View 2 RepliesI am making a windows form and through this form i want my users to upload and download files stored in a Directory on a machine running windows 2003.Could anyone please tell me the best and secure way to share files on a directory for users to Upload and download and "without letting the users to know the actual path"..User Clicks on a Button and it will automatically download the files from server.User Clicks on another Button and it will automatically upload the files to server.The file name and paths will be taken from labels which are hidden on my form so the user doesn't need to specify anything..I have 3 Options and looking forward to some expert opinion on this.

I been google search for a while (a month at least). My problem before is how to read raw data from access. however, i find out that access not suitable for my project. I more interested in using Excel, because for later analysis i would came out with graph using excel rather than using access. Since, i been develop a GUI Program for Battery Cyclic Test. The part for Cyclic Test and DAQ Interfacing is done already.
My weakness is not been able to understand/know how to read raw data for particular column, and display it into textbox. In many out there forums or discussion, they explain about this kind of database by using class in VB. But, i would like to implement excel data manipulation in VB-Window Form Application.[code]...

View 2 RepliesVisual Basic 2010 Express: I have a form with a combobox that is populated with the names of locations from a datagrid which in turn was imported at run-time (Form_Load) from an Excel database. The Excel database (and the datagrid) also stores the information for addresses and phone numbers for their respective locations.
What I would like to do is have the phone number and address text boxes automatically be updated with the proper corresponding data when the user selects a location from the combobox. Whether the text boxes are updated from the datagrid or Excel database is not a concern; I'm mainly looking for whichever way is simpler.

View 6 RepliesThe idea is that I have certain values stored in textboxes/listboxes and thus can I store the information in a spread sheet. And if I change the value in the spreadsheet can it also change the value in the application? I had one idea which was to make both store data in a txt file and read from that, but I'm not quite sure how to do that either.
View 1 RepliesI need to access the current instance of MS Excel. To do that, I wrote the following code:
Imports Excel = Microsoft.Office.Interop.Excel
Imports System.Diagnostics
Private _ExcelApp As Excel.Application

The code runs nice, but it has a problem: After the user close the Excel application (click button X - note: no other instance of Excel exists), if you open the Windows's task manager, its possible to see the process Excel.exe.
If I open and close the Excel application, there is no process Excel.exe, but if I run my code with the Excel application openned, after the user close the Excel application, the process Excel.exe isn't finished.

View 2 RepliesI want to encapsulate the use of Excel Interop to make it easier to use somehow in a reuseable library.So far, I have written some tests that work good altogether, except that between each test, I force Excel to quite so that it does have handle on the test file no more in order to be able to delete.Once I quit the application instance between after each of my tests, Excel seems to be no longer responding, causing Windows to display "Excel has stopped working and is looking for a solution"
message. This message lasts a few seconds, meanwhile Excel is closing, causing the hang on the file to occur and my tests to throw an exception like "Cannot access file because it is being used by another process..."
