Make the file read only ?
I don;t know that Word allows you to add images that then can't be removed.

Hi
When we sign assign the document with certificate there is a image or may be a control shown that is unselectable and undeletable. My interest only to get that type object.
Thanks

I have an application that uses Excel 2003. How can I know what is the version of Excel in the end user? Is there any way I can find it out when the program starts?
Thank you in advance

And option could be to find out where/ if Excel is installed on a machine via the registry.
Then open the fileinfo (use Diagnostics.FileVersionInfo and FileVersionInfo.GetVersionInfo(strPathToFile)) and extract the excel.exe file version.
Based on the result of that, you will know what excel version the user has.

I see two problems
1 - you set a connection string but don't use it
2 - you don't specify a data source ( although it looks like it's SQL Server )

I don't understand, how do you expect this to work without a connection string ? you have what looks like one, but it's not used anywhere. How did you come up with this code ?
Here[^] are the docs for the SqlConnection class. Basically, you need to pass in a valid connection string to the constructor.

Thats the million dollar question that comes to my mind lots of times when seeing something like this.
I am not saying the OP did this - but many times people just copy paste some code and when it does not work as expected, they post it verbatim in forums to get an answer.
I can understand if the problem was related to say, Graphics, drawing or some bit shifting etc., but something fundamental as database handling needs to be learnt and not copied.
Thanks for listening, I needed to say this sometime.

Forgive me I am somewhat of an amature programmer.
I have created a simple VB application which consists of a form with various values displayed and an "update" button. I would like to be able to up date the values by hitting the push button. However, what I would like is to extract data from an excel file stored on our system somewhere. The excel file is updated periodically but when I hit the button on the VB form I want the latest data to be captured and displayed.
Any ideas?

There's a toolkit from MS for talking to Office from .NET.

I will also post this in ASP forum. I have a general question. I want to create a "webbased, interactive, and collaborative classroom learning tool". I believe ASP would be a good language for this. However, I also have a strong need to become proficient in VB. My application will be a type of question and answer game to be used in the classroom.
Here is my question; If I first build it entirely VB.net as a VB application, how easy is it to then move it to the Web using ASP?
You can tell from my question, I am not an expert in either or I wouldn't be asking. I know some VB but no ASP. I have six months to work on this so I am somewhat confident I can do whatever needs to be done.
Thanks,
Jinx

asp is ALWAYS a disaster. ASP.NET is a far better choice.

Oh, you mean ASP.NET ? Virtually impossible. The web and windows are two different worlds, with different UI controls and paradigms.
What do you want this tool to do ?

Thanks for responding. Yes I do mean ASP.net but it doesn't sound like it will be a good choice.
The application will need to do several things. The easy way to think of it is to imagine the Jepardy game being played in a classroom. It can't be exactly like Jepardy because of copy writes and legal issues. The game would be hosted via the web but the only competition would be within the classroom. In other words, one class would not compete with another in a different location. The game would need to do all the typical things a question/answer format requires. Points, levels of questions, teams, history etc. Here is the unique part, the content would be collaborative from teachers and professors anywhere. For instance, a physics teacher could build game content based around a subject and then use if for their class. However, another teacher, anywhere in the world could take a look at what the first teacher did and use and/or modify it for their class. This means there will need to be a database on the server and and user friendly interface to build content to update and store all the content.
Seems like a lot to me but I would start modest and add feature as I go. Since I need to learn the VB.net for my employment perhaps I could use it as a prototype of sorts. You say there is no conversion path from VB.Net to ASP.net so I would have to rewrite it. Perhaps it should not be in ASP.net? I am not locked into ASP.net like I am VB.net. Any suggestions on what might be a better language for the web world?
Sorry to be so long on the explanation.
Thanks, Jinx

Well, the UI you would have to rewrite. Not the business objects, if you structure it properly.
Keith Jenkins wrote: Perhaps it should not be in ASP.net?
It sounds to me like ASP.NET would be a likely candidate, you don't need the form to do anything apart from respond to events, right ?
Keith Jenkins wrote: Any suggestions on what might be a better language for the web world?
C# and VB.NET are a direct tie, because ASP.NET is the best way to write websites that I know of.

As Christian says, best to move straight to VB .NET/ASP.NET.

It depends how well-designed the desktop version is. Rocky Lhotka's business objects framework (CSLA.NET - http://www.lhotka.net/[^]) is about this kind of thing. However, his framework is big and complex and is aimed at enterprise apps.

On the Y axis of a graph, if the graph starts at 0 and goes to 10000. Is there a way you can force the graph to display the Y values to include a comma so that 10000 renders as 10,000.
Thanks

use format string like this:
Dim cnt As Integer = 100000
MsgBox(cnt.ToString("###,###,###"))

Thanks for the reply
Here is the code that I used to get the formatting I wanted.
With .Grid.AxisY
.AxisMode = AxisMode.ValueLinear
.AxisScale = AxisScaleType.UserDefined
.LabelFormatMask = "###,###,###"
.GridLinesOn = True
.GridLineProperties.Color = Color.DarkGray
.MaxAxisValueUser = highest
.MinAxisValueUser = 0
.TickMode = TickMode.OnStartAtZero
.MajorTickInterval = 5
.MajorTickCount = 0 'If count is nonzero, interval is ignored
.LabelProperties.Font = New Font("Tahoma", _
8, FontStyle.Bold)
.LabelProperties.Font.Dispose()
End With

I don't get why so many people ask this. Choose a project based on your skillset and your needs, we can't really answer you.
