I think that it isn't the case. If you forget the std namespace, you will get an Undeclared identifier error, not linker error.

What I'd like to do is this..
When I put '1' to the edit ctrl, the contents of editctrl should be changed to '2', if '2', then should be '3' and so forth..
That's why I used EN_CHANGE event handler..
In the handler, at first I read the int value of edit ctrl by GetdlgItemInt API.
then add 1 to the value,
finally called SetDlgItemInt with the new changed value..
But the result was the infinite loop..
does that make sense?
That's because SetDlgItemInt API cause new EN_CHANGE event.. before the first event finished the job..
How can I solve that problem?
As I said before, the contents of edit ctrl should change simultaously as I typed the value..

Have you tried using SetWindowText() instead???
How do I print my voice mail?

|
|

sure..
It also cause infinite loop

Simply use a flag in your OnChange handler. Set it to true before calling SetDlgItemInt and set to false afterwards. At the start of your handler, check the flag.
CMyDlg::OnChangeMyEdit()
{
static bool flag = false;
if (!flag)
{
UINT number = GetDlgItemInt(IDC_MY_EDIT, NULL, FALSE);
number++;
flag = true;
SetDlgItemInt(IDC_MY_EDIT, number, FALSE);
flag = false;
}
}

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?

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.

I am new to Visual C++ and was wondering if there is any way to call ActiveX controls in Visual C++ version 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.

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)
Thanks

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.

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