All solutions are incorrect.
Correct code:
<br />
Excel.Range cell = (Excel.Range)m_workSheet.Cells[x + 2, y + 1];<br />
string st = cell.Text.ToString();<br />
Best regards, Alexey.

I hardly ever do Office Interop, but the Cell[,] returns a Cell, which has, IIRC, a Value property, soooo...
TextBox1.Text = xlsheet.ActiveSheet.Cells[i,1].Value.ToString();
might be what you're looking for, or something very close to it.

Hello all,
Does anyone know of any way of calling functions in a VB6 exe, from code in C#? Is this even possble? I don't know much (if anything!) about VB6 so I'm a bit confused. I've managed to call functions in a VB6 dll, but is the same thing possible with exe's too?
As always, any help at all would be greatly appreciated!
Thanks
Shehzad

Nope. VB6 .EXE's don't support export functions, so you there's really nothing to call. .DLL's on the other hand, you've already found out.
The only exception to this would be if the VB6 .EXE is an ActiveX Server, which has all kinds of exports, just like any other COM-based assembly. Just add a COM reference to your .EXE and you're just about all set.

Hi all, I'm using component WebBrowser in my Windows Forms application (Framework 2.0), thus I need to block WebBrowser shortcuts (such as F5).
When I set WebBrowserShortcutsEnabled property to false, all shortcuts are blocked, but also it blockes "Delete" key.
Is there simple way to block "F5" without blocking "Delete"?
Thanks in advance.
Best regards, Alexey.

Thank's for attention ! i've founded solution.
It's simple: use of event PreviewKeyDown:
private void OnPreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
{
if (e.KeyCode == Keys.F5)
{
e.IsInputKey = true;
}
}
Best regards, Alexey.

Try use Microsoft COM objects, like working with Excel or Word.

This is part of web development im afraid. Different browsers interpret HTML in slightly different ways and getting to know all the nuances of browsers is part of being a developer.
You often have to do some slight tweaks/hacks in your HTML, CSS and even javascript to get your page working as you are happy across all browsers.

hi all,
i have an application that i am trying to 'port' to be more usable by accessing properties via the prop grid in VS IDE.
i have a function in my component that needs two callback functions (which the component provides delegates for) which it calls in the owning application to get/set a string in that application, how can i allow the programmer to select these functions through the property grid?
if i set the type of the property to the delegate, the propertygrid makes it readonly.
i have provided sample bare code to illustrate the calling applications functions
i would like to move the delegate declarations into designer generated code.
public Form1()
{
InitializeComponent();
this.updater1.GetProductVersionFunction = new AutoUpdate.UpdateClient.GetVersionString(GetApplicationVersion);
this.updater1.SetProductVersionFunction = new AutoUpdate.UpdateClient.GetVersionString(SetApplicationVersion);
}
public static string GetApplicationVersion()
{
return "version";
}
public static void SetApplicationVersion()
{
}
}
any help please would be awesome.
kind regards,
g00fy

i would like to enumerate functions in the owning form, when the component is dropped into it and populate a ddl for each property with those functions in the form that match the delegate.
... or ...
when i type a name into the prop box the code is generate to create the function that matches the delegate.
i am googling but am coming up short.
kind regards,
g00fy

UITypeEditor is the answer. For every type you can define an editor which should be shown when it is edited in the property grid. Normally the property grid resolves one of the inbuilt ones which can edit the type but in case of a delegate it just doesn't find one. So you have to built one on your own. In general you 'just' have to inherit from UITypeEditor and mark the delegate with this class (Editor attribute)). This can become very tricky. I would recommend to use Reflector to look at one of the inbuild editors (DockStyle and DockEditor are probably a good one to start). You could also look into this[^] because it deals with this topic.
Edit: To be honest I never tried this with a delegate. I hope there are no limitations in regard to this. If yes you would have to provide a wrapper class for the delegate.

Not to sure, but I think the property grid relies on the existance of a System.ComponentModel.Design.IEventBindingService service. To do that u need to:
1. Implement the interface yourself.
2. Add it to the IServiceProvider
NOTE: if u doing this at runtime, then you will likely need to provide all the design time services yourself.

Hello
I want to make a program that can create and unpack a encoded '.rar' or '.zip' document.
I have found a dll to download from rarlab.com, but it will not allow to unrar files with password.
Does anyone know where an good article about using the encoded '.rar' and '.zip' documents, or does anyone know where to get a freeware dll which already contain the functions with pack and unpack files with password.
Thanks
QzRz

zip lib for .NET - SharpZipLib
And I never heard about free fullfunctional rar lib...
By the way, UnRar.dll supports extraction from password protected files. At least, my password protected rar archive was successfully extracted using sample solution, coming with unrar.dll...

Hi,
I am using Microsoft.Web.UI.WebControls.TreeView control in my application.
I am able to add new nodes and child nodes to it, but the problem i am facing is that i always get the selected node id as 0, i.e the id of the first Node.
All events have been written for it, autopostback property set to true, but am not able to access the selected node id. Even the event for the selectedindexcgange does not fire.
Due to this i am able to add child nodes only to the first parent node.
I am using a right context menu, and on right click on a particular Parent or child node, different operations like Add child node, rename and delete can be performed on it.
All this can be accomplished once i get the selected node id.
Can anyone please tell me as to how to proceed with this?
Thanks
