If your reports are taking 7-8 mins to load, it's more likely to do with your query/stored procedure that is selecting the data... how many pages long are your reports? Are you loading a full set of data then using Crystal to filter records? This will be monumentally slow if you are...

1 page per report but there are 2 - 3 subreports on every report and different has tables.
Report1 → subreport1 →table1
--------→ subreport2 →table2

no, i just create a working table then load on that report. i did not use storedprocedures.

I am trying to create a dictionary in Visual Basic 2008.
I have a list of words in a text file and need to get the definitions for them.
I am trying to make a program which reads the text file, line by line, taking out the words.
Then I want it to go to "http://dictionary.reference.com/browse/" and download the definition only, without adds, menus, etc.
Then I need it to save the definition, line by line, into another text file and repeat the process for each word.
So far I have got the opening and saving part sorted but I have no idea how to isolate the definition and download it.
I have googled it but couldn't find anything helpful.
All and any assistance is appreciated.

You'll first need to download the page[^]. Then you'll end up with a HTML-page in a string, or a file. Then you start stripping everything that you don't want. That could be done via regular expressions, or the string-handling routines from .NET.

Hi Everyone,
Here is an interesting problem. I am trying to add an expression column to a dataset that already contains data. The expression involves coverting the string data in a specific column into numeric data.
The MS help system says I should use the following example to perform this operation: myDataColumn.Expression="Convert(total, 'System.Int32')"
In having incorporated this into my code, I get the following error:
"Input string was not in a correct format."
Here is the actual code:
Dim tmpCol As New DataColumn<br />
tmpCol.DataType = System.Type.GetType("System.Single")<br />
tmpCol.AllowDBNull = False<br />
tmpCol.Caption = "nResult"<br />
tmpCol.ColumnName = "nResult"<br />
tmpCol.DefaultValue = 0.0<br />
tmpCol.Expression = "Convert(Item01, 'System.Single')"<br />
<br />
tmpDS.Tables(0).Columns.Add(tmpCol)
I have tried several different ways of using the Convert function, but nothing I've tried works.
Has anyone else had experiences with using the Convert function that might help???
Thanks,
cb
Additional Info:
1. The column, Item01, in the tmpDS dataset is a varchar field that contains only numeric data.
2. The tmpDS dataset is obtained from an XML data file.

Perhaps if you told us what happens when it 'doesn't work' ???

OK, so the two possibilities are that your filter is wrong, or your input includes values that will not convert to a single. Have you checked the input ?

Yes. I've checked the xml file and all of the values in question are either numeric or null.
I've tried using the 'System.Int32' conversion definition as well and received the same error; thinking that perhaps the 'System.Single' might be incorrect.
I'm wondering if there isn't some issue with adding the new column to an existing dataset already containing data.

I'm having consistent crashes when accessing the solution property screens (application, compile, debug, etc tabs).
So if I open solution, and I double click My Project (which opens up the config screen), VS just immediately dumps out. If I reboot, the solution(s) start acting normal again. Just annoying.
Has anyone else run into this? Any idea what causes it? Once the crashing starts when double clicking "My Project", a reboot has to be done to prevent the crashing. At times, that can be a pain in the ......

I've had that happen once or twice. I solved it by navigating to the project folder in Explorer, enabling the "Show hidden files", finding and deleteing the myProject.suo file. Launch Visual Studio and open your project.

That did it. Thanks Dave!

Does anyone know how to install an application that you created on another computer using a disk or any other method? I clicked publish, distribute on a CD rom, then when i try to install it on some computers there is a message that pops up saying
"Unable to install or run the application. The application requires that assembly System.Core Version 3.5.0.0 be installed in the Global Assembly Cache (GAC)"
Does anyone know what that means? It only happens on some computers, some are able to install the software. Is there anyway to install the program without needing that GAC thing?
Thanks

Hi,
System.Core 3.5.0.0 is part of .NET 3.5 which seems to be a prerequisite of your app.
There are two ways to go now:
- maybe you don't really need .NET features beyond .NET 2.0 and could rebuild your app for .NET 2.0, giving it a much bigger probability of running on modern PCs (you can choose the target .NET version in your project settings);
- or you keep the app as is, and make sure .NET 3.5 is installed; creating an installer would allow you to check for that automatically.

Hi Everyone,
I have created one button in VB .net which on click creates a backup/copy of my sql database file, i.e. client.mdf file, into a separate folder. The code is like this:
Private Sub Button_Click()
Dim dbdlg As New FolderBrowserDialog()
con.Close()
CurrentDatabasePath = "F:\..\client.mdf"
If dbdlg.ShowDialog() = Windows.Forms.DialogResult.OK Then
Dim pathtobackup As String
pathtobackup = dbdlg.SelectedPath.ToString()
File.Copy(CurrentDatabasePath, pathtobackup, True)
End If
End Sub
The error I am getting while executing File.Copy statement.It shows :
The process cannot access the file 'F:\...\client.mdf' because it is being used by another process.
Can someone tell me how to resolve this error? I think I have to detach the database, if yes, how?
Thanks
R.S

You can't make a copy of the .mdf file while SQL server is running. Instead of trying to copy live database file, why not try running a TSQL query to backup the database to a separate file and then copying or moving that?
The SQL required looks something like this:
BACKUP DATABASE MyDatabase TO DISK = 'C:\Temp\MyDatabase.BAK' WITH INIT;
Now you can just write some VB code to shift the newly created .bak file.
Hope that helps!

Hi,
Can you pls elaborate how to do this?

1) Run the TSQL backup query on the database that you want to back up
2) MSSQL will create the backup (.bak file) in the location you specified in the query
3) Run your VB.net routine to copy or move the .bak file to the location of your choice

Hi
I have a function that returns the connection to DBASE server.
I use this function to connect to the server.
When I use for testing with the .mdb database, the connection is set and application worksd fine.
When I use the server address in Data Source to connect, the application is exited.
I dont understand why this happens.
Any help on this will be very much helpful.
Thanks in Advance.

Are you getting an error message? If so, it would be helpful if you could include it.
So you're saying that is works when you use the bottom connection string, but not when you use the top one? The top one doesn't have the .mdb extention, is it supposed to? Does the user have access to that network path? Is that database protected by a username/password that you forgot to include?
Hope these suggestions will help you find your answer.

Yes, works fine for .mdb file.
There should'nt be a extension for DBASE database.
User has access to that path.
there is no username/password for that drive.
