Jan 28, 2010I'm trying to make a basic Windows Form and I'm trying to make it so once the first button is clicked, a set of new buttons come out which can also be clicked. I've gotten the first button to open up a set of buttons when clicked; but i can't manage to link events to the clicking of the new buttons.

That was my first guess, but I got some WithEvents error. I went back up to the top of the class and added Dim WithEvents BHorse As New Button. Now I don't get any errors but the click event isn't working at all.

Feb 12, 2010I am having a problem with using the SQL Server 2008 FileStream function with an Excel 2007 spreadsheet. I can store an Excel 2003 format spreadsheet and bring it back with no problem. When I bring the Excel 2007 format spreadsheet back from the DB I get a message that there are errors in opening the Spreadsheet and the Excel App asks if I want them repaired before it is displayed. I answer yes and the Spreadsheet is renedered perfectly. Could this be a FileStream problem or an Excel 2007 problem?

Apr 3, 2009I have this code which when I run the program and click on the btnReturn the form actually minimises to the taskbar. What I have noticed is that yellow and green lines have appeared next to the btnReset section and all the way to the end of the code and that the last line (private sub fmmxxxxload) had disappeared, which I replaced. Now when I run the program it still minimises rather than appears on screen. If I click on it in the taskbar, the correct form is displayed.

VS 2008 - Invoke The 'click' Event Of A Command Button
Feb 7, 2011It was pretty simple in VB6 to invoke the 'click' event of a command button (i.e.; btnNext_Click). I am having difficulty trying to do the same think in VS2008.
I am getting errors at line btnNext_Click(): Error1Argument not specified for parameter 'e' of 'Private Sub btnNext_Click(sender As Object, e As System.EventArgs)'.
Error2Argument not specified for parameter 'sender' of 'Private Sub btnNext_Click(sender As Object, e As System.EventArgs)'.
VS 2008 : Increment The Month In Datetimepicker Using A Command Button?
Mar 7, 2011Im trying to change or increment the month value of the datetimepicker using a command button. I tried to use the sample code from MSDN site but I was only able to increment once. I want to increment the value of the month everytime you click the command button. Do I need to use a loop statement? If so, how do I do that? I used this code below which can only increment or change the month value once but when you click the button again, no changes will be shown.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
'DateTimePicker2.Value = New DateTime(2001, 10, 20)
DateTimePicker2.Value = New DateTime(DateTimePicker2.Value.Year, DateTimePicker1.Value.Month + 1, DateTimePicker2.Value.Day)

.net - Excel Worksheet In Windows Form Application Without Opening Excel Application?
Nov 18, 2011I am converting several VBA projects to Windows form applications. The only problem I have is that some of the functionality of Excel is essential to the application, such as R1C1 formulas. I do not want to instantiate the Excel application or access saved worksheets. All of the data is retrieved by querying Oracle databases. 2-Dimensional arrays are not an option because the columns contain differing datatypes, and DataGridViews are too slow to work with.
I thought simply dimming a Microsoft.Office.Interop.Excel.Worksheet object would be enough, but the program kept failing and upon inspecting the object's elements in debug mode, I found that every value says this:
{"Unable to cast COM object of type 'Microsoft.Office.Interop.Excel.WorksheetClass' to interface type 'Microsoft.Office.Interop.Excel._Worksheet'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{000208D8-0000-0000-C000-000000000046}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."}
Recreate The Behaviour Of A Button Or Command Button On An User Control
Dec 20, 2011I would like to recreate the behaviour of a button or command button on an user control. I need to layout a group of this user control on a form so user can select only one at a time. When users click on one of this user controls a selection frame is drawn to indicate that it has been selected. The problem I have is clearing the selection frame when other control is clicked on. How do buttons or command buttons do this? If you layout a group of buttons only one is highlighted. I have tried using different events like LostFocus and Leave and nothing seems to work.

Opening An Excel File
Apr 22, 2010My company is currently using a Linux/Powerterm program that exports reports via email on a daily basis. I have a add-in program installed on outlook to automatically save the report to a folder on the server. The file that is exported appears to be an XLS 97-2003 Worksheet, but I confirmed from the original programmer that this file is not a true Excel file, I believe it is a unicode file, but it can be opened by Excel. I want to link these files to an Access database within my form, but Access does not recognize this file format.I attempted to create several programs in Studio to convert the file to an XLSX file, but on each attempt I receive an error the file is an in unrecognizable format which is killing me at the moment. I even made attempts to dump the data to an dgv but it still wont be accepted.
