Hi,
I want to create a SDI application with toolbars.
If I click on each tool, it will open up a dialog box.
I want to diaply the content of a particular edit control from a dialog box to the SDI window?
How can I do that? any help is highly appreciated.

Thanks,

for each buttons in the toolbar, you create an handler ( ON_COMMAND ).

in each handler, you create a dialog; which you previously created in the resource editor; and yo created classes for each dialog.

I want to diaply the content of a particular edit control from a dialog box to the SDI window?

Huh ?

Well to do that assume you are calling your manu dialogs from your view class .
Declare the Dialog objects in view.h and call dlg.DoModal() in the button event handler.
if( dlg.DoModal()==IDOK)
{
//access the edit control's contents and copy it to a global string ...
}
Now Dig the msdn to find out how a text editor program works so that you can display the contents in your view . ( I ha done it but forgot )

Anyone know how to detect this?

Creating Stochastic models (Probability density functions) in Visual C++6.0

I am building some stochastic models for risk analysis...so I need to build things like influence diagrams, decision trees etc. These are easy to do in Excel, but we would to rebuild the model using Visual C++ 6.0. How do I build and present, using a graphical interface, distributions such as normal, lognormal, poisson, uniform and binary distributions?

I dunno what a stochastic model for risk analysis is, but Excel is not programming. VC++ isn't going to provide you with a graphical interface to do this stuff, you need to write code to do it.

Accessing ActiveX in VC++ 1.52

Wow. I haven't used that since programming for Windows 3.x. If I remember correctly, I don't believe this version supported ActiveX. It certainly doesn't produce 32-bit Windows programs. You might want to get a slightly more up to date compiler. You can download the free Visual C++ 2005 compiler here[^], or get yourself a copy of Visual Studio 2003.

Inordinate Delaying in Form Display?

Hello! I'm attempting to write an application in VC++ .NET 2003. My application works alright, but it takes at least 10 seconds for the Form to be displayed.

This happens not just on my work PC (P4 1.5GHz, 768MB RAM) but also on my PC at home (AMD Athlon XP 1700+, 768MB RAM)

I've written a similar App in VC# and the Form is displayed almost immediately.

In VC++, the Build Time is displayed as 4s. It then takes AT LEAST 10 seconds for the Form to be displayed.

My Application is neither large nor complex.

I am new to VC++ and my understanding is that all the code is written in the Form.h file, and nothing needs to be added to the Form.cpp file. Is that correct?

Do I need to change any Solution properties? They are all currently set at their default values.

I would really appreciate any suggestions to improve the speed of Form display.

Thanks!

If in my main program I have a variable that holds some data. Can my worker threads (I could have any number of worker threads) that I've created access this data....and can I pass a message to them? (the worker threads)

While passing data between threads is certainly possible, it's not without risk. Read the following two articles on the subject:

PostThreadMessage will post a message into a thread's queue.
You can retrieve it with GetMessage or else wait for messages or other waitable objects to be signaled by using the function MsgWaitforMultipleObjects.

I would not read or write any data shared between one thread or another without guarding it with a critcal section, a mutex, or some other protection.

If you only need to modify a single long value, you can investigate InterlockedIncrement, etc.

If you want to pass the variable during startup of the thread itself - you can do as below..Assume var is the varible ( it can be a structure also ) you have to pass to the thread function ..

ULONG __stdcall ThreadFunc(LPVOID pParam); //declare thread function
CreateThread(NULL, 0, ThreadFunc,(LPVOID)var, 0, NULL);

Now "var" is passed to the ThreadFunc . Inside the ThreadFunc you can retrive the void param back to the original type as below

ULONG __stdcall ClientThread(LPVOID pParam)
{
int param=(int)pParam; (or) int param=(int*)pParam ; or replace int with your variable's type...

return 1;
}

and If you want to pass the param when the thread is running you can always use PostThreadMessage() with the same way of LOVOID(pParam) ...

Can anyone help me convert this for loop:

PTCHAR Value = new TCHAR[2];
PTCHAR MRUList = new TCHAR[27];

//Get MRUList from the Registry
_tcscpy(MRUList,_T("abcdef\0"));//sample string

INT MRUListLength = _tcslen(MRUList);
//This is where I need the help
for(INT i = 0; i < MRUListLength; i++)
{
wsprintf(Value,_T("%c\0"),MRUList[i]);
//do something with Value now
}

//would delete the 2 PTCHARs but this is a sample

into something unicode compatible? I know I would need to use CharNext, I just can't figure out how.

Also I have heard of _TINT, Do I need to use that?

While it has nothing to do with Unicode, the extra '\0' is not necessary.

KingKruncher wrote:

How about:

for (LPSTR lpValue = MRUList; lpValue && *lpValue; lpValue = CharNext(lpValue))
{
    ...
}

Finding COM Memory Leak in ISAPI Extension

Turtle Hand25-Oct-04 9:36

I need some help finding a memory leak in an isapi extension I am maintaining. This extension leaks memory at a rate of 7mb every 5 minutes. I've been thru the Code Project article: Memory(-Leak) and Exception Trace (CRT and COM Leaks) by Jochen Kalmbach and it seems to be COM objects that are leaking. His approach doesn't work well with COM.

I've tried using UMDH.exe from MS, but am not able to set gflags for inetinfo.exe.

Any help at finding these leaks and/or using umdh.exe is appreciated.

I can set the stack trace flag for inetinfo using gflags here (on a XP Pro SP2 box, running as admin). Is there an issue with permissions on your machine or is gflags just not working?
