I`m trying to write a programme ,in VB2008 Express, to receive Serial Port Ascii data ( from a Multimeter) and display it as Hex Data in a textbox. I can get the Ascii data to show, but just cannot convert it into Hex. Once I can do this I want to write a new front end for the Mulimeter software.

View 4 RepliesA simple database has been created in Access, which is just basically a table of text, with some images as entries. A form has been created in VB2008 Express and linked to the database. Either a combibox, text boxes or pictureboxes are linked to a column form the database. The first row entries are all displayed correctly in the relavant boxes (except for the images, which for some reason aren't displayed). If another value in the comibox is selected, the other box values don't change and there is still no images visible...
View 1 RepliesIs there any advantage to using the VB2010 express version versus the VB2008 express version? Can they be installed side by side or will VB2010 express replace VB2008? I have no issues with the 2008 version, so I don't know if installing the 2010 version would be of any advantage.
View 9 RepliesOkay so I have decided to upgrade my game from vb5 to vb2008 express edition. When I opened it I was told it needed to be converted so I said ok. However, there are some things in the language syntax that have changed.Obviously. Well here is one of them:

Setting controls to objects allowed me to cut down on typing but it seems you are not allowed to reference things without the "full path". I understand that you now have to set the full path of the object but doesn't setting something to an object already do that? Do I have to just delete the object references on the top and instead of using objCmbGraveU2 I now need to replace it with frmMain.cmbGraveU2?

View 1 RepliesI have a VB2002 program that works. When I run it in VB2008, it updates, and runs and debugs until I shut down. When I try to start it up again from the updated SLN, or try to run the .exe in the BIN folder, I get the message "This application has failed to start because the application configuration is incorrect.
I checked the error logs and it says there is a syntax error in the first line of the vhost.manifest file in the BIN folder. The first line is the xml declaration and it includes the parameter standalone = "yes".
When I put the error message into Google I only get references to Visual C++ compiled programs running on machines without the C++ redistributable dll. That doesn't seem to apply here at all, since I have the VB 2008 express edition installed on this
