View 5 RepliesI have a stand alone application "test.exe" on a Windows 7 operating system.I have an application "test.exe" made in Visual basic 8.0.I have an "Auto Update" function . Call this function from "test.exe". In the first line in "test.exe".This function does the following:
1. This checks whether the current version is older than the version on specific site, if so:
1a. Removed all *. old
1b. Rename test.exe to test.old
1c. dowload new test.exe
I'm afraid I get an error when I rename "test.exe" to "test.old" because "test.exe" is now active.How can I prevent this or what else should I do?
1. Just looking for some general help on how to auto update my application via a file location path (e.g. I have a HTML file containing the current file version and the .exe file to download)
What I need is to read in the HTML file version - DONE Check file version vs HTML file stream input - DONE Replace current .exe file with new .exe file - HAVING ISSUES WITH THIS
I know I have to close the application and then replace the old exe file with the new exe file then restart the application but looking for the best/safest way this can be done

I'm about to roll out a large application to many workstations throughout the company and I've never really had the need to "auto-update" an application until now. Ideally, I'd like a "one time install" and then updates are applied without user intervention/IS involvement. (user intervention would be ok as long as it wont require a logoff or admin escalation)

I have always made a setup file with "instal creator" which have made a nice one file of my program and it have been easy to share. This time I need a chance to update my application. I read somewhere that having website is necessary or its much easier to do that way, is it true? I have worked before with ucoz/unet so I think I could use it.

I'm creating part of a program which calculates vacation hours multiplied by accrual rate. As of right now all parts of the form are functioning and saving/retrieving data from a csv text file. My problem is that I'd like to bring the process out of a button.click event and into Form_Load. Currently when I click a listview item (lvwData.SelectedItems) it populates a textbox (txtAvail), then recalculates the textbox value based off my formula (hours) and updates the listview's 4th column item. To update each column daily, I currently have to click each row, then my button, then move onto the next item. I'm looking for a way to grab the 4th column, recalculate it and update the listview without having to select each row.

I may be deploying my app (its a database software for videos) to 4 - 5 computers. I want to add some new features but have the software update automatically and silently. Due to security holes or issues with bugs, I don't want to give the clients the choice to update. I just want it to check for an update and if one is available, it can SAY that its updating on a label but that's about it and it automatically updates without confusing the user or wasting any more time than it should.

View 1 RepliesCurrently I'm using a third party file hosting website (like mediafire) to upload my program and I update the link every time a new version is out.I know there are some ways to autoupdate the program but most of them need to own a website, which currently I don't have.So I was wondering if there could be a way to make an autoupdate using sites like mediafire.Example: I always delete old version of the program, on mediafire when someone try to access a deleted file page he gets redirected on a page which says "file deleted or invalid". So if the program find out that the file link redirect to that page it should inform the user about the new version.

Is there a way to auto-update a listview based on reading a column?
Requirements:
1) The code must make a call to a user-created "Private Sub" to recalculate
2) Update must be automatic. .SelectedItem or clicking a row will not work
3) The formula function cannot be included in Form_Load
I've got everything working if the user selects a row, then clicks an "update" button using .SelectedItem. But with my current program containing 200 rows, it's not feasible. Simply put, how would I go about updating a listview column (0 in this case) based off a call to a formula, then updating the row?
I have a windows form with a DataGridView control.I bound it into an attached DB file (.mdf).I perform insertion by generating a dynamic Insert statement. I then pump this sql statement into a SqlCommand object and perform ExecuteNonQuery() method. All of these is performed by handling a Button click event. The button and the gridview is located on the same form.

Dim strConn As String = (the connection string)
Dim sqlConn As New SqlConnection(strConn)

After the code execution, the DataGridView is not updating (remains intact). I have to exit the form and reload it to have the updated gridview.For certain reasons, I can't use DataTable object.But I would like to have this gridview updated everytime I run the insertion.

View 4 RepliesI have 2 workbooks( Book1 and Book2) with multiple sheets.I am only interested in one of the worksheets in the workbooks(both the worksheets names are the same).The thing is that the data is in the form of pivot tables, so each time i have to filter according to specific categories, copy and paste into another new workbook.The thing is column headings in both the worksheets are different,BUT BOTH the worksheets data must be combined into 1 single worksheet( row after row).
Meaning in Book1, my columns are in the form of Cost, revenue,margin and in book2, the columns are in the form of Cost,Revenue, Profit Margin %.... That means i must add a profit margin % column in Book1 and a Margin column in Book2 before I combine the data into a single worksheet. Each week, new data gets added into Book1 and Book2, so I wish to automate this by creating a code, so that when the source data changes, my new workbook's data also changes.
