Hello,
I don't think that there is an easy way to remove the close button, since it's part of the system menu. You can use GetSystemMenu() to disable it..
You can also remove the entire title bar.
But please tell me why you want to remove the close button? Users will be really annoyed by this!

Try this: GetSystemMenu(FALSE)->EnableMenuItem(SC_CLOSE, FALSE);

Hi,
I've written a windows service to parse files.It uses the FileSystemWatcher class in C# to sniff a folder for particular type of files. But when the files were being processed, i repeatedly get the error "The process cannot access the file "AAA" because it is being used by another process". To overcome this problem, i added the following. lines of code
<br />
<br />
public bool ParseEnvFile(string strFilePath)<br />
{<br />
try<br />
{<br />
using(FileStream fs = new FileStream(strFilePath, FileMode.Open, FileAccess.Read, FileShare.Read))<br />
{<br />
fs.Close();<br />
m_nReadAttempts = 0;<br />
}<br />
}<br />
catch(IOException ex)<br />
{<br />
if(m_nReadAttempts < 3)<br />
{<br />
Thread.Sleep(2000);<br />
m_nReadAttempts++;<br />
return ParseEnvFile(strFilePath);<br />
}<br />
else<br />
{<br />
throw ex;<br />
}<br />
}<br />
.....<br />
}<br />
But even this did not solve the problem. The exception still kept coming, though less frequently.
So I was forced to add a Timer event(runs every 5 mins) that would pick up all the files that were left over because of the exception.
Now, my problem is this:
When a file gets created in the folder, sometimes both the OnFileCreated event and the timer event try to access the file at the same time. Within my
service, I'm required to open the file in write mode and update some contents. I find that at times the file that gets created ends up as a 0KB file (Note: when it initially got created the file had some content in it)!!!!
Any ideas on why this happens?
Thanks for any help in resolving this problem.

hiho@ll
i'm using Visual Studio .Net
1. i have compiled/runned/debugged many "self-made" projects and some projects from codeproject.com
2. i got the source of a programm which i want to debug, which seems to be programmed using visual studio 6.0
3. if i try to debug the prog i get the following error:
"
Unable to start debugging.
Unable to start program "c:\program files\internet explorer\iexplore.exe"
Das System kann die angegebene Datei nicht finden.
"
4. it seems that .net tries to debug using iexplore.exe in program files folder
but my iexplore.exe is in programme\Internet Explorer\...
question: how can i change the debug options for this project that .Net knows that iexplore.exe is not in program files\ but in programme\ folder?
thx@ll

Where did you paint the bitmap onto the dialog ? You need to do it in either OnEraseBackground, or OnPaint.

Thanks Sir
I am loading Bit Map directly on Dialog and that's why I think problem are coming
"but how i do it on OnPaint?"
Best wishes

Load the Bitmap into a Bitmap as a member variable in the class, override the OnPaint method of the class, and draw it there.

Hi All,
I have developed an MFC application with 2 views & a dialog window,all of which are dockable.So it looks more like when we open our microsoft Vc++ application.
The messaging system was taken care by a collegue of mine,who used "RunModalLoop" function for handling windows messages. Thats why this post.
My dialog window contains a Grid control.When I make a change in one of the cells in the grid & go & hit any of the toolbar buttons or menu items,the after edit event of the grid is not getting called. when I click on any of the views,the afteredit event is getting called,which is what I need.
What could be reason that the "AfterEdit" event is not getting called(when Hit on toolbar buttons & Menu Items).Does this has anything to do with "ModalLoop" calls.
Thanks for any help...

Hi,
My GUI is required to call a code that is a console application. The progress is displayed in the console. My GUI button calls this code fine and data is written correctly. The problem is I don't see the console from the button call and the user has no idea when the routine has completed. Would this be something to do with CreateProcess()? I know that this function can be used to call applications but what about subroutines?
Thanks.

Using CreateProcess() is the correct method. However, I would make the console window hidden, and capture the text that is written to it in my GUI window. See here and here.

I would like to toggle sound in my program via a Menu item.
I have included a Menu option and event as follows, but how can I either set the Menu text 'checked' or change it to read:
Sound On or Sound Off.
void CExampleDlg::OnSystemSound()
{
if(g_bSound)
{
g_bSound = false;
SetDlgItemText(ID_SYSTEM_SOUND, "Sound Off");
}
else
{
g_bSound = true;
SetDlgItemText(ID_SYSTEM_SOUND, "Sound On");
}
}
Where ID_SYSTEM_SOUND is the Menu item. Can you declare a member variable for this Menu item? I saw no options in the Class Wizard.
But the Menu always displays the default text (Sound On); i.e. never changes.

I believe you need to call CWnd::GetMenu(...) which returns a CMenu*. Check out the member functions in that class.

Thanks for your post. Will read the article.
Got code working:-
if(g_bSound)
{
g_bSound = false;
CheckMenuItem(m_MyMenu, ID_SYSTEM_SOUND, MF_UNCHECKED);
}
else
{
g_bSound = true;
CheckMenuItem(m_MyMenu, ID_SYSTEM_SOUND, MF_CHECKED);
}

i wrote this code about the Matrix project here is a part of the code to input the matrix or a vector with a dynamic allocation:
double*vector ; int num ;
cout<<"enter the size of the vector"<<\n;
cin>>num;
vector=new double[num];
for(i=0;i<num;i++)
{
cout<<"enter="" the="" element"<<i+1<<"in="" vector"<<\n;
="" cin="">>*(vector+i)
}
this for input the vector but for input the matrix i made it in another function:
double*grade ; double**matrix ; int row ; int col;
cout<<"enter the number of rows then coloumns in the matrix"<<\n;
cin>>row>>col;
double**matrix=new double*[row];
for(int j=0;j<row;j++)
{
matrix[j]="new" double[col]
="" for(int="" k="0;" k<row;="" k++)
{
="" for(="" int="" l="0;" l<col;="" l++)
{=""
="" cout<<"enter="" the="" element"<<l+1<<"in="" row"<<k+1<<\n;
="" cin="">>*(grade[k]+l)
}}}
iwant to ask of there is any missing in the followin part of the code
second if i want the program to ask the user if he wants to input one or more matrix can i add this :
for(int c=o;c<n;c++) where="" n="" is="" the="" number="" of="" matrices="" user="" want="" to="" input="" i="" put="" all="" previuos="" for="" loops="" in="" this="" loop="" but="" withmall="" change="" as="" folows
in="" stead="" writing="" matrix[j]i="" will="" write
matrix[c][j]="new" double[col]
&="" instead="" cin="">>*(grade[k]+l) i will write
cin>>*(grade[c][k]+l)
so may you answer these previous questions?

Use code tag to format the code,
It is difficult to differentiate between your code and comments!

When you are showing code in your post, use pre tag which you can find above those smileys. That will make your code to appear in paragraphs instead of them hugging to the left as it was with your post.

He means you should format the messages you post for a better readability. By using for instance this format for code extracts or that format to highlight important words. If you don't take care to the format of your message, people will have difficulties to read it or to understand your code, and will simply not answer to the question
