I have created a picturebox in a form that I want to click on and then it would send me to a excel file that I already have created. I don't know if it is even possible. Do I need to use a button instead?, or am I just way off all together.

I have a bunch of Excel files full of research data. Everything is strait forward: rows of research categories and columns of research parameters. I want to create a simple search form that allows opening any of the spread sheets that contains the type of data that I specify. For example, I would choose a parameter

I've been in VB express for about tree weeks, formerly of VB 5 for about 10 years.
I need to open a form on top of the form of another application, that is, making the other applications form its parent. The title on the applications form can change, so searching for the form by name won't work.
I'm also curious, can you start a vb express application without opening its form? Like in Vb5/6 you could start in Sub_Main?

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.

Creating a new database in a Windows Forms project (done according to one of the MSDN tutorials) results immediately in a "The event log is full" error.The database exists as an item in the project, but cannot be opened or configured (i.e.,it doesn't exist really). newly installed MS SQL Server Compact Edition,This is a new computer (though fully updated), and to my knowledge no other versions of SQL server are installed.I note that someone else has contributed a message about the exact same problem (according to a preview in the MSDN search results page), although for unknown reasons clicking on the item does not take me to that message.

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.

I 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.

Initially 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).

Currently I am opening a file via this
Dim myStreamReader As System.IO.StreamReader
Dim SourceString As String
myStreamReader = System.IO.File.OpenText(txtInputFilename.Text)
SourceString = myStreamReader.ReadToEnd()
Sometimes the file I am opening is quite large and I am wanting to have a progress bar displaying the progress as I am opening/writing to a file.

If I create a DLL using VB 2010 express can it be used by previous versions of of .Net (3.5, 2.0)? Will the DLL use .Net 4.0 components, which is what I want. I don't see a way to force that to be the case.

this is my very first posting and I must say I am desperate. I have a VB assignment due in 2 days and I am so lost. I have written a code to draw some graphic, just a basic house, tree, sun etc. I have also written a code to magnify said graphics which were all the specifications of my Assignment 1 part A. Now for Part B I am being asked to extend my program so that: A - My graphic can be drawn using different colour schemes designed by me but chosen by the user B - My graphic or an appropriate part of it can be animated around the picture box if the user chooses to do so. C - Error checking is included.

Here are my questions concerning VB 2010 Express:
1. I've registered my VB 2010 Express, will it still expire?
2. Will the applications I made using VB 2010 Express expire after some time?
3. Is it OK to write my code in the designer.vb file? I don't know why, but when I started writing my application it took me to the designer.vb instead of form1.vb code.
4. I've been working on an application for a week now, but suddenly I can no longer access my Design View(Shift-F7). All my codes are written on the [form name].Designer.vb. I can still view my codes but I cant access my form layout. On the solution explorer, my forms no longer have the 'form icon'. When i press Shift-F7 nothing happens. Right-clicking the form on the solution explorer doesn't show 'View Designer' option. How can I fix this?

Is there a way to delay the start of a text file? I am using this to call the TXT file after clicking a button: (opens txt file)
Process.Start("text.txt")I was wondering if there was a command to delay the TXT file from opening for a number of seconds?I use this to delay the Splash Screen: (delayed 5 seconds)
Threading.Thread.Sleep(5000)Is there something similar for TXT files??
