 I am using a web user control with infragistics spell checker to spell check a text box. When I click the image button to invoke the spell check method the screen refreshes and the spell checker form is not displayed. What am I doing wrong?

1 - asking an ASP.NET in the VB.NET forum
2 - asking here instead of asking Infragistics
3 - asking us to help you without posting any code, so we don't know what you could be doing wrong

It's three files. One is the asp code for the ascx file and the last is the aspx file with the infragistics spell checker designer.
I really wanted to know if you can invoke a method (the aspx file) from a web user control?

|

The code works fine when the first file is an aspx file and the second file is an aspx file. When the first file is the aspx file and the second file is the ascx included in the aspx file and the aspx file that spell checks is started from the ascx file the form just refreshes.

Does anyone know where I can find some sample code that demonstrates a screen capturing routine where the user goes to an area on the screen holds down the left mouse button, drags the mouse over the area they wish to capture and on the mouseup event saves the selected area into a bitmap file?
Thanks,

Hi
I have a large multithreaded Windows Forms application and its leaking GDi objects (VB.Net). The application has a single MDI and multiple forms with multiple tab pages in each form. At any time there is only 1 MDI Child loaded. In the application there are no explicit GDI calls, we do have new fonts getting created but no images etc or any enhanced graphics drawing.
Every time a new form is loaded, the old form is disposed and the contained tab pages are also disposed. We are disposing even the classes. We ran the application with Memory Profiler and have not found any left over objects in the application name space.
Inspite of that the GDI count keeps increasing by ~50 handles every time a new form is opened and closed.
Any help in tracking down the culprit object which is leaking the GDI resources is greatly appreciate.
Thanks
Balakumar

Do you dispose of them ?

Hi
Thanks for the reply.
We have new fonts created like this in the INITIALIZECOMPONENT section of the New Form.
'
'Label46
'
Me.Label46.Font = New System.Drawing.Font("Tahoma", 8!, System.Drawing.FontStyle.Bold)
Me.Label46.Location = New System.Drawing.Point(840, 51)
Me.Label46.Name = "Label46"
Me.Label46.Size = New System.Drawing.Size(32, 16)
Me.Label46.TabIndex = 40
Me.Label46.Text = "S/L:"
Are we expected to DISPOSE of these Fonts too? It seems counter intuitive, and its strange that if we just use the Microsoft Sans Serif (the default font) no New is added.
Thanks

Hi,
when you close a form:
1) do you Hide it or Close it?
2) is it actually gone completely, or do you keep some reference to it somewhere,
say in an ArrayList or List so you know which forms are (or have been) open?

That certainly could be an issue.

we explicitly close it (no HIDING) since the application is fairly large. We have also used memory profiler to monitor objects creation and destruction, and have found that the objects (ie the ones in the application namespace and to a large extent even in the system and system.windows.forms etc namespace ) are getting garbage collected.
One mistake (according to most of these posts) that we do have in our app is that we are forcing a GC.Collect, but would that cause GDI objects to not get collected?
Thanks

Are you running the garbage collector? I would expect that if you create a font object and never dispose of it, the underlying font resource will get released when the object is garbage-collected, but unless you force a garbage collection (generally not a good idea except for diagnostic purposes) that may not happen for awhile.

No, it won't. You have to explicitly call Dispose on it to release the unmanaged resources. The GC will not do this for you.

I would have expected that any of the framework objects that use system resources would have finalize handlers that would free such resources. Obviously if you create your own objects that allocate system resources via API calls you need to free them, but I would expect Microsoft's framework objects should take care of that.

hi prubyholl
its Easy, just go to your Projecty Explorer and right click, select a file system, in the file system view, select the Application Folder and if you see your controls , just right click in them and go to their properties and look for Hidden and select "true", and your controls will be hidden.
Hope this helps
Thanks

cn = New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\ABS.mdb")
if the company owner wants to change the file location to the current directory means each time he has to change the path or is there any way to tell or define the cuurent directory like VB.
in VB we give &APPPATH& like this any thing in VB.NET.
i am using VB.Net 2005 Professional version.
