Greetings.

I am working with DDBI and DFL. I am having a few problems where when I double_Click on a listview item I get "abnormal program termination". I start the program again and it works fine. I have placed a few msgBox, but when I do that, the program does not abort. So, I think that I must be doing something really fast where the listbox item is not ready for some reason. The listbox is huge, which may be the reason as to why, here is the list of it:
Code:
  private void initDesign()
  {
    ColumnHeader col;
    /* this is used to store the UniqueID row id */
    col = new ColumnHeader;
    //col.textAlign = dfl.base.HorizontalAlignment.CENTER;
    col.width =0; // invisible for id
    lview.columns.add(col);
    //msgBox("lview col index = " ~ std.string.toString(col.index()));
         
    col = new ColumnHeader;
    //col.textAlign = dfl.base.HorizontalAlignment.CENTER;
    col.text = " P-Id";
    col.width =40;
    lview.columns.add(col);
    //lview.columns.textAlign = dfl.base.HorizontalAlignment.LEFT;
    //msgBox("lview col index = " ~ std.string.toString(lview.columns.index()));
   
    col = new ColumnHeader;
    //col.textAlign = dfl.base.HorizontalAlignment.CENTER;
    col.text = "subPId";
    col.width =0; // invisible for ProjID
    lview.columns.add(col);

    col = new ColumnHeader;
    //col.textAlign = dfl.base.HorizontalAlignment.CENTER;
    col.text = "";
    col.width =0; // visible for parent which is really the project ID.
    lview.columns.add(col);
    //msgBox("lview col index = " ~ std.string.toString(col.index()));
         
    col = new ColumnHeader;
    col.width =0; // invisible for children
    lview.columns.add(col);
    //msgBox("lview col index = " ~ std.string.toString(col.index()));
         
    col = new ColumnHeader;
    col.width =0; // invisible for login
    lview.columns.add(col);
    //msgBox("lview col index = " ~ std.string.toString(col.index()));
         
    col = new ColumnHeader;
    //col.textAlign = dfl.base.HorizontalAlignment.CENTER;
    col.text = "  Program";
    col.width=65;
    lview.columns.add(col);
    //msgBox("lview col index = " ~ std.string.toString(col.index()));
   
    col = new ColumnHeader;
    //col.textAlign = dfl.base.HorizontalAlignment.CENTER;
    col.text = "                  Project";
    col.width=165;

so, I think, and I am no Windows Programming Expert, that when I double click on that item and it is suppose to fill all of this values,
Code:

    UniqueID              = lview.focusedItem.text; // set the record number;
    IDlabel.text          = UniqueID;
    ProjID.text           = lview.focusedItem.subItems.opIndex(0).text;   // ProjID
    subProjID.text        = lview.focusedItem.subItems.opIndex(1).text;   // subProjID
    Parent                = lview.focusedItem.subItems.opIndex(2).text;   // parent
    Children              = lview.focusedItem.subItems.opIndex(3).text;   // Children
    login                 = lview.focusedItem.subItems.opIndex(4).text;   // login
    txtCust.text          = lview.focusedItem.subItems.opIndex(5).text;   // Cust
    txtProj.text          = lview.focusedItem.subItems.opIndex(6).text;   //
    PClass.selectedIndex(PClassInt[lview.focusedItem.subItems.opIndex(7).text]);      // Class
    ProjBranch.selectedIndex(PSubClassInt[lview.focusedItem.subItems.opIndex(8).text]); // Class
    txtbDate.text         = lview.focusedItem.subItems.opIndex(9).text;   //
    txtdDate.text         = lview.focusedItem.subItems.opIndex(10).text;   //
    txteDate.text         = lview.focusedItem.subItems.opIndex(11).text;   //
    txtPM.text            = lview.focusedItem.subItems.opIndex(12).text;    //
    txtPMUK.text          = lview.focusedItem.subItems.opIndex(13).text;    //
    txtLang.text          = lview.focusedItem.subItems.opIndex(14).text;    //
    txtVendor.text        = lview.focusedItem.subItems.opIndex(15).text;    //
    vEmail.text           = lview.focusedItem.subItems.opIndex(16).text;    //
    txtInvoice.text       = lview.focusedItem.subItems.opIndex(17).text;    //
    txtProjFund.text      = lview.focusedItem.subItems.opIndex(18).text;    //
    PMTime.text           = lview.focusedItem.subItems.opIndex(19).text;    //
    txtA_No.text          = lview.focusedItem.subItems.opIndex(20).text;    //
    wDirDisplay.text      = lview.focusedItem.subItems.opIndex(21).text;    //
    BiliDirDisplay.text   = lview.focusedItem.subItems.opIndex(22).text;    //
    TMDirDisplay.text     = lview.focusedItem.subItems.opIndex(23).text;    //
    DeliDirDisplay.text   = lview.focusedItem.subItems.opIndex(24).text;    //
    txtPaid.text          = lview.focusedItem.subItems.opIndex(25).text;    //
    paidDate.text         = lview.focusedItem.subItems.opIndex(26).text;    //
    txtNotes.text         = lview.focusedItem.subItems.opIndex(27).text;    //
    txtStatus.text        = lview.focusedItem.subItems.opIndex(28).text;    //
    PMTime.text = calculatePMTime();


Some of those values are not set yet, and the program aborts. I could provide you with the code and data so that you can see it. It happens all the time. However, if I slowly click on the item, it happens less. But the faster I do it, the more it happens. Just trying to figure out if it is DDBI or DFL.

Any ideas?

I don't know what's wrong. Have you tried using a debugger?

windbg is quite easy to use, if you can work around its instability; compile with -debug -g, type windbg foo.exe, hit F5, trigger the problem in your program, and it should break at it. Use windbg's Window menu to show the Calls and anything else.
