• kevin D. white Microsoft Forms Application 2003 .NET how to 'read only' view a text file?

  I am new to this development environment, though not new to C++ or the Windows IDE. My task is to develop an ASCII file viewer. I am having difficulty finding an object that allows me to display the contents of an ascii file in 'read only' format in a Window. These files can be very large. I need to be able to scroll through the lines, and have a Mouse Click event tell me which line a user wants to see more information about. Thanks for your assistance. Steve Excellent, I will investigate all of them to see which fits best. Thank you for the guidance.

• Adrigo Gallus it is possible to uncheck all items in a checkedlistbox whit one statment??

  I've tried to do this but it doesn''t work " CheckedListBox1.ClearSelected()" This is off topic for the Visual Basic General forum, moving to the Windows Forms General forum. thanks, that will help. Hi, Select and Check are two different concepts in the checkedlistbox. ClearSelected will not uncheck the items. To uncheck all items that are checked, use this code foreach ( int i in checkedListBox1.CheckedIndices) { checkedListBox1.SetItemCheckState(i, CheckState.Unchecked); } gqlu wrote: Hi, Select and Check are two different concepts in the checkedlistbox.

• JBondITW Problems with PrintPreviewDialog

  I have the following code: try { printPreviewDialog.ShowDialog(); } catch (InvalidPrinterException e) { MessageBox.Show(e.Message); } When it runs on computer where no printers installed, I get error message as expected.

• SQLScott Stop MDI Child menu from merging with MDI Parent menu

  Is there a way to stop the MDI child main menu items from merging with the menu items in the MDI parent Thank you for the reply Chris. I should have been more clear in my question. Using the Remove MergeType setting does indeed stop the child menu from merging with the parent menu. However it also hides the menu from the child form. Is there a way to keep the menu on the child form and the menu on the parent form and still display the child as an MDI child Unless you implement your own menu system you can not display a MDIchild with a menu. You can try setting the Parent window to IsMdiContainer = false, then use the Controls.Add(child form) to add the forms. T ...Show All

  Hi all I have a user control in which i have many sub web controls placed How can i access, say a dropdownlist control or a linkbutton click event in the usercontrol from an aspx page code behind Is this possible Can anyone please give some idea Thanks The general rule of thumb is to either expose the control(s) as public members of the user control to provide unrestricted access or to create a few properties and/or methods that give a user of the user control only the access you want them to have to the sub controls.

• Rob Ski Time issues

  I need to take a look at the content of some DataTable(s) I download from SQL Server in a purely debug situation. I decided to use DataView object for it. I improvised the following code: DataViewManager mng = new DataViewManager ( sqlDatSet ); DataView dtview = mng.CreateDataView ( sqlDatSet.Tables[jj] ); dtview.BeginInit ( ); The jj integer is the index of a particular DataTable in a DataSet and is found in a for loop. I expected a primitive form with a Table View displayng my records to show up. Is it not a reasonable expectation Nothing like this happened. The DataView remained an internal object. If I cannot get a good look at what is present in the tables I download I will be facing a cumbersome task of printing the stuff ou ...Show All
