• Visual Basic Getting the last number of a column

  How can I get the last number of a column in a certain table of my database.I had a form that was bounded to this table that has an autonumber field.To be able to add another record and automatically add the autonumber, I want to get the last value in the table to be able to increment it by one when i click the add new button.thanks.... An identity column adds itself, by definition. You can do a select TOP(id) to get the highest number there, or if you were to write your insert as a stored proc, you could have it return @@IDENTITY, which would be the value you inserted into the identity column. ...Show All

• SQL Server Execution of Package failed

  I am trying to design package which would copy all tables and stored procedures from one server to another. It used to be simple task in SQL 2000, there was wizard. However the new wizard does not work... I wrote SSIS package, but when I execute I get the following error: "Can not apply value null to property Login..." Any idea It seems to me that this new SQl2005 is not that simple to use like 2000. 2000 was a great product. I am considering to rollback to 2000. Very frustrated with the new one...          There should be more to the error message than that. Please can you copy the ...Show All

• Visual Basic How to determine the SERVER.TRANSFER'ing aspx page.

  Hello, I'm wanting to know how to determine the page that was just transferred away from.  For example given three web pages; CallerA.aspx, CallerB.aspx, and TargetC.aspx.  Both CallerA and CallerB can perfrom a 'Server.Transfer' to TargetC.  TargetC.aspx which needs to appear differently based on where the transfer came from.  TargetC also uses properties from the calling page in order to retrieve information from that page.

• Visual Studio Team System Hot to plus two numbers in DOS-Command?

  There is needed for an auto-incrementing version number in my software build process. I want to place the version number(like 2.0.3.6) in a .txt file, and the txt file just has one row. Now i want to know whether it can plus two numbers in DOS-Command and return result Thinks! No, you cannot do this using DOS command. You will need to write a Task of your own. There is Math.Add at http://msbuildtasks.tigris.org/ which may do what you are looking for. BTW, there is MSBuild/Team Build sample task for managing assembly versions.

• Visual Basic Drawing images to a picture box?

  I'm trying to draw multiple images to one picture box (for a map editor) so that I can save the picture created as a file. I've been looking around but I can't find any help on it, so I'm posting here. It uses ONE picture box for the map and you can load one tile at a time, so I can load from the filename, from a hidden picture box, whatever I need to do. Thanks for everyone's help. It's fairly simple to do... If you're going to be making 2Danimation, you may want to consider directx.  i have made 2d engines with the graphics object, and it looks 'twitchy'...  There was nothing wrong with the code, just didn't refresh correct ...Show All

• Windows Forms Possible bug in transparent forms

  I am working on an app with a transparent window. I do the standard things such as create a background image, set the transparent key to match the background, set no border, etc. If I set the BackgroundImageLayout to be "Center", I no longer get a transparent window. If I leave the image as "Tile" then I do get a transparent window as expected (i.e. the window is non rectangular and looks just like my image file.) I don't know why it should not work if the background image is "center". So far, the best I can do is set the image to "tile" and then size the window, but this does not work if I want to be ...Show All
