exit VB2008 without saving the current project?Or to revert to the previous saved version?After trying a few changes in my program I decided that is was not the way to go. So I wanted to discard my changes and start again with the program the way it was.

In my form there is a DataGridView, the user select information in the DataGridView then there are text boxes that needs to be filed in. So this is what needs to happens if the focus is on the DataGridView when the user hits the Tab key it moves the focus to first text box. Then once the user hits the last tab box it returns focus back to the DataGridView but to next cell. Initially figured this would not be a problem and did this code;
Dim PreviousCell As DataGridViewCell
Private Sub DataGridView1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown

I have been getting sometimes with SOME libraries (be it included in the framework or not).[code]I'd expect the func.Call() to return an exception if something is up, or do anything to error out, but here it just murders my method which returns instantly! The same stuff here is also in a loop, which doesn't get any more iterations, it just stops executing this function and continues running the program.
View 1 RepliesI'm a newbee with VBnet , I use vbnet2005 I have a major form called FORM1, and when I click the bottons in it it shows another form for example-I have these some forms (printscreen):
FORM1 - major form
FORM2 - calculation form ( there are few forms like this)
FORM3 - result form
What I need is:When I open FORM2 and get results I push the botton SEND and then it should send the values into FORM3 I don't know if the public variable will be good here because they are not constant , I can get different results in FORM2 ,and these results should be writen in textboxes only after I push send bottom.
I hope it is clear , I don't know how to do it,if you can give me a code for this or detailed answer , I would be very glad.
I do not have any code to show, but using asp.net, vb.net, and SQL with stored procedures.If on a page I have an item that is added to the database and therefore that information is "saved", is there a way to have an ("exit without saving") button on the page that does away with those changes?Using infragisitcs ultrawebgrid, you add an item to one table. You can add an item to another table on that page. i assume adding these items to the table automatically saves in the database. There is also a text box but without clicking save I do not believe that those items are actually added to the database. Update panel is used, I don't know if that matters.
If after someone adds to the table but then decides.. oh wait.. I don't want to do this just yet, is there a "one-click" way to act as if I never visited that page to add info? I'm assuming it would be deleting the entries but this would have to be limited to deleting ONLY those items added while making... we don't want people adding info, then going back and deleting once the "save" button has been pushed.
I am using Visual Studio 2010..I have multiple forms and when I hit close button(red X, top-right) from any form, i want the project to close entirely.Now when I do this, this does not happen by default. I always have to click on the 'stop' button in VS for it to close.

Run project error from VB2008?
View 3 RepliesI am using Visual Basic Pro 2008 SP1. I am currently working on a windows application form project and everything was fine until recently when I try to add a new item (does not matter a new form or control), the whole program is frozen up. If I look at the task manager, the "devenv.exe" process memory usage keeps increasing until FatalErrorOutOfMemmory. I can run build, debug without any error. I can publish the project and run the program without any problem too. I have tried to open a new project and I can add a new form or control without any problem. I wonder if there is something in the project causing this problem and where I should start to troubleshoot it.

I'm trying to use a TreeView in my current project and I'm not quite sure if it will work.I need my tree view to load the TreeView with the contents of the C: drive. Along with this, I need the nodes to be "checkable" so that I can tell my program to do certain things with items checked. Can this be done? If not with TreeView, is there somethings that is free that is an add-in that I can use?

I'm having a bit of a problem getting my application to close properly. Basically I have one main form from which all other forms open. If a user tries to close that main form, I want to bring up a MessageBox asking if they want to exit the application.However, when I try to do that it asks the question twice. It seems that the Application.Exit() is triggering the FormClosing event again for some reason, but I don't know of another way to exit the application. BTW, the main form isn't the startup form so I can't use the option to close when the startup form closes.

Now I have a sub to validate a bunch of textboxes and combo boxes.I previously used many IF statements to validate and pop up different messageboxes and Exit Sub in every IF statement.But I heard that too many Exits will decrease the efficiency and they were not recommended to use. Instead, nested IF is better because it will let the process naturally go to the end.Then I found out that if I use nested IF,it will be hard to read, since messageboxes are all separated from conditions.

View 5 RepliesIs there a way to prevent the VB .NET editor from saving the project whenever IT LIKES TO ? It very annoying ; it so stupid that it saves things that I don't want to and that I didn't ask it to do .If I add a form and then close the editor , when I open the project again , that form is still there though I DIDN'T save it !If I change a declaration from Friend to Public and close the editor without saving , then when I open again the project , my modified code remains modified , though I DID NOT save it !Today I realized that if I delete some controls of a form and then close the Editor , then when I reopen it , the controls are missing for good ! It saved that modification by itself !
View 3 Repliesthe question im asking is how do i save my project WITHIN my project. For example, say i completed my program, made the forms, gave them their perspective design and gave names to all the objects and got the template how i want to look. Now the project im working on is being developed in visual studio 2008 (Visual Basic) Now the question im asking is how do i essentialy save a project that can be made with in the program i am building with the ToolStripMenuItem given the name as "Save Project As" In my program i am working on, what would be the code to save my project "as" with in my piece of software i am working on?

figuring out which multithreading approach to utilize in my current work project. Since I've never written a multithreaded app in my life, this is all confusing and very overwhelming.I've been assigned to take over work on a control application for a piece of test equipment in my companies R&D lab. The program has to be able to send and receive serial communications with three different devices semi-concurrently. The original program was written in VB 6 (no multithreading) and I did plan on just modding it to work with the newer products that need to be tested until it posed a safety hazard when the UI locked up due to excessive serial communications during a test. This resulted in part of the tester hardware blowing up, so I decided to try rewriting the app in VB.Net as I'm more comfortable with it to begin with and because I thought multithreading might help solve this problem.
My plan was to send commands to the other pieces of equipment from the main app thread and spin the receiving ends off into their own threads so that the main thread wouldn't lock up when timing is critical. However, I've yet to come to terms with my options. To add to my problems, I need to display the received communications in separate rich text boxes as they're received while the data from one particular device needs to be parsed by the main program, but only the text that results from the most current test (I need the text box to contain all received data though).
So far, I've investigated delegates, handling the threads myself, and just began looking into BackgroundWorkers. I tried to use delegates earlier today, but couldn't figure out a way to update the text boxes. Would I need to use a call back function to do this since I can't do it in the body of the delegate function itself? The problem I see with handling threads myself is figuring out how to pass data back and forth between the thread and the rest of the program. BackgroundWorkers, as I said, I just started investigating so I'm not sure what to think about them yet.

View 4 RepliesWhat I am trying tot achieve is the following:User inputs data in one form that saves to the dataset table no problems. On an edit screen I want the current data saved to appear in this page within all the relevant fields but when saving I want this data to add to the dataset table as an additional line of data so the transaction records are kept.I want to add a new datarow regardless of it saving one change or all 7 changes that are possble.
e.g. Line 1 - user inputs 7 cells of data Line 2 - user amends 2 cells of data Line 3 - user amends 1 cell of data an so on. Unfortunately the terminology for certain items above may not be correct as I am still new to this programming and still on a massive learning curve.At the moment I do not have the code for what I am trying to achieve as I really dont know where to start with it.I am currently able to save the data and have it appear in the "edit" panel however only the cells changed are saved an it overwirtes the initial input.
