Using Which Exports A Datagrid View To An Excel File
Apr 17, 2009
I have some code that i am using which exports a datagrid view to an excel file. It works, I am trying to either delete or clear a series of unused columns at the ens of the sheet, there are 9 columns. I am using the following loop to rid the columns and i am getting Exception from HRESULT: 0x800A01A8.
I did some research and it seems to do with late binding, code that is giving me the exception follows:
Dim ZZ As String = "J"Dim AJ As Excel.Range = CType(wSheet.Columns("A" & ZZ), Range)
With AJ
For g = 1 To 9
.Select()
.ClearContents()
[Code]...
I read on msdn if AJ in this case starts out as nothing then vb will throw this exception and to use early binding. I cant bind a column if it hasn't been created yet, so i played around with the placement of the declaration of AJ to no avail, what is the right Direction i should take to fix this issue?

I have an application which opens one of several excel templates, fills a datagrid view with Excel Named Range data. Once the data is modified in the application I neet to save it to an excel spreadsheet. I currently have the following working:1. This sub writes 2 columns of data (Ingredient) and (Result) from those named ranges and places them in the datagrid
Private Sub CboBoxTypeCofA_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CboBoxTypeCofA.SelectedIndexChangedWorkbookTemplate = ""CofABook = ""
[Code]....
This code works and the only problem is that after running the code the excel application does not close.Now I need to write the completed updates from the datagrid view and the other controls back into a workbook.Ive been searching around but have not found the proper way to do this and how to kill the oexcel application in the code above.

I would like to learn, to view the excel file from our vb.net. When I try to display the Excel file through the process, suppose if there is no process for excell.exe, [means not opened any excel file or excel.exe is not running in task manager] then that file can be viewable smoothly from following code.
But supoose previously any excel file is opened means, then its giving error like "Object reference Not set to an instance, use New Key word....." Also when i try to kill the process for excel.exe, it will kill the other opened excel files also.

I am writing a program that uses several textboxes that a user will fill in and then click the add button to add the data into the datagrid. There is no backend database or anything. Just seeing the data in the program only.
What I want to do is then export this data from the datagrid into a file, preferably excel.
I've done copying textbox data into txt files but I can't find a method to copy datagrid data into a file.

What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?

I am trying to see if the controller class name is the name of the controller name passed in. I think my lambda expression is wrong and that is why it isn't working properly. I am passing in the correct controller names, but the export variable is always null.

controllerName As String)

I'm in the process of adapting a current program that I've created to automate it. **Current State***User selects an excel file and the contents are loaded into a DataGrid User can select which environment to run their query against (stage/prod) Program completes processing and updates datagrid with new values User can export datagrid to excel What I'd like to do is centralize the program on one computer and have it monitor a network folder for creation of a specific file type (*.xls or *.xlsx). If one of these is created in that folder then I want to add that file to a queue for processing. Once done processing I want to send the results as an attachment to an email to the user that created the file. After a file is processed I would like to remove it from that folder as well (into a diff folder of completed items).

I have a tbl called tblProjectpatients which also has 2 fields Yes and No (these have the data type - Bit).
These two fields have been populated with false and true values.
On my form, I have a datagridview which is populated with various values from tblProjectpatients.
The problem am facing is that the checkbox's for Yes and No on the datagridview are empty at runtime eventhough at the backend they have either False or True values.
I am expecting the checkbox showing on the datagridview to be either checked or Not Checked depending on the True or false values.

i'm having with a problem to refresh my datagrid view. I have 2forms and a database create from msaccess2010. This programme is too simple, in form1 requesting a costumer name and save button. After being saved, it'll show form2 which is database in datagrid view. Yes, in first save the name of costumer are being shown there but after i close (which is 'hide' actually,i cant use 'close' due to particular reason) and reinsert the data in form 1 and save it,the second data are not being shown in form2. So my question is,how can i make the data refresh(by form load or button refresh,any of them)?
