Hi there
I have a problem where the designer does not support manipulating my third party controls. They can be manipulated programatically with ease. However i would like to exploit the designer for at least previewing the changes.
What i initially wanted to do was insert a method call into InitializeComponent() so that my changes would be picked up in the designer for previewing. But i guess this isn't the way to go?
Anyone any thoughts? or suggestions on how i could achieve this?
Cheers

Hi. I built a client/server system that communicates with sockets. I used System.Net.Sockets.TcpClient and NetworkStream. I wonder if there is a simple way to encrypt the data so that it can not be viewed from outside. Would be greatful for any help

There are plenty of built-in classes to aide you. See the System.Security.Cryptography namespace and its members.

Hello,
I'm developing a windows form client application. It has to work with our server application.
Our server application is a scanning application which needs .tiff files.
What I want to do is to "scan" digital documents such as .doc, .rtf, .pdf, .txt and convert them to .tiff files so the server can handle them. One problem I don't know how to do, and where to start.
So does anyone know a solution for this problem, or at least a direction to look?
Thanks....

For text, you could just create an in-memory bitmap, draw the text on it, and save to tiff.
For rtf, you should be able to do the same using the RichTextBox control and the DrawToBitmap method of the Control class (.NET v2).
For proprietary, closed types such as doc and pdf, you might need some library to parse them out for custom rendering. I can't help you there; I know there are several PDF reader and writer SDKs out there...I'm not sure if any of them support rendering them to bitmap.

Is it possible to get a readily available directory and file browser control of like windows explorer so that i can have it populated in a treeview from which i can choose whichever file i want to open.

I have a TabControl 'tabcontrol1', which i am populating with 5 tabpages at runtime. Now i also have another TabControl 'tabcontrol2' which has 2 tabpages of its own already. I want to add 'tabcontrol2' on every one of the 5 tabpages of 'tabcontrol1' when they get created during runtime.
Any suggestions !

You cannot add a control to multiple parents, AFAIK. Since only one tab can be viewed at a time, just add the tabcontrol2 to whichever page happens to be visible at the time.

Hi,
I want to perform some action by event handling when
the app window go top and not go top when the user choose
another application on the desktop.
I have try Form.Activated, Form.Deactivate, Form.LostFocus,
Form.GotFocus, Form.Enter, Form.Leave, but none of them work !
Could any one help me pls ?
Thanks

When the form becomes the active form, you should get an Activated event. We would need to see your code if something is not working right.

I would wrap up the appropriate C++ functions in Managed C++ and then access the managed code from C#
Ant.

do You mean that i have 2 implement all the functions in a c++ class and then import it in c#?
I am a newbie so i didn't actually understand what do u mean. Can u give me example to make me understand more quickly....
Kind Regards

See Nish's article on C++/CLI[^]. Basically, it allows you to compile C++ and expose certain functions to pure managed languages, such as C#.
In C++/CLI, define a C++ class like this:
public ref class MyClass
{
void DoSomething()
{
}
};
Build this C++/CLI class a .dll.
In C#, add a reference to the C++/CLI dll you just built. You can then call the DoSomething method as if it were written in C#. It's really great. Go read Nish's article linked above. There's another article[^] over at MSDN as well.

I understand your idea...
I have 2 define/call all the functions which I need, from the API in c++ class and then include that class in a c# project.
Can you tell me that wouldn't it be better to directly call the functions from the API in c# (I think there is "dllimport" which I am not totally familiar with).
The reason is that my project deals with real time data and I need high speed response. Using indirect function calls may slow up the process???
... What is your opinion ....
Please comment ASAP

C++/CLI is far faster than using dllimport (which is part of P/Invoke). If you read Nish's article linked above, you could see the performance results yourself.

And when I use this code
dataGridView1.DataSource = myDS;
It doesn’t show anything !!!
string cmd = "SELECT UniversityDB.ID, UniversityDB.UniID, UniversityDB.UniCode, UniversityDB.UniName, UniversityDB.UniAddress, UniversityDB.UniDetail, UniMajorDB.Major, UniMajorDB.Level " + <br />
"FROM UniversityDB INNER JOIN UniMajorDB ON UniversityDB.UniCode = UniMajorDB.UniCode = '" + UniCode_tb.Text + "'"; <br />
<br />
MyAd.SelectCommand = new OleDbCommand(cmd, MyConn); <br />
MyAd.Fill(myDS); <br />
dataGridView1.DataSource = myDS.Tables[TableName];
