I am looking for a third part control/DLL to run a series of virtual camera's so I can analysis a series of pre-recorded video streams simultaneously. I have downloaded several virtual web cam products, some of which work well for single camera simulation and have send E-mail inquiries on purchasing a control but have only gotten back bounced e-mail messages or nothing at all. Can anyone point me to a control for sale or even better, free?

I am looking for a control/DLL to add to my c# solution.

Got it, this.PanelName.DrawToBitmap. Thanks!

Is there a way to display the current contents of a panel on a second panel? My hope is to have an image displaying on a small size panel and when clicked, it will also be displayed on a much larger panel.

You pointed in a good direction but I still don't know why this is happening. I checked the row added event on the grid and sure enough, when that is getting fired, there is an additional null row in my DataTable which is affecting the grid. When the new row in the DataTable gets committed, the null row disappears from the DataTable but the grid hangs on to it. I can't find any problems with the logic that adds the row to the DataTable so I decided to loop backwards through the grid and get rid of all rows in the DataGrid that do not exist in the DataTable.

I have a DataGridView that has a DataTable set as the data source. When I add a row to the DataTable, it does get added to the grid but it is followed by a null row that sits between the row I just added and the next new row. How do I prevent this bogus row from appearing on the data grid?

Excelent! I knew there had to be a way to do this but was not readily finding it. Works perfect! :-D

I have a context menu I use for multiple DataGridView objects. When I click a menu option, the sender info seems to be the label of the context menu item, not the grid associated with the actual click event. How can I retrieve the name of the grid associate with the context menu click?

I moved the calls to my re-draw to the paint event for the user control and all is well. Looks like you gave me what I needed. Thanks.

I have a user control with a panel on it which I paint rectangles and text on using the following method - Graphics mg = this.CallsPanel.CreateGraphics(); When I minimize or switch back and forth between other application windows, I loose the graphics. I have been trying to figure out which event to wire a re-paint function to but am not having much luck. Or, is there a way to anchor the graphics that have been painted until I invalidate and update the panel?

I have a main form that is set to auto scroll so that when lower screen resoloutions are used, scroll bars are provided. The controls are not getting set back to position 0,0 but are displaying where ever the last scroll bar displayed the previouse control. Any way to get the controls to reset to display back at 0,0 and the bottom scroll bar to reset back to the left and the right one back to the top?

Thank you very much. This syntax works perfectly.

I am trying to set the height and width of my main form programaticaly. What is the syntax for doing this?

Sean, you got me pointed in the right direction. I worked with one of the more experienced Windows developers here and we managed to cobble together the following which seems to be working. Evidently it needed a reference to the table adaptor and needed a select command added to the data adaptor. Here is the code - SqlDataAdapter dAdapter = new SqlDataAdapter(); SqlCommandBuilder cmdBuild = new SqlCommandBuilder(dAdapter); dAdapter.SelectCommand = new SqlCommand("select * from Species"); dAdapter.SelectCommand.Connection = speciesTableAdapter.Connection; dAdapter.Update(markingDBDataSet3,"Species"); Thank you very much for your help!:)

I added the code as sugested - SqlDataAdapter dAdapter = new SqlDataAdapter(); SqlCommandBuilder cmdBuild = new SqlCommandBuilder(dAdapter); dAdapter.Update(markingDBDataSet3,"Species"); I am now getting a different error. Error - The DataAdapter.SelectCommand property needs to be initialized.

I am using a SqlDatatAdaptor and when I try this solution, it builds without any errors but when the update is executed, I get the following exception error - Update requires a valid UpdateCommand when passed DataRow collection with modified rows. This is my code - SqlDataAdapter dAdapter = new System.Data.SqlClient.SqlDataAdapter(); dAdapter.Update(markingDBDataSet3, "Species");

I have some grid controls on a form that are using data adaptors to fill the grid directly from the SQL Server data base. I have added an even handler on exit of the form to commit changes but the changes are not getting written back to the data base. Here is my code - this.speciesTableAdapter.Fill(this.markingDBDataSet3.Species); private void MasterData_FormClosing(object sender, FormClosingEventArgs e) { SpeciesGrid.CommitEdit(DataGridViewDataErrorContexts.Commit); SpeciesGrid.Update(); } I must be missing something or I am totally on the wrong track. Any ideas? -- modified at 18:42 Monday 22nd May, 2006

I am calling a form that prompts for some values and then displays a directory browser dialog box. When I exit back to my calling form to continue processing, a partial image of the dialog box remains on the screen until processing has completed. Is there a way to re-paint the calling form to clean up the display while processing proceeds?
