The problem I see is that your call CreateSubKey on a key that already exists, it won't return an object that SetValue can be called on.
Seperate these calls into seperate calls. Don't chain object call onto object call. Verify that you actually have an object before you make a call on it.

Thank you for your reply.
In my case it works the same, but you're right.
It's syntactically correct to check if the key exists trying to open it.
But the problem remains.
After the modification of that keys, the extention continues to open the old program.
Any other idea?

After running this code, open Explorer and see if the change was made in the File Extensions, under Tools->Options.

You'll havde to contact SAP support for this one. Since SAP took over BusinessObject, none of the links for CR merge modules work anymore.

Hi,
I have a Crystal Report document which contains a parameter field. The parameter field is set to allow multiple values. In my VB application I have an array of strings which I want to pass to the Crystal Report parameter field. I have tested the report from with Crystal Reports application using the values contained within the array and the report works fine which leads me to believe that there is a problem with my code. The problem being that when the report is displayed, only the last item in the array seems to have been added to the parameter list.
Here is my code for adding the contents of the ArrayList to the parameter:
Dim crParameterDiscreteValue As ParameterDiscreteValue
Dim crParameterFieldDefinitions As ParameterFieldDefinitions
Dim crParameterFieldLocation As ParameterFieldDefinition
Dim crParameterValues As ParameterValues
crParameterFieldDefinitions = crReport.DataDefinition.ParameterFields
crParameterFieldLocation = crParameterFieldDefinitions.Item(strParameterName)
crParameterValues = crParameterFieldLocation.CurrentValues
For Each strParam As String In arrParameterValues
crParameterDiscreteValue = New CrystalDecisions.Shared.ParameterDiscreteValue
crParameterDiscreteValue.Value = strParam
crParameterValues.Add(crParameterDiscreteValue)
Next
crParameterFieldLocation.ApplyCurrentValues(crParameterValues)
Any body have any ideas where I am going wrong? Thanks in advance.
(BTW: Using VB.NET framework 2 and Crystal Reports 11)

Hi,
I wrote a usercontrol based on a picturebox. It reprecend 2 textboxes on a scare but diagonal separated. How can I give it focus; i already tryed
control.focus but becourse it is a picturebox (i think thats the reasen)it wont work.
Jan
if someone has another/beter idee thats also welcome
|
|
|
|
|
A PictureBox is not a control that holds an editable value. This means that it's only there to display things, and that's why it can't get focus.
Is there a reason why you are bound to a picturebox, or can you swap it for a UserControl? You can set a background-picture on those too, if I'm not mistaken

Hi to all,
in my vb.net project i have so many flash files within the form (using axShockwave)
Currently I am running them by giving the full path.
But to make it run after the installation of my project also, what need to be done with the file path? I know I have to use application.startpath. But to which folder should I copy the files. and what should be the path exactly?
Same way can I do for my Crystal report files too?
Thanks a lot in advnance
I am a beginner

Now, there is a bit of a clue in the name application.startpat. Could it possibly be where the application starts from? Which is where you have installed it.

Then how is your mail supposed to get out into the world?? Without SMTP servers, you're pretty much out of business. Every library I've ever seen uses an SMTP server.

Rajeev Dhiman wrote: I mean, like .Net SMTP Component uses local SMTP Server
It uses whatever SMTP server you tell it to use, but it MUST use one. Every component/library I've seen requires an SMTP server somewhere in order to use it.
Rajeev Dhiman wrote: there are some alternates like chilkat components
It still has to put it's mail on a server somewhere (using SMTP) in order for the client to pick it up.

Look into Microsoft's Virtual Earth SDK. It might do what you want, but I don't know for sure, because I've never used it.
