19meg!!! Does XP have this already? Is it in the Service packs for Win2K? Is it really worth moving to C#. Is it free to distribute on CD with a C# app?

.NET or not .NET? MFC is the question......

XP doesn't have it yet.
The last service pack for Win2k doesn't have it.

I don't know of any Microsoft applications or products that distribute it yet - apart from Visual Studio.

I would expect to see it in a service pack soon and probably in the next version of IE.

Hehe lets hope so. It also seems that .NET server has it already and will have it. On my beta it has 'The .NET Framework' however I have not dabbled in that realm as of yet.

.NET or not .NET? MFC is the question......

Popup styled window

Trying to create a custom listbox control, but have run into a roadblock here. The popup list cannot be made to float as the common control's version does. Is there not some style to be applied to a window resulting in not being clipped by its container? The framework is obviously capable, looking at the menu component and the dotnet combobox, but I need to know where to look.

I know several functions:
- atof - converts to double
- atoi - converts to int
- _atoi64 - converts to __int64
- atol - long
or function from Shell API
- StrToInt - you must attach SHLWAPI.LIB library to the project

I don't know if they exist in C#. Try them.
Good luck

for any conversation i use System.Convert.

Example:
string str = "555";
int i = System.Convert.ToInt32(str);

(also you can use ToInt16(), ToInt64() ...)
See System.Convert for additional Information.

Selecting from listbox with right mouse button

If you left click on a line item in a listbox it selects the item. Clicking the right mouse button is detectable in the listbox but does not select the item. Is there a way to override this listbox behaviour and select an item with the right mouse button?

override the MouseDown Event from the ListBox Control:

private void listBox_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
if(e.Button != MouseButtons.Right) return;
int nIndex = listBox.IndexFromPoint(new Point(e.X,e.Y));
if(nIndex != -1)
listBox.SetSelected(nIndex,true);
}

Accessing Word Documents in C#

1-Mar-02 8:41

I'm creating a program that will pull information from a SQL database and map those fields onto a Word Document.

The Word Document is formatted with bookmarks so you can easily reference to the part of the document you wish to append to.

I know this is possible in VB and Delphi 6; however, I've found nothing in C#.

Has anyone experimented with this? Or do you know where I might go to find some more information?

Thanks guys,

Hi All,

I am trying to find out if we can connect a C# Application to a website and view some details as in, how many sessions are open and what there SessionID's are.

Things like that.

Would this be possible?

Thanks

To get the messages you can override the WndProc method on your Control/UserControl/Form.

protected override void WndProc( ref Message m ) {
  switch(m.Msg) {
    case MY_CUSTOM_MSG:
      // do stuff with the msg
      //   LPARAM = m.LParam
      //   WPARAM = m.WParam
      //   Place any result value in m.Result
      break;
    default:
      base.WndProc(m);
      break;
  }
}

That should be the basic look of it.

HTH,

resource files in VS .NET

Hi guys, simple question, how do you use resource files in C#? For example, suppose I create an icon using the editor in VS .NET and the file is named icon1.ico, how would I the go about referencing that file from my code? Currently I keep getting file not found errors (during debugging) because it seems the system checks for the file in the bin directory (I think). Also, what is the best way to set up a repository of resources for my project? For example, if I have alot of different icons that I would like to use dynamically in my app, how would I set that up?

Regards, Senkwe

In VS.NET click on your icon in the Solution Explorer then in the properties box change the Build Action to "Embedded Resource".

Now when you build your project you can get a stream to the file from the assembly.

System.Reflection.Assembly asm = GetType().Assembly;
System.IO.Stream = asm.GetManifestResourceStream("myDefaultNamespace.myFolder.Icon1.ico"));

The string that is passed in is a tad difficult to understand at first.

myDefaultNamespace is the namespace that is assigned by default to new classes that are added to your project. You can see what this is by going into the properties for your project.

If you create a folder within your project and place icons in there, then you also append the folder names to the namespace (if you haven't noticed it -- when you create a folder, any classes created inside that folder have the folder name appended to the default namespace); finally append the filename.

In the example above i have an icon named Icon1.ico located in a folder called myFolder in my project with a default namespace of myDefaultNamespace.

It is possible to set the default namespace to nothing, in which case you use the folder (if any) and the filename.

HTH,

James

Is it possible to lock the first column in the datagrid control (Windows Forms version) so that it can never scroll off the viewable area? Similar to the way Excels 'freeze panes' feature works.

How to make custom/own BASE classes

Hi
I have a new class witch I want to make "public" for the .NET framework, I have tried to use the "gacutil", but when I try to compile a new calls file using my "namespace" it fails.

Thanks

To use an assembly that is in the GAC you still must reference the assembly. What seems to be a pain is that you can't just reference it and let it find it in the GAC you have to specifically tell it where to look for your assembly.

What I did was I made a copy of my assembly and placed it in the same directory as my source, I then added a reference to that (using VS.NET or the /r: compiler switch). Once the code is compiled (and the assembly is in the GAC) you no longer need the local copy of the assembly.

Now when you run your code, if the assembly isn't located in the current directory it will search the GAC for it.

HTH,
