If you're not using managed C++, then you're posting your question on the wrong board.
You should post on the Visual C++/MFC board.

Yes.
You could also look into using the Month Calendar Control[^].

Thanks I appreciate it but the user was pretty clear on wanting to be able to enter the data by hand.
I appreciate the suggestion though!

The SetWindowText() API can be used to set the text of the LTEXT control.
To convert a numeric age value to a string for display, you could use the CRT
sprintf_s() function.

char alpha[10] = "abcdefg";
string beta = "abcdefg";
alpha[1]= '\0'; gives the following result : alpha = a
beta[1]='\0'; gives the following result : beta = a cdefg
How can i use '\0' in strings as i use them in an array? I mean iwant that '\0' replace 'bcdefg' in string not just 'b'.
Thanks

#include<stdio.h>
void main()
{
char string1[10]="abcdef";
char string2[10]="abcdef";
string1[1]='\0';
string2[1]='\0';
printf("%s\n%s",string1,string2);
}
result:
a

Unfortunately, he is trying to modify a std::string and not a char array string.

Apparently, you are printing the result with the following: std::cout << beta << std::endl. If you print it with std::cout << beta.c_str() << std::endl, you get the desired print out. However, if you actually want to remove the characters following 'a' you can do this:
#include <iostream>
#include <string>
int _tmain(int argc, _TCHAR* argv[])
{
std::string beta = "abcdefg";
beta.erase(beta.begin() + 1, beta.end());
std::cout << "Result #1: " << beta << std::endl;
std::cout << "Result #2: " << beta.c_str() << std::endl;
return 0;
}
Also, please post C++ questions in the C++ forum and not the C++/CLI forum.

You are little bit consfused with char[] and std :: string
Please Clear about that.

Hi.
I got my answer but you're right. I'm reading the c++ Primer + and there are different chapters to cover String. I did not read the chapter which explains in details.
It sucks to be a beginner

Hi, I am using Visual Studio 2005 C++/CLI. I want to print via the print preview dialog. I set up the printPreviewDialog and created a document I could view with the printPreviewDialog. But when I used the print button to print what was being displayed only some of the document was printed. The bottom of the document was cut off. I thought that the print preview dialog showed what the printed output would look like (WYSIWYG) before you decided to print it. Isn't this the case?

Here is the code snippet of my application. background thread is a managed thread.
Code Snippet
public ref class Form1 : public System::Windows::Forms::Form
{
private:
Thread^ myThread; //Managed Thread Handle
IDiscovery* discObj // Pointer to unmanaged type
public :
static System::Void ThreadProc(System::Object^ pv)
{
System::IntPtr^ ptrDiscovery = cli::safe_cast<system::intptr^>(pv);
IDiscovery *discObj;
discObj = (IDiscovery *)ptrDiscovery->ToPointer();
//get the list from IDiscovery
discObj->discoverList(false);
}//END OF THREADPROC
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e)
{
System::IntPtr^ pV = gcnew System::IntPtr(static_cast<void*>(discObj));
myThread = gcnew Thread(gcnew ParameterizedThreadStart(Form1::ThreadProc));
myThread->Start(pV);
}//END OF FUNCTION
At times I am getting following exception:
An unhandled exception of type 'System.AccessViolationException'
Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
I am not sure whether this the right way to do it. Please suggest.
Thanks a lot,
Arti

is never initialized in the code you posted and could be the source of the error

It is initialized in the constructor. I just posted part of the Form1 class.
Also it works sometimes and sometimes I get this Exception

Hi, I am using Visual Studio 2005 C++/CLI. I am at the stage where I am rewriting the same application several different ways. This allows me to become more familiar and comfortable with the CLI syntax. In doing so there were a couple of Forms that had a lot of controls on them. Rather than re-create the Form and add all of the controls again I decided to used the Add->Existing Item command to add the Form information. Before adding I copied over the FormX.h, FormX.cpp and FormX.rex files into my current project directory, then I added them to the project. This works great except when I decided that I needed to modify the FormX[design]. I can't seem to get the FormX[design] window to open. Can someone tell me the correct procedure to add an existing Form from another project and then be able to modify the Form in the FormX[design] window?
Thanks
Buck

Sounds like you're asking a C++ question, which belongs in the Visual C++ forum. If you want to use .NET, this is the place to ask.

Did you include iostream without .h?
