I have an application the contains several excel files bundled with it. I'm not opening the files and processing them within my application. These files contain a data-connection to reload all of the pivot-tables within each excel file. I have a 'link' on my form, that when clicked, it determines which file to open and calls a sub using filename and executing Process.Start(filename) for any excel file I want to open. I have no problems opening any one of the files and then exiting excel.
The problem is when I 'close' a file, but don't exit Excel; then try to open another file(clicking link on form)... it creates a new instance of Excel.
I know from experimenting that the fileopendialog form will 'reuse' an existing Excel instance, IF it does not already have a file open.
How can I do the same thing without using the fileopendialog?
I don't want the end-user to have access to the folders where these files live. That's why I have multiple 'links' on my form, one for each xls that already exists. I just want them to be able to click on a link and the xls file opens AND if they choose to merely 'close' a file and not exit... Don't create a new instance of Excel, but re-use the existing one.
I took oledbconnection with excel file, after disposing this connection i m still unable to open that excel manually,It shows some access error.

So I want my program to open up an empty notepad window, and then fill it in and let the user save it as whatever they want. Is this possible in VB .NET, and if so, do you have any pointers? Note: I don't want to save to write to a file and then save it. I know how to do that. I want to write to a notepad window (an unsaved file). I hope this makes sense and I hope it's possible.

View 4 RepliesI need to open an excel file from vb.net and then search it for specific data. I then need to take those data and insert them into text boxes on a form that i have created. This is all controlled by a button click. I already have some code that will open a file dialog box and let me navigate to the correct file, but I am having trouble with the search portion. I have tried the Find function but I am not sure of the proper syntax. I am using Visual Studio 2008 and Excel 2003.

I am reading in data from an excel file that is only viewed inside the program. This excel file is being populated by data from multiple PLCs (7) through DDE links via RS Linx Gateway. I would like this data to be written to two different excel files and specific sheets within those so that it can be viewed later on.
My program has a form that will allow the user to view the data live, meaning they look at the first excel file from the program so that they are not able to edit the DDE links or change the file in any way. The other excel files (there will be two, one for good parts, one for bad parts) have specific sheets for each part and each tester station. For example, if the part is a ABC part, and it is a good part, and it was tester on tester station 1 then it needs to be saved to the good parts excel file, in the ABC sheet and in the good tester station 1 sheet.
If part XYZ comes along and is a bad part (fails testing) then it needs to be saved to the bad parts file, the XYZ sheet and the bad tester station 1 sheet.I might have added more detail than is needed to solve the problem but I thought I would add it anyways to help you all understand my problem a little better.
I am using Visual Basic 2010 Express and attempting to get information on how to Open, Close, Read and Write a disk file in Windows using VB. I have attempted to use help on the home page of Visual Basic 2010 Express with no results. It does not give me any instruction or sample.
View 3 RepliesLet's say, when you click a button it just opens a specified .txt file and adds the data of it to a listbox. I mean automatically, without that file opening dialog showing?
