C# - Drag And Drop From Excel Cells To A Drag-enabled Task Pane Programatically?
Oct 31, 2010I am using Excel 2007, VS2008 Pro.I am building a VSTO Add-in that requires "drag and drop from Excel cells to a drag-enabled task pane".So far I notice that I can only drag and drop within the cells themselves. It does not allow me to drop into the task Pane or drag past the sheet limits.(http:)[url]...
Note: The task pane has drag drop enabled, I ahve already tested I can drag/drop from task pane to excel but I need to do this the other way around?
Hypothetical Controls - Options Checked As Enabled In FrmConfig Effects - Controls (like Buttons/menu Options) Are Enabled In FrmMain
Nov 26, 2010As i'm learning more and more about developing ive just got my head around creating classes and modules, i started wondering about something to do with configuration of applications where deployment is in a more diverse environment say in a company where different branches dont need access to all parts of a program, so i thought id throw the question out there in a basic sense and get some feedback. so i can go off and do some more reading and learning.
So the scenario in my head is like this.
So we have for arguments sake FrmConfig which is the master configuration form, then we have FrmMain which is the root menu our application general user interfaces with. So here based on what options are checked as enabled in FrmConfig effects what controls (like buttons/menu options) are enabled in FrmMain.
Copying From DataGridView With Gridlines
Apr 11, 2011I am trying to copy from a DataGridView and paste into a new Outlook email.

Right now, I'm pasting the data from the DataGridView using the dgv.GetText property. It is pasting the copied text, but is not lined up at all.

View 2 RepliesChange The Color Of The Listview Gridlines?
Jun 6, 2008Is there a way to change the color of the listview gridlines (black would be nice)? I have Gridlines = True, but the color is so faint that they cannot be seen (for example on Win XP with the default Blue theme). You can only see them on a highlighted item. (If I change the backcolor of the LV to a funky color, I can see them, but I want to keep the default color of "Window" (white when Win XP default them is used).

Feb 24, 2010I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.

Display Excel File (even If Excel Is Not Installed) Library? Method?
Mar 5, 2012I have a project that has a need to display a Excel file in second window, but because other controls are needed, simply launching excel is not sufficient.

View 1 RepliesOpen Excel File And Reusing Existing Excel Instance?
Jul 13, 2010I 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.
