Crystal reports Problem in vb.net2005

28-Feb-07 9:02

if you're using VB6, try the following:

Select Case cmbLetters.Text
 Case "A"
   lTemp = 10
 Case "b"
   lTemp = 8
 Case Else
   lTemp = 0
 End Select

(where cmbLetters is you ComboBox)

Sir/Madam,
I have two records in my database.From the form , I am chosing the id and want that record to get displayed in the crystal report.There are two tables in the database and there is a primary and foreign key relationship between them.Now the problem is , both the records are comming.I have created links between both tables in the reports.Is there any way to create the crystal report dynalically or can i pass the parameter to show the report.
Parameter means that id which has primary and foreign key relationship.
But I don't know the code how to pass the parameters.
and parameters should be passed at both ends (I mean in the crystal reports as well as on the coding side)??
I don't want to generate the window that ask me which id u want to select .
Please help.
Thanks and regards

In Visual Basic, data can be converted in two ways: implicitly, which means the conversion is performed automatically, and explicitly, which means you must perform the conversion.

Re: how to add click event on button twice?

You have to do a two states button, either using the text itself to identify the current state or by means of an auxiliary variable.

For instance:

(1) If myButton.Text="ON" Then myButton.Text="OFF" Else myButton.Text="ON"

(2) IF bIsON = True Then
       bIsON = False 
       myButton.Text="OFF"
    Else
       bIsON = True 
       myButton.Text="ON"
    End If

where,of course, bIsOn must be a variable of the Form (or a Static one inside the event handler).

You don't add the event twice. You haven't given enough detail about the problem to describe an accurate solution. Where is this text comming from? How is it stored? Change the text to what?

Opening .dll's

I have been given a project which was developed by someone who has just left our company and is not contactable.
He developed the project and put it live but didn't save a development copy. The live version doesn't contain the .vb files
and just everything is saved and compiled as .dll.
Does anyone know how I could open the .dll filesd to see the .VB code??

Too bad! Regards to the developer!!!

The only way to get the code now is by decompiling the dll's. Painful and time consuming. Besides the result might not be what you would expect.

So your best bet is to bribe the developer for the code, or better yet redo the app.

The perfect code is always in your head...it just a matter of how hard you bang your head against the wall to get it out!

If Iam giving thru the suggestion given by you,

Add a table to the dataset then in columns tab in this table add the number of columns u want. then in the grid put the datasource = the dataset and dataMember the table u have just created.

Then I will get all the data into the grid.but I want limited columns data i.e. only one or two columns/fields from the whole table

How to Set an Application Path in VB.Net

28-Feb-07 21:50

I suggest u change ur select * statement in ur stored procedure to select column-name. Then u will retreive only the specific column(s) u specified.
I.E. create ur adapter based on a select column-name & not select * then genertae the dataset and put it as data source for the grid.
Hope that works cause i cant think of any other way right now.

Hence you want to know the application path; then use
Application.StartupPath.

You don't set this path, you retrieve it. The equivilent in VB.NET is Application.StartupPath.
