Hi!
I'm new to multithreading and developing in VC++ 6 directly with the win32 API.
In console mode, the usual code to create another thread and use it runs well in my system, but I have no success when using WinMain, like in the very simple code below:
int globalval;
void __cdecl TestThread( void* param ){ globalval=10; }
int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE,
PSTR szCmdLine, int nCmdShow )
{
globalval = 5;
_beginthread( TestThread, 0, (void*)NULL );
CreateMyWindows(hInstance);
MSG mess;
while( GetMessage(&mess,0,0,0) )
{
TranslateMessage( &mess );
DispatchMessage( &mess );
}
return mess.wParam;
}
I go past the _beginthread call and it even returns a thread number, but apparently TestThread doesn't run at all, because globalval doesn't change. Then after the first call to GetMessage I get the error message "R6016 not enough space for thread data".
Yes, I have VC6 with project set for run-time library "Debugging Multithread".
Any ideas?
Thanks a lot,
Rick Trelles

Hi All,
I am trying to show a message box with only one button"Cancel".
int MessageBox( HWND hWnd,
LPCTSTR lpText,
LPCTSTR lpCaption,
UINT uType
);
in uType we can give
MB_OK or MB_OKCANCEL.
But I want to have only one button on messagebox ie "Cancel".
how can I get this.
Thanks
..

Yes but MB_OK is not going to give him Cancel button.

I dont think we have MB_CANCEL but I think he can changes title of button.

After reading MSDN documentation I couldn't find anything. Do you know how to do that?

You can get a handle to a messagebox window and then you can change text of it.
|
|
|
|

MessageBox is a modal window so it blocks the calling thread. So once you call MessageBox then unless you dismiss it nothing else can be done.

I saw my files it was on the C#.

I hate to do this but it is not going to work in C# as well. System.Windows.Forms.MessageBox mimics MessageBox in windows. So there is no option to use just the Cancel button.

Why c# is good I think its easy to learn anyway maybe you like to see Dissecting the MessageBox[^].

I never asked why C# is good!!! We were talking about MessageBox. I have seen that article and it create a new class for doing custom stuff. It has got nothing to do with MessageBox WinAPI provides.

I don't think it is possible with MessabeBox. You can simple create your own dialog and add a single cancel button.

Thanks Guys,

I wanted to try with messagebox only.
Any way thanks for ur replies.

I want to format 3 digit numbers as follows
if number is 6 then add "00" before number; SNumber = 006
if number is 15 then add "0" before number; SNumber = 015
CString givenTEXT;
GetDlgItemText(IDC_ID, givenTEXT);
int TEXTvalue = givenTEXT;
CString tempTEXT;
if (TEXTvalue < 10)
{
tempTEXT="00" + TEXTvalue;
}
else if(TEXTvalue < 100)
{
tempTEXT="0" + TEXTvalue;
}
else
{
tempTEXT = TEXTvalue; //error: "=" operator is ambiguous
}
if i change the last line to
tempTEXT = "" + TEXTvalue;
it compiles but tempTEXT is all screw up : "..\include\Atlexcept.h"

Try this.
int i = 15;
CString str;
str.Format("%03d", i);

I've tried the conversion routines and still get errors. I receive from an edit box a number. I want to add something to that number and then put it into a CString. can someone show me a code example that works Please. I can get the number find but I can't add something to it and then put it back into a CString.

I am sorry, what exactly is the problem? Perhaps some code you tried will help.

For instance : int a = 42; CString str; int tmp;(pEdit already established) pEdit1->GetDlgItemText(str); now str holds the value the User typed which was NOT a number. but the representation of a number in character format. Now tmp = _tstoi(str); WORKS it changes the character to a number and puts it in tmp(an integer). but my question is How do I do the reverse? How to I get an integer valve into the CString(ie str)?
I've tried these functions: _itot_s, _itoa_s, and _itoa and they all give a long error message basically saying the str cannot be transfered to a char*
I know there is something that works, but I can't recall what it is.
I just want to put an integer value into a CString after I have converted one from the User's entry.

Okay I think the problem is _itot excepts second argument to be either wchar_t* or char* depending whether unicode is defined or not and it cannot automatically convert from CString to char* or wchar_t*. I don't use much MFC so not sure if there are function in CString to automatically do this but you can try something like this:
int i = 42;
CString str("50");
int temp = _ttoi(str);
temp += i;
TCHAR buffer[50];
_itot(temp, buffer, 10);
str = buffer;

works until the last statement: str = buffer; at this point buffer does indead have the value I want, but I get an Access violation error when the assignment operator in CString tries to assign buffer's value to the CString(ie str).

check CString format function
CString tmp;
int a = 5;
tmp.Format("%d Hey ", a);
Hope this helps.
