View 7 RepliesI have a form that exports to an Excel worksheet (sheet1) and it works great, no issues there or anything. It's not a template, just a regular .xlsx spreadsheet, but I use it as my template. Now, the goal is for the end user to be able to fill out the form, and save it as todays date. How does it get todays date? In the Excel sheet, N2 is todays date, and it gets it from the form. Then save it in a specific folder.

I have a windows form application written using vb.net 2005 to generate and save an excel file. I faced some problems with the saving of excel file. The program will prompt a message box with 'Yes', 'No' or 'Cancel' options if the existing file exists. If user choose 'Yes', it will override the existing file. If user choose 'No', it will open a savefiledialog to allow user to specify the location and name to save the file. Do i use filestream object to save the file when user choose either 'Yes' or 'No'? How can i go about doing it or where can i find sample coding.

View 8 RepliesI am working on saving excel objects to a directory of my choosing. I am able to use a folder browser dialog to select the save location and the saveas method within the excel interop and i am able to create a file in the folder i select with the name i choose. The issue is that when i later go to open that file it is blank. no workbooks no worksheets etc . Just a seemingly blank file in the proper location with the proper name.
It should be noted that if i single click on the report icon to open it the microsoft browser window does show a tiny preview of what seems like the correct report.

View 39 RepliesI am trying to use the BGW to save a DGV to excel file, but don't know how to do it correctly, specifically setting the savefile name this code doesn't work gives me:
'System.Runtime.InteropServices.COMException' occurred
- Make sure the specified folder exists.
- Make sure the folder that contains the file is not read-only.
- Make sure the file name does not contain any of the following characters:
Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process. I also tried doing the Save in the BGW RunWorker Completed event but then there is no file name. It seems I need to pass the file name the user inputs in the SaveFileDialog to the BWG WorkerCompleted event somehow

I have a datagridview which has columns which are bounded and unbounded. My problem is when the user enters several rows in the dgv, only the data found in last row is saved in the access table. For example, if the user enters 2 rows of data, when he clicks the save button, there are 2 rows saved in the access table but both rows contain the data of the last row in the dgv. Below is the code of the save button.

I am new to working with DataGrids, Table Adapters, and Binding Sources so please bear with me.I have a form with a datagrid that loads when someone makes a selection in a combobox.

What I have is a program that is going to monitor and store different stats about different email servers. The basic layout of the main form is a datagridview. Now this program does not need to store the information into a database as it is only going to run on one machine which is why I did not bind the datagridview to a dataset. Maybe using a datagridview is not the way I need to go but researching around the only other option would be to save the data to XML. However since the table does contain hidden fields with authentication credentials, I am a little bit hesitant about doing so.

can anybody please help me with my problem. I have a database and I view the data using a datagridview, the problem is I cant update my database using the datagridview properly because there is an error in my codes. I just cant understand what I should do to make it run. I know there are lots of post about updating database using the datagridview but none of them is the one I am using. Please review my codes and tell what is wrong.

The error says that "the variable @a has already been declared..." As you can see I did not use the Me.Validate etc. to update my database because I do not know how to use them and I would like to focus on using this kind of codes in my program. This is the reason why the post about datagridview here are not useful for me.
I also included an example of what is being populated in the DataGridView from the xml file/schema from the start (see very bottom), which of course I'd like to be able to add more data to it via the DataGridView and then save it back to xml.
