To solve the problem, I thought to load the animated cursor resource and then create the cursor handle with the following code:HRSRC hResInfo = FindResource(NULL, MAKEINTRESOURCE(IDR_HOURGLASS), RT_ANICURSOR);
DWORD dwResSize = SizeofResource(NULL, hResInfo);
HGLOBAL hRes = LoadResource(NULL, hResInfo);
PBYTE pResData = (PBYTE)LockResource(hRes);
HCURSOR hAniCur = CreateIconFromResourceEx(pResData, dwResSize,
FALSE, 0x00030000, 32, 32, LR_DEFAULTCOLOR);
The problem remains 
All the instruction are successful with both types of linkage, but the last returns a valid handle only when dynamically linking to MFC. When I specify to use static MFC libraries, CreateIconFromResourceEx() cease to work and returns NULL.
Can anyone tell me why?
I tried to debug USER32 code, but it's a suicide without debug symbols.
Where can I get debug symbols for Windows 2000?
Please help!!

i'm working on a program that reads an open file and puts a line into a sting buffer until a newline is found, then puts the string into the clipboard. This is done through a windows WH_KEYBOARD hook... is there anyway for the read file's handle to be shared so that all processes can share the same instance of the handle?
Any non-MFC solution would be very much appreciated.

Can I create a MDI form with child forms WITHOUT USING MFC? If it's possible, could you show me some code to do it?
Thanks a lot in advance!

If you really want to do it without any wraper classes (i.e. MFC), get a few books like, "Windows 2000 Programming from the Ground Up" by Herbert Schildt. Herbert likes to hand crank all his stuff and will have examples on how to handle the messaging and window creation.
If you just want less complicated CWnd objects you can create a MDI application without the Document/View Architecture. This gives you the CView without the attached CDocument.
Unless you want to be able to use different compliers to compile your code, I would use window wraper classes for my development. They do make life easier.
Good Luck,
Jonathan Craig

Have you looked in the SDK samples? I would be quite surprised if there are not any samples there. Also I think that the Platform SDK documentation that describes MDI programs would at least have peices of a sample.

YES, you can. It's called WTL (Windows Template Library). It's on the Platform SDK, and it's great. You can create full-featured apps without MFC bloat and no dependencies.

I tried the WideCharToMultiByte function but it seems that I have no success.
I'm trying to write an XML file.

Uwe, here's a UTF for Linux FAQ that talks about decoding UTF-8. It should give you a start regarding going the other way.
Here's a Google search that will give you some more stuff to look at.

Thank you very much, Mike!
I'll post a solution as soon as I figured it out. Maybe it will help others.

After mailing with Markus Kuhn, the author of www.cl.cam.ac.uk/~mgk25/, he told me the following solution (function 1), which I wrapped a little bit (function 2):
static int Latin1toUTF8(TCHAR *t, const TCHAR *s, int len)
{
const TCHAR *p = s;
TCHAR *q = t;
while (p < s + len) {
if ((*p & 0x80) == 0) {
*q++ = *p++;
} else {
*q++ = 0xC0 | ((*p >> 6) & 0x3);
*q++ = 0x80 | (*p & 0x3F);
p++;
}
}
return q - t;
}
void StringToUTF8( const CString& input, CByteArray& output )
{
output.RemoveAll();
if ( input.IsEmpty() )
return;
output.SetSize(input.GetLength()*6);
const int new_length = Latin1toUTF8( (TCHAR*)output.GetData(), input, input.GetLength() );
ASSERT(new_length<=output.GetLength());
output.SetSize(new_length);
}
Thanks to Markus!

Anyone know how I can allow the user to enter a string wider than the edit portion of the CComboBoxEx? I've tried LimitText which works if I set it to a low number like 5. However, if I set it to a high number like 1024 or even 50 it doesn't take. I saw the comment in the MSDN about having to set the style to CBS_AUTOHSCROLL and tried that but still haven't gotten any luck.
TIA,

Has anyone else noticed new problems with VC++ 6 after moving from NT4 to W2K?
I got a new system with W2K and after installing VC++ 6 the IDE now has a few small but very annoying problems that I don't recall from the NT4 days. I haven't yet applied SP4 because of MS' terrible track record with service packs. I thought I'd wait a few months to see if there wer any problems. Anyway, the problems are:
1. Cut and paste of code doesn't always work. You can select the text then hit CTRL-C but the IDE WILL NOT paste it into the new location no matter how many times I try. Repeatedly re-selecting and re-copying doesn't do anything. However, if I change my copy selection just by one character it works just fine!
2. When trying to save a modified source file, which is part of a loaded project, the IDE will tell me that the file cannot be saved (I forget the exact error). But if I try again, almost immediately, the file saves just fine. It's like there are two threads working with the file but they don't have any cooperation.
3. The IDE will periodically crash when I hit F7 to rebuild. This was so rare under NT4 that I was really surprised when it began happening under W2K.
4. After doing a cut/copy or paste the IDE gets stuck in selection mode. That is, the last location of the carat becomes the start of a text selection and wherever you move the carat to becomes the end of the selection. No amount of ESC, CTRL-C or anything will get it out of this selection mode. I got really pissed and wiped my hands over the entire keyboard several times, like you would a piano keys, and the all went back to normal. That is now how I fix it. It sounds like I'm beating the sh*t out of my keyboard !!!

I experienced what you say at point 4, but just one time.
I remember that selecting other text saved me from that trouble.
Never experienced the other points, however, maybe point 2 but one or two times.
I can't say why...
Cheers,
Paolo.

Interesting, I though this was just me...
I am getting 1 very frequently, which is extremly annoying. I usually can't get pasting to work untill I have made a sucessfull paste outside of the IDE. I have absolutely no idea why this is.
I have never experienced 2 or 3, but 4 is also trur for me, though not just after attempting to copy.paste. Sometrimes the selection will just remain untill I reopen the source file.
I alos get another problem though, which is that the IDE VERY frequently stops responding for about 20 - 60 seconds, and then resumes. This is not during compile time, ubut while editing files. I have been told many approaches to solve this, but none have worked. Maybe it is because I have too many include directories set up, and VC++ uses a timer to update intellisense or something?...
Oh yeah, I am also using Windows 2000, the profesional edition, and didn't have these problems with NT4.

Opps, I have very bad spelling which is obvoius from my last reply.
Sorry.

I also encounter IDE pauses frequently but they are usually no longer than 2 or 3 seconds.
You didn't say what kind of system you had, buy my system is a 800 MHz P3 it may be fast enough to make the pause less noticible.
You are probably right about the delays being caused by intellisense. I thought about turning it off until it dawned on me how much I use it

I don't think my system has much to do with it, before the move to Windows 2000, I was using a dual P2 450 with 128 MB RAM (NT4 SP3), but now I have a dual PIII 650 machine, with 512 MB RAM.
I also can't live without intellisense, it would require learning a hell of a lot about MFC that I don't want to, and don't have the time to.

I have experienced (1), (2), and (4) on both NT4.0 SP 6.0a and Win2000 SP1. I have never experienced 3 on either operating system. I was really hoping that DevStudio SP4 would fix (1) because that is the problem I see most frequntly.

You said that you were hoping VCPP SP4 would fix the problem, did it?

Hi Everyone,
How do I get the dialog box of Open & Save to come up?? (like the ones you see when you want to open and save a document in Microsoft Words).
I tried using CFileDialog but I'm having trouble. I'm not sure if I'm putting the wrong things in the parameter or what. I also get this error message of "failed assertion".
If anyone have any codes on an example of how to get the dialog box to work, please let me know.
Thanks in Advance!
Steve

Hi Steve,
That should be pretty simple:
CString filename;
CFileDialog opendlg(TRUE, NULL, NULL, OFN_HIDEREADONLY,
_T("Text files|*.txt;*.doc|Images|*.bmp;*.gif||"));
if (opendlg.DoModal() == IDOK)
filename = opendlg.GetPathName()
This code works for a single selection dialog. At the end you have the complete name of the selected file in the filename variable.
This should help you getting started, but refer to MSDN for a complete explanation.
Cheers,
Paolo.

I am using GetDIBits()
function for a Win NT VC++ application
I need to use it for a Ce application but the function
GetDIBits()
is not available for CE.
So please suggest a replacement function
or an alternative approach
Thanks in advance

I found the article, "A DIBSection wrapper for Win32 and WinCE", at http://codeguru.earthweb.com/ce/DIBSectionCE.shtml
It may help with DIBs under Windows CE.

Where can I get a freeware memory-leak detection tool, like the (more advanced) Boundschecker?
|
|

|

Hi,
I've never heard about free tools like this...
BoundsChecker is a good staff and it worth spending money.
