hi,
You can easily bind com components using vs.net sdk. Go to reference folder of your project and right click to get the Add reference option. Choose that option and choose com tab. Then you can browse and locate the directry which contain your dll.

hi,
Refer your dll on namespace reference location.
Like
using system;
using yourdll;
etc.
then
try to create instance on your event handler location.

hi,
Nevar a problem.
I think i already told you about reference forlder.
Right click the reference folder which is there in your asp.net application. And locate the .dll file.
After that, if you try to view the content of reference folder you will came to know u'r dll file is there in that list.
check this much and get back to me.

hi,
In the namespace declaration section try to call your dll file.
like
using System;
using name of your dll;
then you will get all avilable types in button click.
Eg:
using System;
using SockDll;
private void button_clcik(object sender, System.EventArgs e)
{
SockDll.MyClass Obj=new SockDll.MyClass();
Obj.Method();
}
**************************
S r e e j i t h N a i r
**************************
|
|
|
|
|
but on writing Using SockDll;
it gives error
c:\inetpub\wwwroot\WebApplication2\WebForm1.aspx.cs(2): The type or namespace name 'SockDll' could not be found (are you missing a using directive or an assembly reference?)
y it is ???
Regards.
|
|
|
|
|
tell me your .dll is not there in reference folder.
The error is because that perticular dll is there in reference folder.
please check that.

dear paul,
please re-check whether it is working in table select.
dataset.Table[0].Select("Disp==%sdsd%");
(forget abt the above syntax).

Paul,
I know how to use Select with DataTable. I couldn't find any example for LIKE operator from the link that you specified.
Could you please point out specific example out of that link.
Thanks

Hi, I'm trying to connect to my tv tunner but I don't get any sound. It doesn't allow me to change Audiosource (it's always at SPDIF). There's no way to do it. I have tested my app and the Capture application sample in other computers, with exactly the same result: good video but no sound.
What Am I doing wrong? Neither sample app works to me and my friends...
Thank you

|
|
Well, I've solved it manually by changing settings at the Video Crossbar properties page.
How can I do it programatically?
Thx

Hi,
In MFC we had a very nice feature where in we can split the form. Can we do the same thing here. I am designing something like Visual Studio, with tool box on one side and a form (actually a plain user control) where in the tools can be dragged and dropped on the form. But when the forms size is increased, as it is a single view we cannot view the tool box. I was hoping to make something so that the tool box and a property grid stay where they are and the form can be resized in a different view.
I may not have explained few things clearly. If you need more info, pls do write and i will try to explain as much as possible. In short its a visual studio, where in i want the tool box at one side not disappear from screen when the design forms size is increased .
Thank you all.

Hi!
A split form can be achieved with a Splitter (thus the name  ) control.
For example, if you add a TreeView, a Splitter and a ListView to your form and set the Dock property of the TreeView and Splitter to Left and the ListView's Dock to Fill then you get the window layout of Windows Explorer.
You might have to play with the order of your controls so that the splitter behaves correctly.
Regards,
mav

Hi,
Thanks for the reply mav. I have seen examples with splitter and they all deal only with list view and tree view. I tried to use it with other controls (some user controls ) but was not successful. Please let me know if it can be done with controls other than listcontrol, tree control.
Thanks

The Splitter can be used with any two controls, you'll just have to take care that both controls are docked, one of them has docking style Fill and that the order of controls is correct.
