I'm writing a programme for my final project which I have to finish in two days  This programme includes a TCPListener to get some data over TCP/IP protocols. So I've made a second thread for this TCPListener. Otherwise, other components woudn't work at the same time due to infinite loop as u predict. But, now I have an other problem; When I start my thread as I wrote below;
Form1^ s = gcnew Form1();
ThreadStart^ serverDelegate = gcnew ThreadStart(s,&MyMessenger::Form1::ServerActivate);
Thread^ serverThread = gcnew Thread(serverDelegate);
serverThread->Start();
ServerActivate function (which includes TCPListener) works correctly, can call other functions, but while this thread is working I can not control the properties of components of Form1, such as textbox->text. I've tried many things, but I couldn't. Please help me, how can I solve this problem?

Hi, I'm using Visual Studio 2005 C++/CLI. I am trying to automate Excel 2003. I can get the application and workbook and sheets and ranges but I can't seem to figute out what method to use to actually populate the cell with data. With MFC it used to be Range.SetValue but I can't find the new CLI method that does this. The Microsoft site has a location for the Application, Workbook, Worksheet, and Range interfaces but when I go to look at the details of these the documentation says "the methods are listed in the table below" and there is no table.

There seems to be a problem with the Office Documentation but somehow I found my way in, it wasn't pretty.
This[^] seems to indicate that (Value) is a property.
If you are not using the Primary Interop Assembly available from the MSDN web site you should be. It might make things a bit simpler.
Also if you are struggling with the CLI part start a C# project and reference Excel assembly in there so you can use it to see how to work with the Object Model then port to CLI. Alternatively you can build your own C# Library that encapsulates what you want to do with Excel and then use that interface in your CLI code.

Thanks Mike,
I will focus on this. I am using the PIA's.

Hello,
I am trying to implement a bit shift function that would shift bit positions either to the right or left using the codes below.
The bit shift is not working can someone help with why it is not working? 
public: System::Void apply_BitShift(String ^myString, String ^direction, int numOfShifts)
{
bitShiftVal = "";
array<__wchar_t> ^shiftArray = gcnew array<__wchar_t> (myString>Length);
//copy characters from myString into shiftArray
myString->CopyTo(0, shiftArray, 0, myString->Length);
if(direction->Equals("left"))//Perform left shifts
{
bitShiftVal = gcnew String(shiftArray, numOfShifts, (myString->Length)-numOfShifts);
for(int indx=0; indx<numofshifts; indx++)
="" bitshiftval="String::Concat(bitShiftVal," "0");=""
="" }
="" else="" if(direction-="">Equals("right"))//perform right shifts
{
for(int indx=0; indx<numofshifts; indx++)
="" bitshiftval="String::Concat(bitShiftVal," "0");
=""
="" for(int="" indx="0;" indx<shiftarray-="">Length-numOfShifts; indx++)
bitShiftVal = String::Concat(bitShiftVal, shiftArray[indx].ToString());
}
}//end of apply_BitShift

Have you stepped through your code to see what exactly is happening?

I'm not seeing any bit shifting going on in your code...

we probably aren't seeing the code correctly due to the '<' '>' characters. Also in my browser there is a giant Fish Filet obscuring his post.

I'd say the first clue would be 'try the visual C++ forum'. It doesn't seem likely from your post that you're using C++/CLI

A wild number is a string containing digits and question marks (like 36?1?8). A number X matches a wild number W if they have the same length, and every non-question mark character in X is equal to the character in the same position in W (it means that you can replace a question mark with any digit). For example, 365198 matches the wild number 36?1?8, but 360199, 361028, or 36128 does not. Write a program that reads a wild number W and a number X from input, both of length n, and determines the number of n-digit numbers that match W and are greater than X.
Input (filename: B.in)
There are multiple test cases in the input. Each test case consists of two lines of the same length. The first line contains a wild number W, and the second line contains an integer number X. The length of input lines is between 1 and 10 characters. The last line of input contains a single character #.
Output (Standard Output)
For each test case, write a single line containing the number of n-digit numbers matching W and greater than X (n is the length of W and X).
Sample Input and Output
36?1?8
236428
8?3
910

B.in Standard Output

If your homework is not for .NET, then you've posted it in the wrong forum. either way, you need to do your own homework, post questions only when you've tried to write it yourself and are stuck on something specific.

I have a windows form based application, which creates an instance of another class, to which it passes a pointer to itself in the constructor as 'this'. The form has a couple of __property methods, and I'm trying to get the other class to use those methods to push some data back up to the parent form.
For example, let's say my Form1 has a method:
__property void set_MyNumber(int theNumber) {mynumber = theNumber;}
Form1 instantiates another class:
myThing = new CmyOtherClass(this);
Now, down in the other class, I try to access the properties like this:
myParent->MyNumber = 3;
What I get is the following error:
error C2039: 'MyNumber' : is not a member of 'System::Windows::Forms::Form'
I'm fairly sure that the pointers are right, because the following code works fine:
MessageBox::Show(myParent->Width.ToString());
However, it just doesn't seem to recognize the properties I created in the Form1 class. Is there some header or include or using thing that I need to add to make the properties work?
To broaden the question a bit, is this totally the wrong approach? I thought perhaps using delegates might be a better answer, but I seemed to run into similar problems with them as well.
What is the best way to pass information from a subordinate object to its parent?
Thanks for any insight.

Are you passing a 'System::Windows::Forms::Form' pointer to the CmyOtherClass constructor or
a pointer to an object of the type of your Form-derived class?

Ahhh, well, the constructor for the other class is like this:
CmyOtherClass::CmyOtherClass(System::Windows::Forms::Form* callingForm)
and back up in Form1, I'm passing 'this' to the constructor of the other class.
I'm inferring from your question that I should have the constructor look for a pointer to a Form1 object, but what's the syntax for that?
(And BTW, thanks for the quick reply  )

You'll need to change the constructor to take an object of the type being passed instead of a
'System::Windows::Forms::Form' (the base class) pointer.
Also, if you are storing the passed pointer in a CmyOtherClass member variable, you need to
change its type too.
That way the compiler will know the existence of your properties

Hi, I have an request: I need someone to create article with OpenGL. There is one, but it's very simple and many users have problems with it( me too ). Plz if You can: create a form with OpenGL rendering within and some edits witch will change rendered objects properties( size, color, rotation or something like that). I hope there will be someone who will be able to handle this request. Thanks!

Hi, I'm using Visual Studio 2005 C++/CLI. I created a dialog box by adding a new windows form item. In the form designer I set the FormBorderStyle property to FIXED DIALOG, the MinimizeBox and MaximizeBox properties to false. The I add two buttons and set their captions to OK and Cancel and their respective design names to buttonOK and buttonCancel. Then I set the AcceptButton property to buttonOK and the CancelButton property to buttonCancel. When I run the app and ShowDialog() the dialog recognizes the Cancel button and the escape key and closes the dialog but the dialog does not recognize the OK button or the enter key. Do you have an idea as to why?
Thanks
Buck

As long as I can answer my own questions then life is good. It appears that the DialogResult property was not being set for either of my dialog boxes that was exhibiting this behavior. So it was simply a matter of selecting the OK button, then selecting its properties and setting the DialogResult property to OK. The cancel buttons DialogResult for whatever reason seems to be set to Cancel automatically.

Hi, I'm using Visual Studio 2005 C++/CLI. I placed a group control on my form and then added 8 radio buttons to the group. The first radio button has TabStop set to true and the rest have the tab stops set to false. When the application runs the tab order seems correct, and when I use the arraow keys to select a radio button the arrow moves from the last radio button back to the first as you would want. The question here is, I can't find any examples of C++/CLI that show how to determine which button was selected. I tried using the first radioButton->TabIndex::get() to no avail. What is the proper way to find out which of a group of radio buttons has been selected?
Thanks
Buck
