Even if this does pacify the compiler, I feel the underlying problem still exists. I just created a test program with a class derived from CDaoRecordset, and an Access table having a date/time column. The constructor looked liked yours and I got no assertion. At this point, I would suggest you do the same thing, and then start adding bits and pieces of code until the problem shows up. Make sense?
I apologize if i reply only now, I had problems with internet connection
I just want to ask if you have the same configuration I submit in my first msg, because if I use win 2000 I have no problem!

 Hello, I searched this message board and I did not find anything about changing the color of the scrollbar in my edit box so I decided to ask. In my dialog box I have 4 edit boxes and I want to modify the style of the scrollbar (CSS does this in webdesign). See an example here of CSS scrollbar style modification

Problem Context: I am writing 2 functions in a dll namely "Fun1" and Convert(thread function).
I am creating a thread within a Function "Fun1" which is called from a tool.
The code for this as follows:
Fun1(Long lChannelNos )
{
HANDLE h1;
NumberOfChn(/*declared at file level of long type*/) = (long)lChannelNos ;
LPDWORD dwTh ;
LPVOID data ;
data = (void *)NULL ;
h1= CreateThread(NULL, // default security attributes
0, // use default stack size
Convert, // thread function
data, // argument to thread function
0 , // use default creation flags
dwTh) ; // returns the thread identifier
if(h1 == NULL)
{MessageBox((HWND)hDIAdemWndGet(),"Failed to create thread","Failure
Thread",MB_OK);
return ;
}
CloseHandle(h1);
return ;
}
DWORD WINAPI Convert(LPVOID lpTh)
{
Here I create linked list, dynamically on heap, using pointers to structure of data type given below.
Thus depending on size of "NumberOfChn",(any value between 1 to 200) the memory requirement varies.
For NumberOfChn = 1 the linked list would consume memory of 40503 bytes(40.5Kb).
}
Problem facing:
1) For NumberOfChn = 1 to 10 (any value) I do not get any error after executing function "Fun1". But if I happens to close the tool, the following error is received
Error: Debug assertion failed
Program: c:\Program Files\National Instruments\Diadem 9.1\Diadem.exe
(This is the Tool from which i make call to "Fun1")
File : dbgheap.c
Line:1011
Expression: _CrtIsValidHeapPointer(pUserData)
2) If the value of NumberOfChn goes beyond 15 it gives
MEMORY ACCESS VIOLATION error.
thats all....
waiting for any solution.

Are you using new and delete for this?

What are you expecting this to do? These type of statements can be removed as they do nothing.
There's too much code here to wade through. Have you tried scaling the problem down to something more manageable? A few dozen lines of code is all you'd need to make a linked list that can easily be debugged. After you are certain that you can add to, and delete from, the simplest of lists, only then should you add all of the other code.

Friends,
How can we display "line numbers" in the editor of Visual C++ 6.0 IDE?
In case of VS.NET, the line numbers can be invoked from:
Tools->Options->Text Editor->C/C++->Line numbers
Is it possible with Visual C++ 6.0 ? If yes, then how ? Also please tell me about the "shortcut keys" to display line numbers in case of both Visual C++ 6.0 and Visual C++.NET+

Look in the lower, right corner of the IDE. You will see line and column number.

hmm.. sorry, i think you didn't get the question.
I am not talking about the line number displayed on the lower right corner of IDE along with column number. I want to display each line number in the source code editor of the IDE.
In case of VS.NET, this option can be invoked from:
Tools->Options->Text Editor->C/C++->Line numbers
Just like to know whether it is possible with VC++ 6.0

Maybe it's a language barrier thing, but the line numbers I mentioned are shown in the editor.  They are, however, not on the left of the code which I think is what you are after.

This functionality does not exist with VC++ v6.

From MSDN:
When specifying an explicit RGB color, the COLORREF value has the following hexadecimal form:
<code>0x00bbggrr </code>
The low-order byte contains a value for the relative intensity of red; the second byte contains a value for green;
and the third byte contains a value for blue. The high-order byte must be zero. The maximum value for a single byte is 0xFF.
So just use masks to retrieve the colors:
COLORREF Color = ....;<br />
int BlueValue = Color&0x00FF0000;<br />
int GreenValue = Color&0x0000FF00;<br />
int RedValue = Color&0x000000FF;<br />
<br />

or use the GetRValue, GetGValue, GetBValuefunctions.

True, because I just realized my version was completely bugged  . It works well for the red component but for this other ones, the bits needs to be shifted...

Cedric Moonen wrote: True, because I just realized my version was completely bugged
yeah, you forgot the shifts...
int BlueValue = Color&0x00FF0000 >> 16;
int GreenValue = Color&0x0000FF00 >> 8;
int RedValue = Color&0x000000FF;

oki, but how can I use the GetRValue, GetGValue, GetBValue functions to display the colorref value in a messagebox or an editbox? an example code?
thanks alot

Just use printf:
char szText[255];<br />
printf(szText,"Red value: %i, Blue value: %i, Green value: %i",GetRValue(...),GetBValue(...),GetGValue(...));
Of course, you have to replace the ... by your COLORREF variable
|
|
|
|
|

For the first one, just use COLORREF GetColour(); from the control.
Dude, when you use classes from an article here, first read how to use it (and there is also example source code with the article). If we don't use this control, we don't know how to use. It just took me 30 seconds looking at the text of the article to find how to use it.

don't call me a dude, and I read before I ask, and if it is bothering you then don't answer at all, I don't need your answer, got it dude?

hi!
Noone answerd my question last time so ill try again:
I have a problem with my directsound application.Every time i play my sound and if there is another application playing(e.g windows media player) i get corupted sound.My cooperative level is DSSCL_PRIORITY. I also have problem when trying to create DirecSound object with CoCreateInstance metod(always fails).
If anyone has some experience with this problem or if you can direct me to some good article i would be very grateful
Many thanks!

I have service application which has to launch an application in the context of the current interactive user. If there is not interactive user, then the application will not be started.
I tried using CreateProcessAsUser, but then I need to have a token to that user's session. How do I get that?
Thanks!
