I'm developing an application which relies on several files to be copied over to a specific location on the users hard drive ("C: est") when they run the program for the first time, and am having a hard time wrapping my head around how to account for the fact that the original location may be in a different location for each user.
Any ideas for either getting the path where the files would be and then copying them to the desired destination?
How to create a dynamic report?
View 1 RepliesI am trying to generate a report using Crystal studio that takes a public variable from the vb.net application. I think the best way to do it is to just dynamically give the filter to the report at runtime, but I can't figure out how to set it up to take any information at runtime.

View 4 RepliesOn runtime about the number of columns to show (mainly remove columns that are available and then shift the remaining columns).. I can view the reports in a report viewer normally all I need is to be able to edit the columns in run time.

This for a semi-automated application. Basically the user provides a list of parameters (entered as an offline spreadsheet). The application automatically selects the required report and logon information. Each line in the given spreadsheet will be used as parameter values for a certain report.Therefore the requirements for this (vb.net) applicaton include:
- dynamically select a different Crystal reports
- each report may read data from different tables from an Oracle database.
An old application of mine that had done something similar and it works normally. Those Crystal reports retrieve data from a SQL server stored procedure. (The stored procedure reads data from Oracle using linked server concept). I do not have to set the logon information dynamically in the vb.net code because every report uses Trusted Windows logon concept. The application can also pass dynamic values to different Crystal report parameters without problems.Then I modify this old application for the required new set of Crystal reports. Because these reports access Oracle database via ODBC and not every report reads from the same Oracle schema, it appears I have to write codes to pass ODBC Dataset and its logon information (the users do not want enter it everytime). The application does not run after the change. The report printout shows blank. Although I can accomplish what is needed by modifying each report to use Stored procedure. But this is not prefered and not a simple task because of the number of reports.I have tested each report and it does run normally in interactive mode.I am not sure if I need to write codes to set the datasource for these 'new' Crystal reports. In my test codes I set the reportsource for my CrystalReportViewer object to an non-typed report. Is there anyone who can show me sample codes that
1) achieve odbc logon
2) select a report dynamically for preview/printing
3) pass values to parameter
Is there any way to set the crystal report data source location to the application.startup-path?
have a nice day

directly here is the issue:a "OpenFileDialog" on a windows form is made to choose a picture and then insert it into a rdlc report under VB.net 2008 so i need the exact command to access any picturebox in the rdlc report.

how I can reference a report variable in the Report Properties Code Window of a local report? I have tried Variables!Claimant.Value (for a variable called Claimant) but I get an error "Reference to a non-shared member requires an object reference." I have tried qualifying it with Report. and also with the report name in front of it but I get errors with this also.I have the variable CLaimant defined in the Variables section of the Report Properties.

Well on to my question that I wasnt able to find out exactly using my search. What I want to do is use opendialog to select a location to an access database and then take that location, and use it to update my connection string db location. Would it be possible to edit the path at runtime like that using an opendialog? Also, if that is possible, would it be able to save that location to the program so that I wouldnt have to be edit again. The reason why I just dont hardcore the location into the database is because there will be many different computers that the program will be installed into and the person I am making this for wants the flexibility to move the database around at will.
I am using the following code to establish a database connection to my datagridview and Access database. Here I am giving my file path name to the connection. This code works fine only on my computer. To make this code run on another computer I need to change the database pathname in the code. Is there anyway I can make this connection dynamic so that I can make this program run on any computer

View 2 RepliesI am looking to make a database call based on user input. The line I am using is:general_read.CommandText = "SELECT * FROM general WHERE Business_Name = '" & business_name & "';"
business_name is dynamically loaded from:Protected Sub btnLoad_Click(sender As Object, e As System.EventArgs) Handles btnLoad.Click business_name = txtName.Text
[Code]...
The error that is being shown is: Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.I'm assuming it has something to do with the variable not being set before the database call is made, but I'm not entirely sure.

View 7 RepliesI'm trying to construct a database driven VB.Net app that pulls a list of registered accounts from a database and displays the usernames of throes accounts in menu, so the user can select one and a new form open (where they work with it).what I have so far is the constructor for the MDI parent window.[code]What I want to happen is when a user clicks on the context menu a new MDI child form is created and the data in user is passed, however because AddressOf doesn't like passing data this doesn't work.I've looked at delegates and landa expressions but don't think either of them do what I need, the other option is to make my own subclass of the ContextMenuStrip class, which 1) handles the clicks the way I want to and 2) sounds like a nightmare.Before I launch into what I think will be a hell of a lot of work, am I missing something? is their a simple way to do what I want to do? or if not will sub-classing ContextMenuStrip work and if not any ideas as to what will (and if it will, any ideas as to how to start learning how to do that)
