.exe; when I show the Properties of this shortcut file I receive at Target field: C:\Users\Peter\Desktop\㩃呜䅒啃䑕乁攮數; it contains Chinese string, why? Hope you help me. Thanks.

No, the abc() function is in "xy.dll" which is built by C++ language, I want to call that function from C#.

Thanks you, I have understood my problem when you share your idea, it is very useful for me, your answer is a solution of my problem. Thanks.

Thanks for your idea, it is Windows Form app, I am very very worry about reversing my code. My code is not valuable with everyone, but i want to protect it, i think you should give a method to do this, should not comment on value of my code, it is not important. Thanks.

Use LinkedLabel? When I code LinkClick() event of LinkLabel:

private void linkLabel1_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
System.Diagnostics.Process.Start("mailto:hsacb@yahoo.com");
}
When I run and click to LinkLabel then google mail displays to reqiure log-in google account. You try to know it? Not send email. Another idea? Thanks.
(I want to send email with a subject and a body to me, not log-in any user account).

It's very very cool also, i knew that when I used Visual Studio to code. But I want to have an external application which can be done this, and Kuthuparakkal's idea is useful for me. Thank you very much for your idea. Hope you help me in another problems. My vote for your answer is modest - 5. Thank you again. Have fun!

Accepted! Thanks you.

Thanks you. I like it. My vote is 5 for your idea.

Thank you very much, that's right. I want to protect my code, perhaps obfuscation is the best method to do this. I'm going to find it.

It is great idea which I need, thanks. My vote is 5.

Thank you, I want to create a custom Title bar control, your idea is useful for me. My vote is 5 for your answer.

My vote is 5. Thanks.

Thank you, it is great code. I have found out another solution:

private void DrawFunction(System.Drawing.Printing.PrintPageEventArgs e)
{
// Draw shapes etc...
}

"e" parameter is got from Paint event of the control. Thank you very much.

My vote is 5. Thank you very much.

My vote for your answer is 5.

OK, thank you, it is great idea which I need.

I don't get expected result when I do as your way, I want to use Label to instead TextBox, but Right-Aligned is not to work with Label control, and it works with TextBox control, I need Right align. Another your way to help me do this? Thanks.

Oh, I find error:

public string BsungX
{
get
{
return BsungX; // This error: tmpBsungX, not BsungX
}
set
{
tmpBsungX = value;
txtBsungX.Text = tmpBsungX;
Invalidate();
}
}

Thanks SA.

Thank you very much for your advice, i put

if (!DesignMode) {


}

into my usercontrol methods, but VS still crashes. I very very confuse about this. I used to use Visual Basic 6.0 to work my projects, but now I use VS2008 (VC#) to do this, I only begin learning C#, if you can you help me re-write this code. I hope I will be learnt more C# language from you. Thanks.

When text width is larger than Label width then superfluous text doesn't display, you can try this! Another solution? Thanks.

Thank you very much for your answer, if I change AutoSize property into false then the Label is multi-lines, but i want it is not multi-lines. How to do this? Thanks.

Ok, thank you, I accept it, but I forget to press that button,... Done! Thanks.

Thank you very much, your advice is very useful for me. I will do this, have fun!

Thanks SA, in your opinion what control I should use to draw graphics on? Panel control?

Thanks you. It's my need. My vote is 5 for your answer.

Thanks SA, I have read it but I have not understood more about "delegate", this is a small example that I practise "delegate", so please help me understand it clearly.

Thanks, but I dont find it.

Thanks. It's very good. I resolved. Vote 5.

Thanks, Vote 5.

Hi SAKryukov, I use Win7 and VC++6.0 to code. What the way to do this? Thanks.

Hi DaveAuld, thank you for your comment. But you dont tell me why I still use VB6, nowadays VB6 is not used much to create app, but with small app then VB6 is useful, Im doing my project with this language, in my opinion, you should help me do this problem above, thank you, hope you help me continue.

Thanks, my 5 for your post.

My 5. Thanks.

Thanks, voted.

Thanks. My vote is 5.

Thank enhzflep, I was resolved. My 5.

Thank Christian Graus, I know that VB6 is very old in these days, but Im developing my project in VB6 language, thank you for your advice. Ahm, I need a component to do this, if you have source code then it's very good with me. Hope you help me. Thanks.

Yes, thanks.

Hi Prerak, thank you for your link, but it's difficult with me to do my problem, can you help me use that class to zoom (in and out) picture?

Thank SA, I processed it. My 5.

Thanks. Vote 5.

VB6 not use that code. However I thank you for your code.

Thank you for your reply, I use MSWord 2003 so not have that function, I'll copy it to Excel to do this as your support, my vote to your answer is 5. Hope others help me more!
