Hello,
I'have to create an application that uses a listView. The listView in C#.net 2003 has grid with horizontal and vertical lines. How can I do so as I can make it have only vertical lines? If possible, help me please.

so far in my knowledge Gridlines can only appear in Details view when set to true. if anybody else have any knowledge about removing horizontal or vertical line i'm interesting to know it too.

regards.

The ListView is one of the most limited controls in .NET when it comes to customising apperance and manipulating sub items. I have tried to use one in an application and get it to do what i want for a week now and read much on it, but never came across showing only vertical or horizontal lines.

I think the only way to do this would be to extend the ListView class and overwrite all Painting methods with your own

Dear gurus,

my app has a rich user-interface which I have to test extensively by mouse-clicking on all the menus, buttons,.....

My idea now is to create a small tool which sends all this clicks,... automatically to my application for testing the user-interface.

Does anyone have an idea how this can be accomplished?

My best whishes and thankyou for your help ! ! ! !

You can write a batch file to delete the image from the folder and call the batch file using System.Diagonastics.Process.Start();
E.g
In batch file:

Del <file path="">
exit

After saving in database:
System.Diagonastics.Process.Start("C:\<batchfilename>.bat");

Hope this helps.....
Thanks

It means the host is not responding. Try to: telnet whois.wildwest.net 43 and you will see it fails.

Hi,
I have a VB application using a .Net(C#) dll.I made the application wait for particular time from the .net dll and during the wait if i move between other open windows,the VB application gets hanged or becomes blank screened.

I tried using System.Windows.Forms.Application.DoEvents() to repaint the Vb application but it is that effective but of course makes little difference.

I totally clueless

I got the same problem, but I made my program wait until another program is loaded.

I´ve overcome this problem by making a loop on a timer, so It checks every 300ms if the program is loaded, so it´s not needed to wait anymore. =D

Do the waiting operation on a separate thread[^]. That way, the UI will remain responsive while you wait.

inheriting from tabPage class

Hi
I need some help with coding my class.

I want to create 2 different types of TabPages that will appear on my single TabControl. For eg. a CustomerTabPage and EmployeeTabPage. So I assume I should create 2 customised TabPage classes?
So if im receiving an employees details i will create an instance of Employee and create an instance of EmployeeTabPage(myEmployee) and pass it myEmployee to create a tab page that is unique to employees and adds all myEmployee's data to the labels on that tabPage.

Now the problem I have is how do I add the controls that will appear on my CustomerTabPage or EmployeeTabPage? do I code it in each class of TabPage that I created?

plz help!

Same way you'd add controls to an inherited Form:

<br />
...<br />
this.Controls.Add([some control]);<br />
...<br />
<code> <br />

Are you going to have more than one Employee Tab Page open at any time or likewise more than one Customer tab open. If you're not then it's an overkill to create an inherited tab control.

If you are using more than one instance of each type of tab control then basically you need to do this:

Inherit from a TabPage (easiest way to do this would be to add a UserControl to the current project from VS and then view the source code and change it to inherit from a TabPage).
Add all the code required for these tab pages.
In your event handler / what ever you are using to add tab pages replace: this.tabs.Pages.Add(new TabPage()) with this.tabs.Pages.Add(new CustomerTabPage())

You know you're a Land Rover owner when the best route from point A to point B is through the mud.

hello:
I'm trying to generate code using the CodeDom, and I need to know how to get an expression from an assign statement.

I'm using CodeBinaryOperatorExpression but I get the generated code within parenthesis, for example:
( a = 0 );

I'd like to know if I can get the code without parenthesis using the previous class or someone else.

Thanks
