Did you use CharMap to see what characters 173 and 175 in the Symbol font set were?"One man's wage rise is another man's price increase." - Harold Wilson

They're not what I want. The characters I want are U+25B2 and U+25BA. They show up in charmap but their codes are not accepted by the compiler. Again the D "_MBCS" flag is set.

Then you have to use the "Wingdings 3" font, characters 112, 113.If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

OK, now I get it. I wasn't sure how changing the font could help. Yes that works. Now I have to hope the users all have Wingdings 3! But that's a problem for another day.
Thanks to all for your help!

I've used such font to show the arrows on the button.
Wasn't that what you were asking for?

I See your Drift, but How do you change two chars in a font ( to say Marlot chars or Bitmaps)leaving all the others the same.

This has been bugging me. What I was thinking of was DrawFrameControl(). Check it out to see if it helps you any. The situation I used it for didn't care about graphic prettiness or themes. I seem to recall that there was some issue in using it where that was important.

Hi,
I have various builds of a DLL, depending on the target platform and I would like to be able to modify the 'Comments' item of the VERSIONINFO structure depending on the build. This would allow me to see which version of the DLL the end user has on their system. (I have had occasions where they have unknowingly copied the wrong DLL for their platform). The DLL name is deliberately identical so that the parent application does not need modification for different platforms (thats the whole idea of the DLL!).
Is there an easy way to have conditional values in the VERSIONINFO?
I have considered using Resource Hacker in the post-build step but its not clear how this can be used to modify the version info with commad line options.
Thanks
Tony

You can use #if and #endif in your resource script to select different entries. Then just #define the appropriate variable for each build.txtspeak is the realm of 9 year old children, not developers. Christian Graus

Hey, thanks for the reply!
If I remember correctly, I tried this but even with a batch full build, the compiler appeared only to compile the resources once so all of the builds had the same comment.
I can't be 100% sure that this is what happened but I will check.
Tony

| Yes I missed that, you may need to add some extra dependencies to the project, or a pre-build statement of some sort. txtspeak is the realm of 9 year old children, not developers. Christian Graus

Each build will compile the .rc to a build specific .res.
Within the IDE go to Resource View.
Open the .rc file and add/select a Version.
Right-click on the Version and select Properties.
Edit the Condition field....cmk
The idea that I can be presented with a problem, set out to logically solve it with the tools at hand, and wind up with a program that could not be legally used because someone else followed the same logical steps some years ago and filed for a patent on it is horrifying.

The question is how function-level statics are constructed when the function is called on multiple threads?
Problem Description: Deadlock occurs and my application doesn't get terminated. During initialization of local static variable it tries to acquire MSVCR80!_lock and never gets hold on the lock.
Below is the calls stack and you will see that it will never get hold on the lock _mlock
(_EXIT_LOCK1); //C:\Program Files\Microsoft Visual Studio 8\VC\crt\src\crt0dat.c
ntdll!RtlpWaitForCriticalSection+0x132
ntdll!RtlEnterCriticalSection+0x46
MSVCR80!_lock+0x2e MyDLL!_onexit+0x36 [f:\sp\vctools\crt_bld\self_x86\crt\src\atonexit.c @ 103] MyDLL!atexit+0x9 [f:\sp\vctools\crt_bld\self_x86\crt\src\atonexit.c @ 127] MyDLL!__DllMainCRTStartup+0x7a [f:\sp\vctools\crt_bld\self_x86\crt\src\crtdll.c @ 498] MyDLL!_DllMainCRTStartup+0x1d [f:\sp\vctools\crt_bld\self_x86\crt\src\crtdll.c @ 462] ntdll!LdrpCallInitRoutine+0x14
// Code snippet below
void main()
{
atexit(MyCallBack);
exit(0);
}
void MyCallBack()
{
// Waitingforsingleobject() // Waits until all threads are terminated
}
The EXE call DllMain with DLL_THREAD_DETACH flag and we have an explicit handling as shown below
BOOL APIENTRY DllMain( HANDLE, DWORD dwReason, LPVOID )
{
if(dwReason == DLL_THREAD_DETACH)
{
F1();
F2();
}
}
F1()
{
const static CComBSTR bstrMethod = __ FUNCTION __ ;
}
F2()
{
const static CComBSTR bstrMethod = __ FUNCTION __ ;
}
Is it thread safe to have local static initialization within a function. Also I noticed if static variable is once initialized before the exit() of main application I don't see any problem. Can any one please explain what might be issue?
Note: But when I make static variable as non static the deadlock doesn't occur and problem is solved.
Also let me know any alternate solution which might help in this situation Eagerly waiting for reply.irfan

In general a function that uses a local static variable is generally NOT reentrant. A function that is not reentrant is not thread-safe. It isn't merely deadlock, it can also produce bad results.
There is a different instance of an automatic variable for each invocation of a function, but all invocations share one and the same local static. Access to a shared resource from threads needs concurrency control.
In your case you are talking about a const variable. In this case, it shouldn't be a problem except during initialization. Further, the run time library seems to be putting in some concurrency control for what you are doing. This concurrency control is for a different issue and would probably not be adequate for your situation. It did get me to stop and take a broader look at your situation.
You are trying this in DLLMain. You really need to carefully read the documentaiion on DLLMain[^].
In particular:
Warning There are serious limits on what you can do in a DLL entry point.
and
Unfortunately, there is not a comprehensive list of safe functions in Kernel32.dll.
and
Calling functions that require DLLs other than Kernel32.dll may result in problems that are difficult to diagnose.
and
DLL notifications are serialized
The bottom line seems to be that you are getting too fancy for DllMain. I'd suggest thinking about your design and trying to keep DllMain as bare bones and simple as possible.Please do not read this signature.

Hi
I want to kill a process which is running in the memory. I can get its handle by using:
HWND FindWindow(
LPCTSTR lpClassName,
LPCTSTR lpWindowName
);
What function can I use to kill the running process?
Thanks,
|
|
|
|
|
You could PostMessage(hFoundWindow, WM_CLOSE, 0, 0);
...but it is not killing,
the process code may have an own translating of the message,
for example - a question "Are you sure ?" Check your definition of Irrationality[ ^]
1 - Avicenna
5 - Hubbard
3 - Own definition

We use a couple of different functions to do it (probably over-kill) :
Use CreateToolhelp32Snapshot to get a snapshot of the current processes.
After that loop over the entries with Process32First and Process32Next and fetch the name of the process in the PROCESSENTRY32 structure.
And find the process in the list, use TerminateProcess with the handle in the PROCESSENTRY32 struct.
Good luck.Watched code never compiles.

GetWindowThreadProcessId(hWnd,&dwPid);
hProcess = OpenProcess(PROCESS_ALL_ACCESS|PROCESS_QUERY_INFORMATION ,FALSE,dwPid);

Well, Three answers, two using TerminateProcess, one using PostMessage. The latterone may not terminate, the former one can leave DLL's in an indeterminate state. Why not do as Microsoft does: Try Post Message, run a Progress Dialog for say 30 Seconds to see does it terminate, and if it does not, use TerminateProcess().
If the apps you want to terminate are all your own, you can include a special Message Handler for your own windows message: WM_TERMINATE_MY_PROCESSES, and post them to your apps.

Bram van Kampen
