Good luck - once you recreate the forms as tab pages, it's pretty straightforward.

ok so what do i do with

if (tabControl1.TabPages.Contains(tabPage1))
{
tabControl1.TabPages.Remove(tabPage1);
}
else
{
tabControl1.TabPages.Add(tabPage1);
}

where do i add them in my program?

how do i add event handlers to hook up to the buttons on the main page, and when i press a button, a tab page appears or disappears?

can u tell me where do i go to in order to add event handlers as well as the steps to do it..

That's what the method does which is called when you press a button. For the sake of time, I'd just add a public method for each button to call that does this, and call it from your main dialog class.

Do I have to run an ActiveX in Visual Studio environment.

2-Aug-05 19:29

it's ok.. i managed to do it..
but it's not the way i want it exactly..

1)how can a user close a tab page including the tab after viewing it??
i dont mean it this way:

tabControl1.TabPages.Contains(tabPage4)
{
tabControl1.TabPages.Remove(tabPage4); }

2)how do i disallow the user from opening the same tab page of information?
i dont want to disallow the button function.. just want to disallowing opening of tab page..

thanks

I’m developing an C# Application that uses an (old) ActiveX that I still do some modifications on.
My problem is that I can’t compile the ActiveX while I’m running my Applicaion project. That’s because the ActiveX is running in the environmet (on one of my Forms). Any tip how to handle my problem…

You must close your application if you want to comiple the ActiveX control. Generally people change the name of the .ocx file generated after the build to see if it compiles correctly in this situation. If you are happy with changes of ActiveX control, close the application, change the name of the output ActiveX and recomiple. Start the application again and you are done.

are you sure that exception type is FormatException
any way why not try some thing like this
try
{

}
catch(FormatException ex)
{}
catch(Exception ex)
{}
finally
{}

Hi,
Thank u for ur reply.
I tried the way u suggested.
When I printed the message of exception that is of system.formatexception.
but that exception was not being caught.
Then I tried to know the type of exception and I got it was the ArgumentException and I tried to catch that and I got success.

But the question is that if it is ArgumentException then why the message shown is of system.FormatException.

Can u plz clarify this?

Thank u again.

Following is the code that I am running in a clikc event of a button followed by the message that I am getting when the exception is caught.

private void bttnSaveUserPersonalInfo_Click(object sender,EventArgs e)

string strUserRoles = String.Empty;

{
drwNewUserPersonalInfo = dvUserPersonalInfo.AddNew();

dstUserPersonalInfo.WriteXml(MapPath"./DataBase/UserPersonalDetails.xml"));
ViewState["NewUserLoginID"] = txtUserLoginID.Text;
}
catch(System.ArgumentException) //This exception is caught the message *
{
Response.Write(x.Message);
}
}

//Message displayed when ArgumentException is caught

from the following line
drwNewUserPersonalInfo[5] = txtUserDateOfBirth.Text
that you set string value to datatime type so this generate exception
even if the string formmated like date
so try to use some thing like this
drwNewUserPersonalInfo[5] = DateTime.Parse(myDateTimeValuetxtUserDateOfBirth.Text)
look at msdn to other overloading version for this methof

Using C# forms and graphic box.

I am looking for help creating a form in which i have a graphic box. In the graphic box I can load an image that is 1024x768 in size. I want to be able to add a graphic and lock it by the x, y cord, on top of the other graphic in a seperate plane. Is this possible and does anyone have any ideas on how to make this easy to code and stable?

Is a graphic box a picture box ? If you want to draw images in layers, you need to do it yourself.

Well, the quick and easy way, at least.

Like I said, you need to draw the images yourself. Handle OnPaint and draw them there.
