OK, now it's starting to make sense. The reason to have the conection string in a class, is for that class to be part of the data layer. It should therefore expose methods to get the data you need, which can then be called to set the datasource of the combo box.

Hello
In my C# program I got a class which has more than 200 Public methods and 50 private methods. Will the object created for this class utilize all these methods size ? How can I find out how much space is utilized by my object.
Is it a good practice like having more number of methods in single class ? Will this make any performance issues ?

I really doesn't know where to start to explain because obviously your knowledge of how compilers/programs work lacks a lot of stuff 
But anyhow: the size of an object has nearly nothing to do with the number of methods (methods reside in the compiled code only once). Only fields (i.e. private int i) add to the size of an object.
And that number of methods is seldom advisable. A class should exist for one single purpose and 200 methods for a single purpose? Maybe you should split the class up into several classes, but that depends 100% on what it's for.

Thanks, So a class which contain few number of methods and large number of methods will be having same space ?

Yes it's a database access class. All the forms are referring this class. Do you know any applications that can count object utilized memory space ?

Yes - if you neclect the size the larger code uses in the dll. 20 instances of a class with 100 methods and no fields use exactly the some amount of memory as 20 instances of a class with no method and no fields.

I can't give you a link but I'd look for a Memory Profiling Tool.

Hi,
how to develop addins to MS Outlook thru C# windows applications?
Thanks,
Priya.

this is a very very abstract question Priya. No buddy's gonna tell u how to make the whole thing. try to be a bit more specific
|
|
|
|
|
What i want to know is are there any APIs or classes in C# which will help me create add-ins to Microsoft Outlook...say for eg. a new button in Outlook which would search for a particular appoitment in my Calendar...and things like that!! Let me know if this makes sense or any more details are needed.
Thanks,
Priya.

Hello,
You have to override "WndProc" in your Form.
Like this:
const int WM_SYSCOMMAND = 0x112;
const int SC_MOUSEDOWN = 0xF012;
protected override void WndProc( ref Message m )
{
if( m.Msg == WM_SYSCOMMAND )
{
if( m.WParam.ToInt32() == SC_MOUSEDOWN )
{
}
}
base.WndProc( ref m );
}
Hope it helps!
P.S.: Just cause I'm currious, why are you starting your question Subject line with "Re:"?
All the best,
Martin

I assume ths is ASP.NET ? Generate linkbuttons or just hyperlinks for the text in the row, and redirect to another page, with an Id on the URL so that page knows what record to load.

Currently, I'm working on COM Interoperability project. In that client application (in vb 6.0) need to launch my application developed in .net.
Now the problem is the assemblies referenced by my .net application is spread across 2-3 folders and not in the same folder where my .net executable is placed. Also, the client application is also not in the same path where my .net executable is. If I keep everything (i.e. .net executable and client application) in same location everything works fine but if I move my client application to location different than my .net executable path, client application fails to load.
I register the assembly into the registry withoug codebase. Also, I tried setting the private path in probing attribute in app.config file but it didn't work. I want to avoid making my .net component assembly as shared assembly.
Can any one pls help in how I can resolve the assembly reference issue?
Thanks...

Have a look at the AssemblyResolve event on the application domain AppDomain class. This event is called when finding an assembly location fails; you should be able to hook this and load the assembly from whatever location you like.
A quick google on that event gives a few examples.

Mark,
Thanks you very much for your reply. I was looking for some direction to resolve my problem which you very well provided.
However, Let me elaborate more on my problem.
In my case, there are two different applications, one developed in vb 6.0 (which acts as COM client) and other in .net. Now I register my .net application with registry (using regasm tool but without using /codebase switch). Also, I don't put my .net component (which COM client will access) into GAC. So in this case when I try to access my .net component from VB application using COM, VB application fails to locate my .net component and its dependancy. Can you tell me what I should do in order to make my vb application know where my .net component is placed.
If I put my vb application and .net application together, everything works fine. But if I put them seperately, loading fails with the message that "Runtime error '429'. ActiveX Comoponent can't create object.". In my vb code, I'm using CreateObject to create my .net component object.
-----------------
Private Sub Command1_Click()
Dim i As Object
Set i = CreateObject("TestApp.class1") (TestApp.class1 is my .net component)
i.ShowMessage
End Sub
-----------------
I hope I have explained my problem properly. if you have questions on this pls revert back.
Thanks......

Ah, sorry I assumed it was the .net client couldnt locate it's dependancies.
I'm a bit rusty on my COM skills, have you tried checking under HKEY_CLASSES_ROOT\CLSID to see if its been registered correctly? Otherwise you might have to use the /codebase option...
Good luck

Mark,
It seems now you have understood the problem correctly.
I can not use /codebase switch as my assembly is not strong named assembly (there are some issues because of which I can't make my assembly strong named). You can supply /codebase options only with the assembly which are strong named.
Thanks....

|

|

Hmmm if you can't use strong naming then I'm really not sure. Maybe someone else has some ideas? :/

If you'd bothered to read even a few threads down, you'd have seen another thread which already included this information. It's not hard to do - it just demands that you don't be so lazy when posting. Alternatively, there's a great tool that not a lot of people know about called Google which has nuggets like this hidden away.
Deja View - the feeling that you've seen this post before.

Hi
well I've been trying to transform an XML document using an XSL file I made and the problem is that the transform method adds these HTML tags in the resulting file as well which is what I dont want... Here's the code.
<br />
XslTransform myXslTransform;<br />
myXslTransform = new XslTransform();<br />
myXslTransform.Load(xsl_Path);<br />
myXslTransform.Transform(Xml_Path, "collapsed.xml");<br />
<br />
String target_Path=s_Path;<br />
target_Path=target_Path+"\\collapsed.xml"<br />
Object *oMissing = System.Reflection.Missing.Value;<br />
this.axWebBrowser1.Navigate(target_Path, oMissing, oMissing, oMissing, oMissing);
can u plz tell me how I can make the transform without having to add these html tags in the output.
Thanks in advance
