    replied to DrawToBitmap doesn't work on panel
    in C Sharp
    Sorry, I forgot about this post when no one responded and went to another forum.

    It turns out a control can only be printed after it has been added window and drawn. In order to get this code to work as intended I had to show the item off screen before drawing to a bitmap. But in case the item was already being show on a dialog I had to include code to re-add it to it's original parent.

    Code:
    void printDocument_PrintPage(object
    ...

      DrawToBitmap doesn't work on panel

      So I've written a class that has a stores some test results info and then a control that displays that info to the user. I want to put a print function on this class to draw the control at a full page size and print it. However it always comes out blank. The code see the panel as a control because it could be some other type of value. I figure there must be something simple I'm missing.
      Code:
      void printDocument_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs
      ...

        in C Sharp
        The only way I know of to do drag and drop from within your application is to manage it yourself using the MouseDown and MouseUp events.

        In the MouseDown event on the ListView store the image that is being dragged. Then you check to see if there is an image being dragged in the MouseUp event and handle it. You'll have to implement the MouseUp event on all controls to clear out the current image being dragged if the user drags the image...

          I believe the answer is not in how you're writing the data but in how you're reading it. If I write the string you provided to a text file with Unicode encoding and then open it as a ASCII encoded file I get this:
          Code:
          ÿþHeader%008,00821003173,00821003173,862,1/14/2012,1/14/2012,BKRM,00821003173,1/15/2012 2: ·30
          Which looks like it might be your data.

            replied to How to set selected value of combobox to datagridview cell
            in C Sharp
            I believe you can use the SelectionStart and SelectionLength in combination with the Text to get the selected value:
            Code:
            dataGridView1[row, column] = comboBox1.Text.Substring(comboBox1.SelectionStart, comboBox1.SelectionLength);

              in C Sharp
              Are you saying this works on one machine and not another? What are the difference between them, are they both running the same version of Windows and the .NET framework?

              Also why not use StreamWriter's constructor that accepts encoding as a property. Then you can avoid having to encode the string yourself:
              Code:
              StreamWriter fs = new StreamWriter(pPath + @"\" + pConfirmationNumber + "-" + pHHID + "-"
              ...

                  I'm mildly confused as you what specifically you're asking but either way I think the answer is no.

                  Running threads are separate entities from form will not be interrupted by the minimizing the application window. Threads can even be run in the background without any window open.

                    in C Sharp
                    Maybe someone can correct me but I do not know of anyway to communicate with a process launched with the Process class. You could however use the WebBrowser class to load the page within your program and use the DocumentComplet ed event to do what you need to after the page is loaded.

                          The condition you are checking is the same as the one for the if statement giving it the opposite logic you want. (Or is that an issue with the clean up?).

                          And for the stop function it could be the use of the Abort function. This causes the thread to be completely stopped no matter what it's state even if it's mid communication with the hardware resulting in all kinds of problems. The solution is to set a boolean flag when you want to...

                            Your problem is that the method you wrote works on a the DataTable object, which to which the filter is applied inside the BindingSource class. To iterate through filtered data directly use the DataGridView instance instead:

                            Code:
                            private void sumRows(DataGridView table)
{
    int sumRow = table.Rows.Add();

    Decimal num, sum;
    for (int i = 1; i < table.Columns.Count; i++)
    {
                            ...

                              in C Sharp
                              The XmlDocument class does allow for nested nodes. Notice in this example the newTitle XmlElement is added to another XmlElement, newBook. You can do this with your folders. When working with a sub-directory instead of adding the file information to the XmlDocument.Dou cmentElement XmlElement add it to one that represents the folder, then add that one to the root XmlElement.

                                The Stop function of the Timer class does not follow the typical "first letter of methods is lowercase" practice. That being said, setting timer.Enabled to false should stop it anyway. Is still running or are you just getting a single fire after the fact? Or maybe due to the way you programmed the dialog you're accessing the wrong timer?

                                    You have you debugged and verified the status of rawData? The code as you posted it throws away the data[] variable every time split is called, just as if you set an int from 3 to 5, the 3 is thrown out.

                                    In order to get what you described the next instance of rawData must have the data from the previous in it:
                                    Code:
                                    rawData[0] = "a1,a2,a3"
rawData[1] = "a1,a2,a3,b1,b2,b3"
rawData[2] = "a1,a2,a3,b
                                    ...
