Hi all,
I want to know if it is possible to draw some text on top of another object (in my case, it's an MCI movie player)
Thanks a lot.

Yes it is,
if you look in the platform sdk samples there is an MCI video editing example
which allows you to draw hotspots on the video. They draw the lines at the
same place you want to draw your text. I can't remember the example name,
but the example is there.

Would anyone happen to know of any example code for CBT hooks? I've looked at MSDN and I was unable to find some examples.

My program works in the background and controls the foreground window, and it pops out a small dialog to tell the user what it is going to do, and then the dialog may disappear in a few seconds. What can I do to make the dialog to pop out without a focus on it? I mean, what can I do so that the focus won't turn to this small dialog even when it pops up?
Thank you!

Does anyone know of a good Xaudio tutorial or sample code that uses the library? Any help would be great.

I have a large application that loads over 60 of my dlls. I'm trying to increase the load time of the app by re-basing where the dlls are initially put into memory. I think I can hard code the memory address in the dll's settings, or I can use the LoadLibrary function.
My first question is how do you put in the base address in the LoadLibrary function?
My second question is will re-basing all these large dlls really make a big difference in loadup time.
Thank you very much for your help.

You can test whether load times will decrease (I hope you meant decrease, not increase  ) by putting your DLLs in one directory and running:
rebase -b 1000000 *.dll

Hi,
I use a Html Compile file (.chm) instead of hlp file in my Visual C++ 6.0 app.
To launch this file i have a button which call ShelExecute function like this :
ShellExecute(m_hWnd, "open","c:\\Myproject\\MyFile.chm", NULL, NULL, SW_SHOWNORMAL);
It work.
If i press F1 Key i want to launch my chm file, but Winhelp try to run
"c:\\Myproject\\MyFile.hlp". This file don't exist.
To avoid this i override CWinApp::winhelp event in order to use Html Help API instead of
Winhelp like this :
----------------------------------------------------------------------------------
#include "htmlhelp.h"
#pragma comment(lib,"htmlhelp.lib ")
void CNetSenderDlg::WinHelp(DWORD dwData, UINT nCmd)
{
// TODO: Add your specialized code here and/or call the base class
if (nCmd==HELP_CONTEXT)
HtmlHelp(m_hWnd,"c:\\Myproject\\MyFile.chm",HH_DISPLAY_TOPIC,0);
CDialog::WinHelp(dwData, nCmd);
}
----------------------------------------------------------------------------------
BUT IT DON'T WORK. My App try always to launch MyFile.hlp
Can anybody help me to solve this problem
Best regards

You might try overriding CWinApp::OnHelp.
You may have to change the afx message map entry in the App class from ON_COMMAND(ID_HELP, CWinApp::OnHelp) to ON_COMMAND(ID_HELP, OnHelp).

Hi Folks,
I have an ATL COM Server(dll) with one simple object in it. On calling some method Meth() on that object, I want to display a wizard implemented with cpropertysheetex and cpropertypageex.
However when I call the cpropertysheetex::DoModal(), it fails to display. (Trace says 'Property Sheet Failed'). It looks like some problem with the parent window. (I have more or less used the Wizard97 example).
Please treat this as urgent!! I am stuck!!
Thanks,
Girish

Step thru DoModal() in the debugger until you see where the trace message is being printed. You should be able to tell from the immediately preceding code what exactly is failing.

Can someon help me to convert a UNICODE string to ANSI. ( a wchar[] to unisgned char.
TIA.
Anil.

You want the WideCharToMultiByte() and MultiByteToWideChar() functions in the PSDK. The PSDK and MSDN documentation is pretty straightforward.

Check out my Intro to COM article - I discuss methods for converting between ANSI and Unicode.

Hi Anil,
The funcitons mbstowcs and wcstombs are documented in MSDN and do exactly
the conversion you are asking about. However when you are implementing
a system that has both chars and wchars you find yourself doing conversions
all over the place just so you can do things like strcmp.
[And instancinting tempory string objects is even worse]
So try the follow code segment to give you the string functions you want.
You will be able to use the function safe_strncpy to copy from either wchar
to char, char to wchar, char to char and wchar to wchar!
I have found this particularly useful for gradually changing chars to wchars
in a project as the other version of the function automatically steps in.
One day I'll write it up to post to CodeProject.
Jules
--- Code begins here, sorry if the format gets broken along the way ----
** Change of plan - the message was too long!
The function header is
template<class s1,="" class="" s2="">
int safe_strncpy(S1* szDest, const S2* szSrc, unsigned int iLen);
template<class s1,="" class="" s2="">
int safe_strncmp(const S1* szA, const S2* szB, int iLen=-1);
template<class s1="">
int safe_strlen(const S1* szString);
template<class s1,="" class="" s2="">
const S1* safe_strstr(const S1* sz1, const S2* sz2);
and you just use either char or wchar to do the work.
Tell me if you are interested and I'll email the FULL template to you.

I have been using Visual C++ for my development. But two weeks ago, I found that my Visual C++ (MSDEV.EXE) could not be launched. It gaves me runtime error "Abnormal Program Termination for MSDEV.EXE". I have tried several times to uninstall and reinstall the program but to no avail.
I have even reformatted the harddisk, install the Win2000 Pro SP1 (previously I used NT4.0 SP4), then, install VS6.0. And the same error occurred when I start MSDEV.EXE. Others programs like VB or VID run smoothly.
When I install VS6 SP4, it gives me this error:
cannot load package 'devied' ....
Can anyone help me please
|
|
|

When you say you reformatted your hard disk, I assume you mean that you reformatted a second drive that had Visual Studio on it...
In that case you probably have mangled some sort of registry or system DLL... Sometimes thats hard to recover no matter how many service packs you install. I'd go to Microsoft and download their program regclean and give that a go and try reinstalling.
|
|
|
|
|
Nop! My VS6 and NT4 are reside at the same harddisk. When I reformat my harddisk, that means I have clear the NT4 and VS6 at the same time. However, I do have the second harddisk, that is mainly to store my personal data. May be this harddisk contains some registry information? 
I did run the regclean, but the problem still happen.

By chance do you have Numega's Boundschecker installed? Also, please give the exact error messages as you get them.
|
|
|
|
|
Yes! I remember that I have installed an evaluation copy of Numega BoundChecker. Can you give me clue on how to solve this problem? Or may be there are some helps at Numega website?
The exact error when I run the first installed VS6:
Microsoft Visual C++ Runtime Library:
Runtime Error!
Program: ...\MSDEV98\Bin\MSDEV.EXE
Abnormal Program Termination
After I install the VS6SP4, and run the program, it pop up this message:
Microsoft Visual C++
Cannot load package 'devbied' because its internal version number, or the internal version number of one of its components, does not match the version of the Developer Studio shell.
Do you want to continue?
and when I press the only button 'OK', another message box:
Micosoft Visual C++
DEVBIED
This required file cannot be loaded.
Please re-install Microsoft Visual C++
Thanks!

For the error that occurred when I first install the VS6, I have found a way to solve it. It is actually the problem of MFC42.DLL. The MFC42.DLL resides on WINNT\System32\ is not compatible with VS6. To solve it, I copy the MFC42.DLL from the VS6 installation CD, and paste it at the same folder as for MSDEV.EXE. 
However, when I install the VS6SP4, then problems remains. It cannot load 'devbied' package because of different internal version... can anyone help me, please? 
Thanks!

Finally I have solve the problem that bother me for several weeks!! @#$*+!@
To solve the problem, I do the following 2 steps:
1. Replace the Common folder in Microsoft Visual Studio with the one in VS6 installation CD.
2. Copy the MFC42.DLL from the VS6 installation CD into the same folder as MSDEV.EXE
voila! That simple!
Thanks!

Try some of the things mentioned in this link (PRB: Resolving DEVBCPX: This required file cannot be loaded Error):

Downloaded VC++ 5.0 projects loaded into my VC++ 6.0 crash on replying yes to the conversion dialog. These projects do not contain MAC targets as noted on the MSDN VC 6.00 bug list.
I first get an access denied to the .dsw file, followed by a sys crash as noted in Norton Antifreeze. Sometimes the conversion will succeed after a few tries.
I have deleted the .ncb, .opt, and dsw file opening only the .dsp file to create the new workspace related files, but the problem still exists.
Any suggestions?
