Not sure if I'm posting this in the right area, but here goes anyway. I've been working with sql databases for practice, but can't seem to get around one thing; after I add it as a data source, I can't go back and add tables.
I start off by going through the project, then add item, choose the service-based database, and go from there. I add the tables, then go in and add it as a data source.
After I've added it as a data source, I can go back into the .mdf form and add lines and edit properties, but it wont update in the data sources. So, I can't add it to the form.
I have a very simple class that crashes the VB.NET IDE when I added this list. Granted this is a list with 10,000 items but it crashes when I added it to the project. When I delete it with a text editor outside the project does not crash. I have not installed SP1 based on the comments not sure if this is a know problem or not. I can post the project its fairly small as its just text.

In the project I'm working on I've been using some gif images to define one or more texture brushes. I have the images in a folder and I know how to define the texture brushes as follows.
[Code]...
Let's say I add the images as image files to my application using "Add Existing Item". Is there a way I can define the texture brushes with the images that have been added to the solution in that way and if so could you show me the exact code.
Is there any specific way of calling the form of another application.My main project is a WPF application.From that it is calling another application is Vb.NET.. This is done by creating a process and then calling the exe.
Dim fp1 As New Process()
fp1.StartInfo = New ProcessStartInfo("Location of the exe")
fp1.Start()
Now the problem which I am facing is that from that exe I need to call a specific form in the WPF application.
Are there any functions that can be called across the project.I mean we cn use Private Sub ABC() function in the document where it has been declared but is there any way that this could be called from any other form?

View 7 RepliesI have a vb6 project in which I use a dll library to do some tasks. For that, I add a module which declares all functions of that library such as:Declare Function myFunction Lib "abcdapi.dll" (ByVal hVar1 As Long, ByVal hVar2 As Long) As Long When I call this function (and many other similar) I'm able to do the work and correct Long pointer is returned. But when I try to do the same thing by VB.net (by importing the same library using dllimport and calling the same function), I get no result. although it does return some pointer but that doesn't produce correct result.

I've created a database in Access 2007 and connected it to Visual Basic 2008. My database have tables Coachee and Coach. Details of Coachee are displayed in one form and there's a button that when clicked will show details of the Coach of that particular Coachee in a another form. If the Coach is not in database, user will be prompt to insert a new Coach record. Problem is, when saved, the newly inserted record will not be displayed and i have to exit and rerun the program, only then the record will be displayed.

I have a question regarding VB.Net and Object-oriented programming.
I have a solution consisting of two projects.
One project is dedicated to the logic of the application, and one is only to show the Winforms form, and to reflect changes made in the logics project. In other words, when an array filled with various attributes residing in the logics project gets changed, then these changes should be reflected on the form (not that strange in theory).
Here comes the - for me - really tricky part:
I have created user controls, and these are residing in the forms project and placed on the aplication's form. When I click on any one of them, their respective onclick sub gets called okey, but how can I send a message to the logics project from their onclick subs? Basically, I'm not sure on what should be private or not, or possibly how to call the other project correctly. In any case, I can't get it to work.
To sum up: What I need is a line of code calling a class in another project, and someone telling me what should be private, static etc.

View 7 RepliesI have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500. To see what I am talking about, create an empty "Windows Forms Application" project and insert the below code into it.

View 11 RepliesIs it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).
View 1 RepliesI have a datatable property called prpParametersTable in a class called clsBatch. I have a procedure that sets a datatable variable called dtP equal to prpParametersTable at the beginning of the procedure. I then add three new columns to dtP.Here is my problem. When I add the three new columns to dtP my original table prpParametersTable also gets those columns added to it, why? I only want to add the three columns to dtP and not prpParametersTable. How can I do that?

View 5 RepliesFor reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.

View 5 RepliesI made a change to a project and hve induced a major problem. I have warnings and errors now, but I can still debug the project with the "last successful build" Iwould like to just revert everything to that build but I can't find a way to eliminate the problems I induced or find a way to go to a earlier build. Hopefully I can get back to an earlier version or I will loose the entire project as I can no longer get to the designer.
View 5 RepliesIf I put this piece of code in a new fresh vb.net form, add a button and two labels and start debug I get execution time of about 11.5s.If I put the same piece of code in a new form in an old project upgraded from an earlier version of vb.net, start debug I get an execution time of 7.5s.So I do exactly the same in the two projects but get different execution times.
What do I have to do with the fresh new project to get the same execution time ?I am not interested in improving the code to be able to calculate primes faster. I just want to know what is the significant difference between an old upgraded project and a new fresh one. I am using windows 7 64bit on a 2,4 Ghz Intel quadcore.
