now, i have a problem in programed a network application. Have anyone can help me? The problem is that I need to open a powerpoint file in my program and send it to everyone in my network. Someone talk me that you can't embedded a powerpoint file in your program. Is it right? So, I think it may have another way like open an powerpoint than share the powerpoint to everyone in my network. But I don't how to share an application in C#. Please tell me. Thanks a lot...

PowerPoint is an application required to view PowerPoint presentations. Even if you embed it in a .NET application (written in C# or whatever other mangaged language), PowerPoint is still required to be installed on the client's machine. The installation source can be located on a network share, but it still needs to be installed on the client machine.
And, yes, actually you can embed the PowerPoint Viewer in a .NET application, but that too would need to be installed on the client's machine. This is how COM works (basically).
If you don't have PowerPoint available to all your clients on a network, you can download and install on each of their machines the PowerPoint 2003 Viewer[^], which can display PowerPoint slides from version '97 and newer (up till at least 2003).

Hi all,
I am trying to build OfficePlanSample (a VISIO SDK sample found at:
C:\Program Files\Microsoft Office\Visio11\SDK\Samples\Office Plan\CSharp. )
I get the error:
Microsoft.Interop.Visio.Application does not contain a definition for 'Name'
???
I have added all needed references as far as I know.

I already answered this one, presumably from you (get an account already). See http://www.codeproject.com/script/comments/forums.asp?msg=787915&forumid=1649&Page=1&userid=46969&mode=all#xx787915xx[^].
If you are the same person, you need to create the ActiveX interop assembly by customizing your toolbox (right click, select "Customize...") and selecting the COM control from the COM tab. Drag that into your project.
The Office 2003 PIAs for VS.NET 2003 are for the various object models, not the ActiveX controls. The ActiveX control wrappers (which inherit from System.Windows.Forms.AxHost) will be created when you drop a COM control on your form or other container control.

Ok, I did that.
Is that suppose to fix it so it compiles?
I do have the control on the toolbox.
It doesn't compile!
Sorry if this is a newbie question, but I still can't make it compile....

The problem is that you need to use the Office PIAs (Primary Interop Assemblies) and DO NOT generate these yourself. If you need to import an ActiveX control, once you get the right COM control on your toolbox, drag it to a form or other container control in your project. This will create a different kind of interop assembly - the only kind you should generate.
If it doesn't compile, you should provide more information about the exact error. There's an infinite number of reasons why something might not compile.
Also, please register for an account. It's quick and it's free and there's many people who go by the name "Anonymous" so it's difficult to know if I'm talking to the same person all the time.

thank you very much.
I have fixed it tho', and it was the version of office and visio I had on my laptop! I had Office 2002. Just by installing Office 2003 and Visio 2003 the compilation is perfect, with no changes on my part.
Thank anyway.
I hope this information is useful to other people.

I have Microsoft Visio 11.0 Drawing Control in my toolbox, but how do I get Visio controls there????
I mean, the elements to draw a UML graph, for example....
|
|
|
|
|
You'll need to read about the object model on MSDN[^]. There's also several articles on working with the Visio control.

As I suspected, you were trying to use the new PIAs more than likely. If you use the Office XP PIAs, you should be able to work with both Office 2002 and Office 2003 since following COM guidelines can help ensure then COM interfaces are backward compatible, which Microsoft does a pretty good job of doing (since they wrote the specs).

I'm working with DataGrid in winforms application. I need to set focus() to a specific cell in the DataGrid.
I used the CurrentCell property to set the cell focus:
private void ColumnChangingHandler(object sender, DataColumnChangeEventArgs args)
{
switch (args.Column.ColumnName)
{
case "acsID":
{
string value = args.ProposedValue.ToString();
if (!IsNumber(value))
{
SetCellWithFocus(this.dataGrid2);
dataGrid2_GotFocus(sender, args);
}
break;
}
}
}
private void SetCellWithFocus(DataGrid myGrid)
{
myGrid.CurrentCell = new DataGridCell(1,1);
}
private void dataGrid1_GotFocus(object sender, EventArgs e)
{
MessageBox.Show(dataGrid1.CurrentCell.ColumnNumber +
" " + dataGrid1.CurrentCell.RowNumber);
}
but the focus was returned in the next cell.
Please help me.
Thanks

I don't have VS.NET to test it now but it seems it is zero based.

How do we get the current path of the application?
|
|
|
|
|
Use the static property StartupPath of the Application class.
|
|
|
|
|
Simply: Environment.CurrentDirectory. Its a string so you can feed this to other objects like DirectoryInfo and Directory.
|
|
|
|

While I'm sure you probably mean what the other reply suggested (Application.StartupPath), "current path" is not always the same directory as the application. It is the current working directory, and can be set on shortcuts to something different, or if you are in a command prompt in a different directory and type the path to the application. The directory you're in is the currenty working directory. It's important to be mindful of this fact.
To get the current working directory, you can get the Environment.CurrentDirectory. If you want the application directory to be the current working directory anytime your application starts, set this property like so:
Environment.CurrentDirectory = Application.StartupPath;

Need to create and use custom attribute in Active Directory user account via LDAP.
Active Directory server works on Win2003 Enterprise.
How I can do it?
Thanks.

The articles that Mazdak's search lists don't explain how to add a custom attribute to the Active Directory schema, which is what you appear to be asking. For information on that, see How to Extend the Schema[^] on the MSDN. To get this schema extension attribute, you can use its name in the DirectoryEntry.Properties dictionary property.

I have a class that is so long that I would like to split it into two or more files. Like keeping public methods and properties in one file and private methods and variables in another. Possible ?

Not yet. The functionality for this will be available in the next release though. (So, it looks like you'll have to wait a while)
