Hi All,
I have created one DLL having some functions as follows..
I want to call them from VB.net and C#.net.

1)   Function CONVERTPWDATA ( PASS1,PASS2 : INTEGER; IpStr : PWord; OpStr : PChar;
         LangName : LongInt; AFontType, BFontType : LongInt ) : PChar; StdCall;export;

2)  Function CONVERTDATAEX ( PASS1,PASS2 : INTEGER; IpStr : PChar; OpStr : PWord;
         LangName : LongInt; AFontType, BFontType : LongInt ) : PChar; StdCall;export;

Can anyone help me for Compatible Data types in .net for Delphi Data Types..

My Second Question IS

How to pass Unicode Data from .net and How to receive it back from Delphi DLL.

Thanks in Advance..

I have never failed,I just found 1000 ways that never works.
Regards,
Victory.

well, thats a start point. You need to find ways to handle videos in c#. there are some open source libraries available. google for them.

a simple search in CodeProject would have given you the answer as well.

Cutom Control painted with GDI - Controls added or painted

Hi !
I'm currently making a custom TreeView inheriting "ScrollableControl" and all parts are painted with GDI. Now, I'm going to implement the checkBox and I would like painting them too.

Is it reasonable for the performances of the application to paint controls instead of adding real controls ?
I have the same question for all parts like the "arrows / plus-minus" icon.

I want adding possibility to format the node text. Adding colors for some words or underline ...etc...
Actually, this text is painted too with GDI "DrawString". What is the best solution for you to format this text easily for the control user ?
Asking to user to enter RTF formating or Html formating and parse it before paint ?

Hi,

maybe not directly an answer to your question, however: have you read the documentation on ControlPaint class?

yes.

a control is a very expensive ressource, and a filled treeview may have up to thousands of Nodes.
I never tried, but i don't think, an application with thousands of Controls will run propperly.

Really thanks for yours answers Smile | :)

I did not know at all "ControlPaint" Class, but Just before looking at this, I have founded for example "CheckBoxRenderer.DrawCheckBox" ... and make the relation with "ControlPaint".
Very very cool !

It seems to be perfect for me I think. If I have understood, that must make it possible to have the faithful chart of controls without having their weight ! Right ?

edit:
After trying both solutions, it seems "ControlPaint.DrawCheckBox" paint a checkBox without theme, compared to "CheckBoxRenderer.DrawCheckBox" who paint it with theme.(I'm under XP)

Im doing an online chat which allows users to interact, keywords will be stored within a database.
When the user wants to submit a message (they have written in a text box)the content within the textbox is examined so that it doesn't contain any of the words that are in the database, if it does then the words will be highlighted and the message won't be sent. Can anyone help me on how I can do this? I really need help Unsure | :~

You have to use Ajax for implementing this functionality. You get help from following links,

I can provide you with the general explanation.

What you need to do is, Firstly fetch the words you dont want to publish on your chat. Store it in an array. A generic list would be great if you are aware of that.

Then when any user sends the data, create a for loop where you will have to search for the specific word on the sentence. For every matched word, you will have to change the font color of that particular word, and reattach the word back..

There are many versions available, but this is the simplest one, when you wish to filter bad words, (which are upto 20-30 only)...

I hope this helped you..

You might want to have a look here.

Try including a publisher name in your setup file and see if it stops this popup from appearing.

winsock control is in VB6. if you are developing application with .Net Frame work (VB/C#) go through
the namespace System.Net.Sockets

search in GOOGLE you will find no of examples.

There is no winsock in vb.net. I suppose you could register the old control if you can lay hands on it.

I am using the datareader to read through a foxpro table and when there are multiple records in the table it will only read the first one and then drop out of the loop. Any ideas on why it is doing this?

If DR.HasRows Then
           While DR.Read()
              random code here...
              uploadDate = sql statement...
              uplDate = New OleDb.OleDbCommand(uploadDate, objConnection)
              DR = uplDate.ExecuteReader
              DR.Read()
           End While
End If
