Re: Create new controls in RunTime liqnit6-Sep-05 3:15 liqnit 6-Sep-05 3:15  thanks a lot Have a nice Day Add user control reza toorani5-Sep-05 22:47 reza toorani 5-Sep-05 22:47  hi How can i add user control in class library Multithreading in c# windows application dhol5-Sep-05 21:58 dhol 5-Sep-05 21:58  Hi I have to work on multithreading concepts in c# windows application. Design a form with 3 labels and 3 text boxes and a button. I should enter the time in three text boxes. Three different times. And press the Button. Label 1 should become green color after the entered time period in text box1. Label 2 should become Yellow color after the entered time period in text box2. Label 3 should become Blue color after the entered time period in text box3. I should have three threads to start three processes. Start the three threads in the button click. Thread 1 to start the thread and wait for the entered time in text box 1 and make the label 1 green. And so on. U should enter the time in milli seconds. 1 second = 1000 milliseconds. So if I want to enter 5 seconds. I should enter 5000 in the text box. I should Write a windows application for this. Pls anyone explain me how to do this . pls help me to do this sample. dhol Re: Multithreading in c# windows application CoolAmir5-Sep-05 22:31 CoolAmir 5-Sep-05 22:31  I'm no expert in Threading but i could accomplish the same task without explicitly using threads.

I am drawing lines using mouse events when I draw the second line it will start from the end of the 2 line and when i draw the 3 line which should start from the second line but the problem is I CAN OVERWRITE the first line which should not happen AT ANY POINT OF TIME NO LINES SHOULD BE overlapped. When I press a key like 'C' the first line and the last line should coincide with out overlapping any line. Plz do help me if u have any solution Advance Thanks to all.

Key Chord Sequences Vasudevan Deepak Kumar5-Sep-05 20:08 Vasudevan Deepak Kumar 5-Sep-05 20:08  Visual Studio .NET uses bit of next level keyboard shortcut keys like KeyChord Sequences CTRL+K, CTRL \ etc. I have a couple of questions thereto: (*) In our Windows Forms too, is it possible to implement it by using Keyboard accelerator style itself or is it a Custom Key Press listener? (*) Can this be used as a Global Shortcut key? I think KeyChord Sequences would be definitely be a very unique key sequence to maintain keboard shortcuts for the applications. Please advise...

Heinz_5-Sep-05 20:03 Heinz_ 5-Sep-05 20:03  Hi, This sounds really crazy but a simple "for" instruction doesn't work in none of my programs. The bucle is as follow: for (int i = 0; i == 5; i++) { MessageBox.Show("Hello " + i); } I've tried this simple piece of code in every function i have, it compiles fine but at runtime it never get into the loop. I'll try to reinstall the .NET FrameWork, reboot my PC, whatever. It's so simple but now it don't work. What could be possible wrong? Thanx, Heinz Re: &quot;For&quot; bucle doesn't work in c#?

The reason being that I need structures that can be used for UDP packets that can be filled, sent, received, and later unpacked in the correct order. In C++, these structures can be somewhat complex due to nested structures. However, the example below is a very simple C++ nested structure with an attempted C# conversion. In the C#, I have only one query and that can be seen at the very end when transposing the last structure ie IDENTIFIER_T id[12]; Does anyone know a simple way to convert these simple structures to C#???? C++ typedef struct { int source; int destination; int message; }HEADER_T; typedef struct { double X; double Y; double Z; }VECTOR_T; typedef struct { int id; char[32] IdName; int nameHashId; }IDENTIFIER_T; typedef struct { int id; char[64] dataName; HEADER_T header; VECTOR_T position; IDENTIFIER_T id[12]; char[128] spare; }DATA_T; Attempted C# Equivalent [ StructureLayout ( LayoutKind.Sequential ) ] public struct HEADER_T { int source; int destination; int message; }; [ StructureLayout ( LayoutKind.Sequential ) ] public struct VECTOR_T { double X; double Y; double Z; }; [ StructureLayout ( LayoutKind.Sequential ) ] public class IDENTIFIER_T { int id; [ MarshalAs(UnmanagedType.ByValTStr, SizeConst=32 ] string IdName; int nameHashId; }; public class DATA_T { int id; [ MarshalAs(UnmanagedType.ByValTStr, SizeConst=64 ] string dataName; HEADER_T header; VECTOR_T position; // ????? What happens here???? IDENTIFIER_T id[12]; [ MarshalAs(UnmanagedType.ByValTStr, SizeConst=128 ] string spare; }; Rob -- modified at 1:04 Tuesday 6th September, 2005 Re: C# Nested Structure Marshalling leppie6-Sep-05 3:51 leppie 6-Sep-05 3:51  I think you can use the same as with strings. Look at UnmanagedType.ByValArray and specifiy the size. Last resort, add 12 fields :p To check size consistancy, do sizeof checks in both C and C#. xacc-ide 0.0.15 now with C#, MSIL, C, XML, ASP.NET, Nemerle, MyXaml and HLSL coloring - Screenshots Re: C# Nested Structure Marshalling RobVai7-Sep-05 13:46 RobVai 7-Sep-05 13:46  Thanks but unfortunately the [MarshalAs(UnmanagedType.ByValArray , SizeConst=12)]will not work. It compiles ok but will cause a runtime error because the MarshalAs can't determine the size of the structure. SizeConst can only be specified for fundamental types and not for an array of structures. -- modified at 19:50 Wednesday 7th September, 2005 Re: C# Nested Structure Marshalling leppie7-Sep-05 14:16 leppie 7-Sep-05 14:16  RobVai wrote: It compiles ok but will cause a runtime error because the MarshalAs can't determine the size of the structure. After looking at your code again, it is because you are not using struct, some are class and some classes dont contain layout info, so the runtime will never be able to marshal that. Note: using a fixed layout class is making a pointer to a struct. xacc-ide 0.0.15 now with C#, MSIL, C, XML, ASP.NET, Nemerle, MyXaml and HLSL coloring - Screenshots Save a pictureBox object as JPEG or BMP? boraxx5-Sep-05 18:25 boraxx 5-Sep-05 18:25  Hi, I have a C# .NET framework 2.0 application that draws a bunch of lines and shapes by creating a Pen and a Graphics object and drawing the "art" onto a PictureBox.
