• Stark77 Problem with foreign key update

  Hello everyone, I am having trouble with a table I am trying to update. The table contains information about a client's cases, so it has a foreign key to the CLIENT.CLIENTID column. However, when a new record is created, the CASE.CLIENTID column is always blank. Note: I am using databound textboxes to show this information. I certainly don't want a databound textbox where the user has to manually enter the CLIENTID value for this particular case. So there must be a way to, before the commiting the new row to the list, setting this columns value, manually. After trying various ways to reference the new row's CLIENTID column, including using the BindingSource.AddingNew event, and trying to set the value manually into Bindingsource.Cu ...Show All

• brenzy Data Sources Window Is Inactive and Data Sources Disappear

  Can someone please help... I have been working on a project in Visual Studio 2005. After changing some of my data sources in the Data Access Layer, all data sources disappeared in the Windows UI layer. This was all working fine until I changed data sources in the DAL and built the DAL project. This is the third time this has happened. I have rebuilt my laptop from scratch, reinstalled Visual Studio 2005 clean and tried all kinds of other things including scraping my whole project and starting over. Everything seems to work for a while until I start making changes to the schemas in the data layer. I have seen a lot of older blogs and posts on this issues but none recently for the production version of Visual Studio 2005. I am using ...Show All

• Shane Fatzinger Evaluate a string expression

  Say a textbox's text is (3*4) / 2 How could I evaluate that Or evaluate whatever is entered in the box If possible I want the result to be of type Decimal Thank you. To do this you need to write a parser. All that huh So I would have to write my own string parser Is there a link with a tad bit more information When you 'parse' through something, in this case a string, you will be taking each character/word/line and doing something with each recognised value. So, you create a routine which splits the line into characters and you walk through the characters doing something with each one. This often results in a loop, a lot of case statements, and If/Then statements. This is a parser. Google has a lot of links ...Show All

• ndroe Slow picturebox hover

  I'm rather new at Visual Basic and a problem has accrued. The problem I got is that the change of image in the picturebox is slow, to slow to be acceptable.
