Using MS Shell Dlg makes the OS use the "Default dialog font", which differs among languages. Setting it to Arial only works if the version of Arial you have on your system contains the DBCS characters. If you get only ||||| then the font doesn't have them.
As a last resort you can always set the font of just the control to SimSun or whatever font you want that can show DBCS chars.

Hi guys,
This is a question on Load Icon in VC 6.
I am giving the code snippet.
This code I have put in OnDraw() function
HICON hicon1;
CDC WordkDC;
HINSTANCE instance;
WorkDC.CreateCompatibleDC(pDC);
instance=AfxGetInstanceHandle();
hicon1=::LoadIcon(instance,MAKEINTRESOURCE(IDI_ICON3));
WorkDC.DrawIcon(100,200,hicon1);
pDC->BitBlt(0,0,1012,668,&WorkDC,0,0,SRCCOPY);
AfxMessageBox("In ondraw if condition");
I am seeing only the MessageBox but not the icon why ??
Instead of the WorkDC if I use pDC I could see the icon.
Can anybody tell what's wrong with my code.
Thanks
Satya

WorkDC is a memory device context - it's not associated with a display device. In order to be able to draw anything in it, it has to be associated with a bitmap for it to draw on. Using pDC works because the device context has somewhere to draw - the screen. To make this section of code work, you'll have to create a bitmap for it:
HICON hicon1;
CDC WordkDC;
HINSTANCE instance;
CBitmap bitmap;
CBitmap *pBitmap;
WorkDC.CreateCompatibleDC(pDC);
bitmap.CreateCompatibleBitmap(pDC, 1012, 668);
pBitmap = WorkDC.SelectObject(&bitmap);
instance=AfxGetInstanceHandle();
hicon1=::LoadIcon(instance,MAKEINTRESOURCE(IDI_ICON3));
WorkDC.DrawIcon(100,200,hicon1);
pDC->BitBlt(0,0,1012,668,&WorkDC,0,0,SRCCOPY);
WorkDC.SelectObject(pBitmap);
bitmap.DeleteObject();
AfxMessageBox("In ondraw if condition");Hope this helps,
Ryan

Thanks Ryan,

You're welcome
BTW, instead of hardcoding the width/height of the bitmap, you might want to use GetClientRect() to get the dimensions of the client area, and specifiy the height and width from that instead.

Hi,
I'm using dtpcustom to specify my own format od date and time display.(yyyy-mm-dd':'dddd)
English (US) is set as default language of my system.when the locale is set to English(US) the date time picker can show the dddd part as "saturday" in english correctly.when i change the locale to Chinese(PRC),some junk characters are displayed instead of displaying "saturday" in chinese.

Hi!~
The problem is:
in VC++, I created a dialog using the dialog editor, and add a CEdit to it.
From the main program, I want to call and DoModal() this dialog. Before I DoModal it, I want to hide the CEdit control. I am doing it like this:
dlg.m_cedit_control.ShowWindow(SW_HIDE);
if (dlg.DoModal()==IDOK)
{
......
};
However, the debug assert at the above ShowWIndow line.
Any one know by which way I can get what I want?
Thanks a lot and have a nice day.
(Actually, the dialog is created for multi purposes. So sometimes, before it is shown, I want to display the CEdit to the user so that user can input. But sometimes, I want to hide it.)

|

You can't call ShowWindow() until the edit control is created, ie. until DoModal() is called. Set a flag in the dialog box, and then show/hide the window in OnInitDialog() in the dialog:
dlg.m_bShowEditControl = FALSE;
dlg.DoModal();
...
CMyDialog::OnInitDialog()
{
...
if(!m_bShowEditControl)
m_cedit_control.ShowWindow(SW_HIDE);
...
}Hope this helps,
Ryan

I created an MFC Extension DLL that when calls checks a file, and condictionally displays a dialog box and quits. It compiled fine.
But
When I went to create a sample app, I added the lib to the project and included the header file from the MFC Extension DLL.. Called teh function:
CPluginMessage mPIM;
mPIM.CheckForInformation("asdf.exe","ASDF","None");
But when I compile the app it throws a fit and says:
--------------------Configuration: asdf - Win32 Release--------------------
Compiling...
asdfDlg.cpp
Linking...
asdfDlg.obj : error LNK2001: unresolved external symbol "public: int __thiscall CPluginMessage::CheckForInformation(class CString,class CString,class CString)" (?CheckForInformation@CPluginMessage@@QAEHVCString@@00@Z)
asdfDlg.obj : error LNK2001: unresolved external symbol "public: __thiscall CPluginMessage::CPluginMessage(class CWnd *)" (??0CPluginMessage@@QAE@PAVCWnd@@@Z)
Release/asdf.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.

Compile the DLL using multithreaded DLL linking.

Where under Project Settings would I find that? I looked but couldn't find it.

Nevermind, I saw where Multithreaded DLL linking was, but thats how its been compiled, and the sample app still puts out the error message (its a new MFC Dialog app (its nothing wrong with the rest of the program).

Did you add the AFX_EXT_CLASS macro to the class declaration in your MFC Extension DLL code?
<code>
class AFX_EXT_CLASS CPluginMessage
{
CPluginMessage();
~CPluginMessage();
}

Hiya I am having a serious problems with this. I have to read in records from a file that are formatted like this example:
"don't,need,this,\r23,this_record_could_be_any_size_1k_or_100k,\r45,don't,need,this,either,\r23,this_record_could_be_any_size_1k_or_100k,\45,don't,need,this,either....and so on.
The start of each record is \r23 and each record ends with \r45...
My problem is that I am using MFC function 'file.Read' to read in a certain amount of data, 1kb. But what if my record was longer than 1k, I would have serious problems.
What I would like to do is read in a certain amount of the data, find the start of the record i.e \r23, set the file pointer to that position and read the file until I find the end of the record i.e \r45.
And then position the file pointer to start looking for the next record.
But I can't get it to work for me at all.
Could someone help me on this plz..very urgent.
Thanks.

I did something almost exactly like this once except my data was not as variable. The format was:
WORD (record id)<br />
WORD (index)<br />
unlimited number of characters up to a \0 character<br />
WORD (record id)<br />
WORD (index)<br />
unlimited number of characters up to a \0 character<br />
WORD (record id)<br />
WORD (index)<br />
unlimited number of characters up to a \0 character<br />
...
So when the file pointer was at the beginning of the characters, I read something like 2,000 characters knowing that I would find the \0 character 99.99% of the time. Taking the difference between the two file positions, I knew the length of the data. I did all this via a memory-mapped file so it was very fast.

Hiya, yes thats exactly what I did e.g
file.Read( buffer,2000 );
But thats my problem. I don't actually know the maximum the record could be. It could be 2k or 200k.
I don't know how to read in a file, searching for a specific string??
Or if I can't do it that way, how could I read in the string and keep checking it for the end of record.
Does anyone know??

Given the variableness of the data, it doesn't appear that CString::Find() will be of any benefit to you. However, you can still use a memory-mapped file so that you only have to access the disk once.
CFile file;
LPBYTE lpBuffer;
CMemFile fileMem;
if (file.Open(...) == TRUE)
{
lpBuffer = new BYTE[file.GetLength()];
file.Read(lpBuffer, file.GetLength());
file.Close();
fileMem.Attach(lpBuffer, file.GetLength());
...
fileMem.Detach();
delete [] lpBuffer;
}

Hi,
What messages do I need to use (if this is the way) to set the position and size of dialog controls if I am not using MFC.
Thanks in advance

Suppose I have a dll containing the implementation of a logging tool.
I also have another dll containing the implementation of an exception class.
Now, I would like any external object INCLUDING an instance of the logging tool to be to throw exceptions using my excpetion class.
I also want the Exception class to log every exception thrown into a log file.
So, the dilemma is two dlls that depened on each other.
Obviously, there are many hackish way of getting around this, but is there a standard and eloquent way of dealing with a situation like this?

I am in desperate need of being able to increase the height of my statusbar in an Doc/View MFC application. I need to owner draw the whole thing as well, but I don't think that is much of a problem. I tried looking into code like CSizingControlBar but I wasn't able to figure out what is relevant and what is not as it is extremely complicated. I would have never thought that something that should be as trivial as resizing a statusbar would be so difficult.
Cheers,
Clint

m_wndStatusBar.GetStatusBarCtrl().SetMinHeight(nMinimumHeight) in CMainFrame::OnCreate() after the status bar has been created.
Hope this helps,

How can I set the key states that GetAsyncKeyState() returns?
SetKeyboardState only sets the ones that the other keyboard functions return, but GetAsyncKeyState() is global it seems.

Hello all,
I want to develop a piece of software in VC++, but I have some questions as Iam a *very* unexperienced VC++ user..
The program has the following requirements :
The software should be able to run in all Windows versions.
When first running the setup, the software must ask me to enter an x number of days.
When windows starts up, it must run in background (as a service), meaning it may not be visible for users nor tracable.
Every time windows starts up, the program should check if the number of days initially configured has not already passed.
If not, nothing should happen.
If the time has expired, the program should ask for a password.. As long as the password is entered incorrectly, Windows access should be blocked (by means of a password popup loop or maybe better, a restart of windows every couple of time the password is entered incorrectly)
If the password is entered correctly, nothing should happen , the program keeps running in the background or uninstalls itself)
It must be relatively secure, meaning a user should not be able to stop running the program..(with the windows taskmanager for example)
My questions are now :
Is this easy to implement using C++ ?
Do you have some tips to share ?
I am basically a web developer, but I have some experience in C++ (unfortunately the borland version) and this is a good opportunity to finally learn Visual C++.. (I used it very long time ago)
Many thanks in advance for your answers !!

Since you are experienced in programing this should be fairly easy for you, except the part where you would want this program to run as a service. Do you have any experience in that?

That depends on what you're trying to build and what kind of functions you will be calling. In general most programs will run in all Windows versions but you should always check the functions that you are using. They always tell you the platforms where they can run. Also from my experience in using ADO 2.7, I found out that I can't install MDAC 2.7 in windows 95.

You could check out this article [^].

This is not difficult either. You have to encrypt your password and store it in a safe location. Make sure it's a one way encryption and don't provide any decrytion methods in your source code. When the user enters the password, encrypt it, and then compare it against the encrypted stored password. You should be able to find many encryption libraries in the web.
konac wrote:
Windows access should be blocked
I really have no advice on this topic because I am so against blocking the user from logging in just because your program decides to do so. Let Windows handle that. No offense.
