I have a databound datagridview. When I click the close form it goes into an endless loop. The dataerror event is repeatedly called and the context field states that there is a formatting error. Never had this problem in 2008 ?

I am using visual studio to create an application that opens an excel file and then for each entry in the first column the entry in the second column is stored in an array. Then excel opens two other workbooks and for each entry in the first column it searches for a match in these other two workbooks and stores the corresponding value in an array.
Anyway, the problem is closing excel afterwards. I have used the thread: [URL] to work through the basics of cleaning up. I used the cleanup code provided and added the WithEvents caveat. I do not have strict option on.
I believe the problem is the fact that I have three workbooks open.
This is my cleanup code: (wrkbk, wrkbk2, wrkbk3 are the workbooks; datasheet, datasheet2, datasheet 3 are the worksheets; excel is the application)
Code:
GC.Collect()
GC.WaitForPendingFinalizers()
GC.Collect()
[Code]....
I got the impression that order was important in the cleanup procedure so I have tried some variations of moving the workbooks and worksheets around.

Is it easier to print a VB.net windows form in Visual Studio 2010?
I have been struggling with this - the PrintForm utility in the Powerpack only prints the displayed portion of the current form.
I spent a lot of time creating a process which loops through each control on my form, converts to a bitmap, and drops it on the print document, only to finally discover that the RichTextBox control (which I used extensively) does not include a functional DrawToBitmap method.
I have already researched various ways of managing this, but if VS2010 will do it without jumping through the hoops then I'll spring for it like the sucker I am.
I can do this in Access and VB6, I believe, so I don't think this is an unreasonable expectation.
i just got visual studio pro 2 days ago and every time i create a project, close VS 2010 and when i come back to work on my project and i click on my Form.vb i got every time : Visual Studio has stopped working.Then i tried run as administrator it doesn't work.

View 2 RepliesI've inherited a large Visual Basic project that has a number of "frames" (obviously, it came from Visual Basic 6.0) which are now GroupBoxes. They all cover the entire form. The program chooses which one to display during execution. That all works fine.
Is there a way to switch between them for display in Visual Studio designer? Now it's displaying only the last one added, and I have to go to the code rather than Toolbox to make changes to all the ones behind the top one.
I have a vb.net application, and I want to know how to find the coordinates of the pointer (mouse) when it is clicked on the form. Not much else to say, so I'll leave it like that.
View 3 RepliesI've decided to learn Visual Basic .Net as this is what some of my colleagues work with, and this will allow me to work with them on projects.I have purchased Microsoft Visual Basic 2010 Step by Step and downloaded the sample files. When I am trying to debug the first sample application (a Windows form), it is telling me that it can't load System.Drawing V4.0.0.0. However, if I create a new Windows Form application (C# or VB.Net) this works fine.
I had a look at the References tab in the project settings and System.Windows.Forms is referenced, but the version referenced is 2.0.0.0. I have removed and re-added this reference and it stays at 2.0.0.0 and I still get the error.Does anybody have any ideas as to what may be going on?
How to create a Random quiz? I use groupboxes for every questions that i have because it has 10 items per quiz then i have 10 groupboxes.

View 5 RepliesThe title pretty much precisely asks the question, but I shall repeat;
When I double click on a form control while in the design view in a Web Application project within Visual Studio 2010, say a 'button' or a 'submit' for example, it inserts a javascript function into my .aspx file. When I do this at work it automatically creates an event handler for the control in the code-behind.How do I change this to that setting? I have used '/resetsettings' already, and other answers to similar questions do not solve my problem. I have reinstalled, gone through every menu I can find (though I may have missed something)I don't want to type those event handler subroutines every time!
Does anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.
At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates
Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?
I am just wondering how I can add Direct X references to Visual Basic in Visual Studio 2010 Beta 2. I cant find them in the .NET reference list, or the reference list, or anywhere. I downloaded the Direct X SDK for August 2009, but I can not add the .dll files to the reference list. Is there anything I can do to add them? I need the references for programming reasons.

View 2 RepliesAt present I have wrote an application (in-house CRM, vb .net 2010) which allows me to send emails under the selected customer & I categorised these emails.As these are categorised I can return data to display email history in my program by using search criteria:
Dim oMail As Outlook.MAPIFolder = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderSentMail)
Dim sSearch As String
sSearch = "[Categories] = '" + "[" + tAccount.Text.Trim + "]" + "(" + tShipTo.Text.Trim + ")'"
Dim oItems As Outlook.Items = oMail.Items.Restrict(sSearch)
However the limitation to the above is it only looks at sent items & no other folder.My ideal solution would be to display all email correspondence for a certain contact.

View 2 RepliesHow does Visual Studio and other similar programs display a form in their IDE? Is it possible to achieve the same or a similar effect using C# or VB.NET?
View 3 RepliesI'm working on a project started in VB9 (VS 2008) and now I've migrated to VS2010 (VB10) but on the production server the IDE is still VS 2008. On my developement enviroment the code compiles fine, but sometimes, - let's say - I forget an _ at the end of the line which causes the VB9 compiler to throw an error.So the question is, how could I build a project with the VS 2010 IDE but VB9 compiler? Or to force the VB10 compiler into VB9 mode?
View 2 RepliesI have a parent form that has a list of items and each item has a unique ID. The user can open one or many of the items in a child form (it is set up in a tabbed MDI), but it can only open one instance of each item at a time.
In the parent form, I was going to make a collection (or something like that, maybe there is a better way) to keep track of which items are open in the child forms. I need to know when each child is closed so that it can be removed from the collection and reopened at a later time. I was thinking that when the child form closes, it somehow does something (like raise an event) that tells the parent form to remove the unique ID from the list of current open child forms.
My questions are, is this a good way to do this and I am pretty sure I would use the form closed event in the child form to update that parent form, but as well, I didn't know if this is the best way of handling it.
If raising the event is a good way, are some examples on how to do it out there? I found some for controls, but not while the form is closing/closed.
I have to develop an application using MS Visual Studio 2005 or above with the following objective:
* The application should allow users to create as many new forms as they want and each form should behave like a MS Visual Studio WinForm. By saying that it should be a container for drag and drop of controls from the toolbox that I will develop....
* Once the user design's each screen to his taste by placing various controls on the form, he should be able to save the form as a screen. Of course I have to provide functionality for each of the controls such as if he drags a button on to the form, he should be able to specify what action it has to perfom when clicked when the application is put into run mode. Quite similar to regular windows form button.
* My application should have two modes: a DESIGN MODE, where user can drag, drop controls and specify what they should do when put into RUN MODE. This is quite similar to MS Visual Studio designer.
* Last but not least is to be able to access the application via the browser with the same look and feel his desktop version.

Now I'm at the end of the first part of my project and now i need to print a voucher with few pre-printing words and 7 fields that comes from a dataset.I try to use *rdlc file on which i made all the necesary layout very good, and the link was very good as well But print NO I did something in *.xaml file very dificult to put controls and make the links.But lets say i will do it, for the moment i have a picture and a label with few words, and I'm trying to print it with the following lines
Dim myPrintDialog As PrintPreviewDialog = New PrintPreviewDialog
Dim myDocument As New PrintDocument
myPrintDialog.Document = myDocument
myPrintDialog.Document.DocumentName = "OrderVoucher.xaml"
myPrintDialog.ShowDialog()
But in the dialog I see only a blank page.Of course I have a mistake in my mentality of building my code but I don't know where is that.I also need to admit that is the first time in my life which I'm trying to print from Visual Studio 2010.Now Please I need the best assistance you can give me.For the moment i want to print in my default Laser printer.But in the final stage i will have to print in an Olivetti PR2 (Bank printer) which will be connected in the com: port.That will be the day if I succeed :)
