• Visual Basic StreamReader

  Hello, I’m trying to create a program will supply information for variables from a text file, so that as the possibilities change, a simple text file will need to be amended, rather than rewriting the original code. I am reading about FileStream and StreamReader, which seem like just the ticket. For instance, if I wanted to populate a TextBox with items I wrote in a text file, such as: Tom Mike Jim Jean I threw together a sub like this: ------------------------------ Private Sub Button6_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click Dim objF ...Show All

• Software Development for Windows Vista Workflow Serialization Problem

  Hi to all, I have been using beta 2 bits for a couple of days and trying to upgrade my project with the new stuff.

• Software Development for Windows Vista ParameterBinding loses Value in EventSinkActivity-derived classes.

  I have a workflow with one activity. The activity class is derived from EventSinkActivity. If I pass a value via ParameterBinding to this activity, I can get the ParameterBinding object by the string indexer in the Invoked event handler, but the Value property of the object is null. If I use EventSinkActivity -- instead of the class derived from EventSinkActivity -- it works fine. Is there anything I need to do in the EventSinkActivity-derived class so I do not the lose the ParameterBinding value Alek, Have you tried using the wca.exe tool, included in the SDK   Given a DataExchangeService interfac ...Show All

• SQL Server cannot open a jscript file

  SQL Server CTP Sept 2005. In Microsoft Visual Studio 8 after starting an Integration Services Project I tried to create a jscript file. A file was created but the browser was completely messed up. First I was never able to open it (right after it was created but not yet saved). The file name "jscript1.js" would appear as a separate tab on top of the window next to the "start page" but when you click on it the the file does not appear in the editor window as I assume it should. Instead the same object browset or start page would stay under the tab name "jscript.js file." Sometimes strange vertical stipes appear next to the tool box or instea ...Show All

• Visual Basic How to store Data ?

  Hi everybody, I'd like to ask you because I just can't decide with technology to use. I have a small application without a DBMS. But I need to store and provide some Data (Text). And of course I need to add, delete and edit all the Text. A Database would be great but I need something else. What else could I use XML Problem is I don't know much about the .Net XML Classes. And I also don't have much time to learn. TXT or CSV Is there still something else or what would you do it sounds like your best bet is to use a database...basically your other options are to use a flat file as you mentioned (xml,txt ...Show All

• Visual Studio Express Editions Data Source window disabled

  Hi guys, All of a sudden I got this problem about the Data Source window of VB Express 2005 IDE. Whenever I open up a VB form, the data source window doesn't show the corresponding dataset/tables anymore, but when I switch to the  form's code  the  dataset/tables  show  up. It used to show up whether I'm working on the form or writing codes. I can't  figure out  why.  The problem now is that I can't drag/drop the tables on the form because the data source window is empty. It doesn't affect the program and the other forms that I was able to drag/drop tables i.e. as Details or DataGridView before. Again ...Show All

• Windows Forms Invoke or BeginInvoke cannot be called on a control until the window handle has been created.

  This is throwing me for a loop. I have a modeless form open with a richtextobx. I am using FileSystemWatch to monitor changes on a text log file. When changes are found I check to see how much the file has grown, and then read and append the new portion to the RTB. The log watcher form comes up, does its initial paint (which is NOT driven by FSW) all is OK. Some moments later when the log file first changes, and FSW gives the event, I marshal it back to the GUI thread for updating the RTB, but get this odd error. I have done this pretty much already in previous VS.NET without a hitch. As far as I know my window handle has been created at the ...Show All
