I want to get a handle of a thread of other process in the Win9x.
but th API OpenThread() only can work in Win2K or later.
The best I've managed to do so far is:
DebugActiveProcess()
while( WaitForDebugEvent(&debug_event, ...))
{
....
ContinueDebugEvent()
}
Which will enumerate every thread in a process, filling a DEBUG_EVENT
structure with each thread's handle.
This works, but it's not the prettiest way to do it.
It also has the very unfortunate side-effect of attaching the process as a
child of this one.
What should I do  ? Please help me , Thanks a lot!

Interesting.
As far as I know, you cannot get a handle to a thread from another process because of security reason. The only way is if you spawn the process via CreateProcess(), etc.

I met a problem in MFC extension dll creation and I write to seek your kind assistance.
I created two project: Main.dsw and server.dsw ;
[1] In Server.dsw, I defined a series of classes, derived from CObject, and implemented them with serrialization support;
[2] In Main.dsw, in the document class, I defined a TypedList like this:
typedef CTypedPtrList<coblist, cobject*=""> CActor;
void CXXXDoc::Serialize(CArchive& ar)
{
Actor.Serialize (ar);
}
I then added some objects in this document, all these objects are instances from Server classes;
The problem is, every time I save the document, and then reopen the saved document, a "Unexpected file format" error pops up.
I debugged into the code, and found that it occurs in CObList.Serialize();
However, if I do not encapsulate the classes into server.dll, instead, I directly use them in Main.dsw (I put the source code in main.dsw ), the serialization is ok. This is so strange. Can anyone give me some hints on this?
I have been working on this for half a month, and searched MSDN for quite a few days, will you pls give me a hand?
Your kind help is highly appreciated.

How about GetSystemMetrics(SM_MOUSEPRESENT)?

Hi there.
I'm having a problem with a project i'm currently working on.
I'm writing an MFC extension dll to simplify the reusability of code that i've written. The Project itself is called "STHDll" and i added all necessary
files to it. It currently has the two standard configurations (DEBUG and RELEASE).
In the Project's linker tab i use the following command line:
(Release)
/nologo /subsystem:windows /dll /machine:I386 /out:"../bin/STHLib.dll" /implib:"../lib/STHLib.lib"
(Debug)
/nologo /subsystem:windows /dll /machine:I386 /out:"../bin/STHLibD.dll" /implib:"../lib/STHLibD.lib"
Now if i compile it the linker gives a warning: LNK4070
STHLibD.exp : warning LNK4070: /OUT:STHDll.dll filename directive in .EXP differs from output filename "../Bin/STHLibD.dll"; ignoring directive
Now if i open the .exp file i only find references for "STHDll.dll".
Teh same is for the .lib file.
Can anybody help me with this problem, so that i can create the proper .exp
and .lib files?
Many Thanks.

hi,
After I installed the latest PSDK ,
When I try to compile I get the message '...\rc.exe This program expects a newer version of windows'.
I am running ME.
what could be wrong with the resource compiler?
I am using VC6 SP5 , with latest platform SDK.
regards
Hari

I have this same environment at home and have no troubles compiling (this is in contrast to Michael's comment about Microsoft disabling the product). Perhaps you need to reinstall SP5 with the thought that it might provide the "correct" resource compiler.
What happens if you run the resource compiler from a command prompt? Change to the C:\Program Files\Microsoft Visual Studio\Common\MSDev98\Bin folder, type rc, and see if it gives you the "...\rc.exe This program expects..." or the RC1107 message.

hi,
NOP, the same message. I copied rc.exe and rcdll.dll from visual stidio 6 to platform sdk/bin. It works ok, but i know it is not right.
Any thoughts ?

MS purposely crippled it so it will not run on 9x/Me.  If you have access to older Platform SDK CDs, go back to around Oct 2001 or so and grab the RC.exe from there.

Hi,
How can I read raws and columns of a .csv file?
I would like to move from one column to the next,, how can I do that ?
Ehsan Behboudi

The raws (rows) of the file can easily be read with CStdioFile::ReadString(). The columns can be handled with AfxExtractSubstring(), or CString::Find(). There's more than one way to skin a cat, however.

how do I use those commands in my code
right now this is how I read my .csv file
ifstream infile(file1);
char temp[500];
infile>>temp;
// so now i want to move to the next row or column, how do I do that with your syntax?
Thanks

Very seldom do I use streams so this might not work, although it should get you close:
istream in;
while (in.eof() == 0)
{
is.getline(temp, sizeof(temp));
}

Define "not working."

Some things that struck me as odd:
float atol;Not sure what you are trying to accomplish here.
int main(int argv, char ** argc)Traditionally, argc is the number of arguments, while argv is the argument vector.
if( XOR(argc[1],(unsigned int)atol(argc[2]) ) )
int XOR(char * filename, unsigned long key)In the call to XOR(), the second argument is being cast to an unsigned int, while the function's prototype is expecting an unsigned long.

How can I use the AlphaBlend()GDI function on a GDI Rectange() function on the screen to make it transparent. Is there some sample code to do this?
Thanks

Search for AlphaBlend or Transparent at codeproject. There are articles, FAQ, and totorials that cover this subject.
Good Luck!

Hi,
In my code, i read the system date with the following code,
SYSTEMTIME systime;
GetLocalTime ( &systime );
WORD day = systime.wDay;
WORD month = systime.wMonth;
WORD year = systime.wYear;
now, I would like to store it in this format, day/month/year as CString,.
how can I do that?
Ehsan Behboudi
|
|
|
|
|
CString strDate;
strData.Format(...); // works like printf
INTP
|
|
|
|
|
WORD day = systime.wDay;
WORD month = systime.wMonth;
WORD year = systime.wYear;
CString strDate;
strDate.Format("%u/%u/%u", year, month, day);
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do?? 
(doesn't work on NT)

In the MFC try CTime::Format or strftime for Win32

I agree with the previous poster. If you are using MFC either use CTime or COleDateTime and they both have a function to convert the time to a string in whatever format you need.

Hi !
We are developping an application in C++ with Visual Studio 6 SP5.
I'm compiling my application in Debug mode.
Since a few hours, when I run (with CTRL+F5) my application, it crashes. I have no idea why.
When I try to debug, and run it with F5 (debug), my application does not crash !
Doing some tests, I realised that showing a dummy message box at a certain point in my code make it work !
And, if I compile my application in release mode, it works fine !
My collegue, who is working on the same application doesn't have this problem. If I try to copy his sources directory in my own directory and to rebuild my app, I still have the problem.....
Any idea what's going on ????
Thanks !

Where? Is it at a certain point when you are interacting with it? Does it happen before a particular dialog is displayed? Define "crashes." Is this an unhandled exception? Does it also happen when ran from outside of the IDE?

No, but this article might help.
