View 5 RepliesI hv installed VS2010 Ultimate on my Samsung notebook win 7 home premium 64 bit. But one thing was wrong, i couldn't get sql express installed, with some error that i forgot. I can't see SQL Express menu on my menu list though unable to launch it.
after searching the net, it says that i might need Windows Installer 5 (SDK) which is 2,5 GB to download. Is it true that I need that SDK to install sql express properly? or it is not possible to have sql express on home premium 64bit?

Can you simply hard code something in VB Express?

I am trying to make a user account SQL database work with Visual Basic 2008 Express for login purposes, i.e. usernames & passwords. Plan is to host this server so people can login to use the the application and verify they have a valid account. I would like to host all the account information in SQL due to the possiblity of hundreds of users at any given time. I also need the ability to add data to the database for users registering for the first time. The SQL server will need to be able to access the SQL Server databases remote via WAN.

View 2 RepliesI added a new database using SQL Server Management studio express 2008. I can connect to that database using Web Developer and Visual Studio just fine. But when I try to connect from VB Express 2008 I get an error message "file in use by another program". VB only prompts me for the name of the database, but Web Developer and Visual Studio prompts me for both server instance and database name. I'm sure this is just something simple I'm missing.

why do the following code does work in VB2008 while it works very well in VB6 or am i missing something...?
Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
if KeyAscii = 13 then
lblTot.text=val(txtQty1.text) * val(lblRate)
txt.Qty2.SetFocus
End Sub
When running it shows KeyAscii not declared but the same works well in VB6 (the following code)
Private Sub Text1_KeyPress( KeyASCII As Integer)
if KeyAscii = 13 then
blTot.text=val(txtQty1.text) * val(lblRate)

I tried to start using VB 2010 Express with a program I originally developed with VB 2005 Express that I moved to VB 2008 Express successfully a couple years ago. It uses a database file (*.mdf) that is on the computer ( not out on a server). When attempt to run the program in debug mode, I get the following error "An attempt to attach an auto-named database for file C:Documents and SettingsTomMy DocumentsQuizzing StuffQuestion Database 2010QuizQuest ionGameQuizQuestionGameinReleaseQuizQuestionDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
I first made a copy of the entire project folder that was working in VB 2008 Express and gave it a different name. In VB2010 I opened the project in the copied folder and it said it successfully converted the project. I am able to open the Data Source inthe Designer and see the database structure as I expect. I think the project is still using SQL Server 2005 Express (because it is what is checked in the list of prerequisites on the Publish tab).
Note, I have programmed off and on for many years, but fairly new to using databases and SQL Server.

View 1 RepliesI am trying to re write a VB6 program using MS Access, many years ago, using VB 2010 express and SQL server 2008 R2 Express. I have a database with several tables, which I created using the designer. I am able to connect to the database and select data and display it in textboxes etc in vb code. What I have not been able to in code is to INSERT rows DELETE rows or UPDATE any data in the tables. I can do any of these operations using the Query Designer, but I want to do it in code. I can post some code if necessiary, but I thought it might just be some property that I had not set in the designer.

Is VB Express 2010 slower to compile and run that older versions of VB Express? I've installed it this weekend and it seems a little sluggish on my quad core computer with 1 gig of RAM. I have VB Express 2005 installed for my students at school and it seems to fly just fine. Those school computers are older P4s with 512k of RAM.

All of the instrctions I have tri9ed seem to be written for someone who already knows the answers. Here's my problem.I wrote a program using Access, with one table and five queries and it works fine. Using that program as a baseI created an SQL Server database within Visual basic. Naturally I changed my code to reflect SQL rather then OLEDB.When I try to run the program I get an error message telling me that the database is not registered. When I use the SQL Server Management Studio Expres, it shows my database by give a big message that the database is not registered.
View 3 RepliesInitially my app worked with excel fine, now it causes my computer to reboot only after Excel has been opened (two or more times). I have opened and closed Excel files 20+ times without running thru either of my apps (they all uses identical code for excel) and it has never caused a reboot or a crash.
run either of my apps and have the app control excel has become a crap shoot, it will reboot my computer. Adding to that I then have to do a manual shutdown because the reboot process after is unstable. (System doesn't respond properly). My code in this app is small, should make for a good example. I can provide the entire project to anyone who would volunteer to test it. (First I need to know how to send the project).

I'm trying to add a control on my form and each time an error pops up : "Failed to import the ActiveX control. Please ensure it is properly registered". I'm currently upgrading from VB6 to VB.NET (VB2010 running on Win 7).I installed vb6 on my win 7 PC and i can still add that control on any form - so definitely the OCX is properly registered. My guess here is that VB.NET is unable to create a COM wrapper for that OCX.

What is the Best way to create scheduler ?
I can think two ways,
1) to create endless loop that keep checking for time of day, so if i have an event (stored in my DB) that should be execute @ 14:30 the loop will compare in every loop the current time against the DB time so when the current time will be 14:30 the event will be executed
2) the same as above just using Timer instead of endless loop.
the problem is that both methods seems to be inefficient because at least 95% of the checks will be for no use.
so is there any methods or some way in VB.NET to raise an event in a specific hour without keep checking the current hour every second ?
