    - Handle form closing I have an MDI form containing child forms. I want to handle form closing to display a confirmation message when a form is closed or when the main form is closed. However, the Closing even of the child forms is raised before the Closing event of the MDI form when you close the MDI form. So, if I catch the Closing event of the child forms and display a message, then catch the Closing even of the main form, then I get 2 messages displayed. Is there a way to know, when a child form is being closed, wether the user closed the child form or the mdi form? Thanks Etienne Tag: Master Detail in crystal report Tag: 77897

    - Large Fonts not scaling correctly on tab control. I have a problem which I have been able to reproduce in a very simple project. I have a form with a single tabcontrol control with two tab pages. The tabcontrol's Anchor property is set to Top, Left, Bottom, Right (all 4 directions). On each tabpage, I have a DataGrid. Each DataGrid's Anchor property is also set to Top, Left, Bottom, Right. I developed this simple application with my System's DPI setting set to Normal Size (96) and everything worked perfectly. The problem came, however, when I changed my DPI setting to Large (120). The datagrid on the first tabpage (index 0) did not have the correct size (too large). On the second tabpage (and any others that were present in subsequent tests), everything was sized correctly. The same problem happens in reverse (developing in Large and moving to Normal). My workaround was to create an empty tabpage at the beginning of the set and remove it from the tabcontrol's TabPages collection during the form's load event handler. I could have also not used anchor and changed the control's width during the form's resize event. Any non-hack solution or explanation would be appreciated.

    - Datagrid Empty Set Here is one I am stuggling with: I have a project I'm developing in VB .NET. I have a datagrid in a window with two columns. The first column is readonly and the second column is not and initialized with Zero's. The values in column two must be numeric. How do I prevent the user from leaving an Empty set in the cell? I already have a handler that ensures the user enters numeric values. I would like to default to Zero if the user deletes a value or enters an empty set.

    - Negative Numbers? Hello, I have some textboxes that are doing addition: Dim AString As Double AString = Convert.ToDouble(TextBox1.Text) - Convert.To(DoubleTextBox2.Text) TextBox3.Text = AString.ToString("#,##0.00;(#,##0.00);0.00") When the result is negative it is displayed as "(46)" or whatever the value is. This makes it impossible to test for a negative number to make further additions: TextBox5.text = Convert.ToDouble(TextBox3.text) + Convert.ToDouble(Textbox4.text) Is there a work-around for this? I must have negative numbers that can be added together. Thanks, Chuck Tag: Master Detail in crystal report Tag: 77885

    - ComboBox woes I need help solving a couple of problems (and learning a couple of concepts) involving ComboBox columns in my DataGrid. The first problem involves my custom ComboBoxColumn class. I don't have experience making custom classes so I downloaded some code. From what I've read, it's pretty standard for adding a ComboBox column. It overrides the Edit, SetColumnValueAtRow, and GetColumnValueAtRow subroutines. It works great, but it doesn't allow the user to type in custom items in the combobox. Anything you type in just gets ignored. I want users to be able to add new items to the database through the comboboxes. I don't understand all of this code, though, so I'm not sure how to do this. The comboboxes are bound to datatables, so when the changes are committed I just need to add a new row with the new text to the datatable. Then when my "Update Database" button is clicked, the table changes will get sent to the database. It looks like maybe SetColumnValueatRow is the key subroutine? The second problem involves the relationship between my query form and my display form. My query form is a series of ListBoxes bound to certain DataTables in my DataSet. But before I fill the tables from the database, I add an item called "All" to the tables so that I can select all items in the listbox for query purposes. The problem is that the comboboxes in my datagrid are bound to the same tables, so I have to remove the "All" item before displaying the datagrid or else "All" will be displayed as a selectable item in the combobox. This works fine if you use the query form once, but if the user clicks the "Back" button on the display form I have to put the "All" item back into the tables for use in the query form. But inserting an item in a datatable that is already filled doesn't seem to be as trivial as adding a row to a blank table. Obviously I want "All" to be the first item in the list, so I can't just tack it on to the end. Right now I have to clear the tables and refill them, which is taking about 15 seconds. I guess one solution is to just make copies of the tables and put "All" at the first index in one of them and bind each listbox and combobox to different tables, but it seems there should be a more elegant solution. Is there a syntax for inserting a custom item in a datatable at index 0? Tag: Master Detail in crystal report Tag: 77878

    - Form.Closing event Hello: I have a Form that override the OnClosing method to make some actions before the window is closed, but does not set the Cancel property to let the form close, assuming that its value by default is false. All was working fine until I install the service pack 1 of the .Net framework 1.1. The Cancel property is true and the form remains open. I change my code to assign the value to false, but I want to know if there is a reason for this behavior. I check on a new application calling the Close(); method, or clicking on the close button, and try also with the application main window and with another window, modal and modeless, in all cases, Cancel property was set to false.

    - Distinguish Home key from NumPad Home key? Hi all, Does anyone know if it is possible to distinguish between a user pressing the dedicated Home key versus the Home key on the number pad (NumPad 7 with NumLock off)? I'm working in VB.NET on WinXP Pro. The standard KeyPress/Down/Up events return identical key codes. I've tried the API GetKeyboardState call and I've even tried keyboard hooks as described in http://www.developer.com/net/net/article.php/11087_2193301_1/ I'm able to accurately determine state of the NumLock key, but NumPad 7 with the NumLock off appears to generate the same key code as the dedicated Home key. Has anyone had any experience in this area? I've been looking at this issue for a while, so it's possible I'm overlooking something simple :) Thanks, Jim Tag: Master Detail in crystal report Tag: 77865

    - Forms designer hangs when control added (combobox or listbox so far) hi. i've searched everywhere for an answer to this problem, and the closest thing i've found is a report from someone else with the same problem. using vb.net, ver 2003. this happened before installing the latest .net framework update and after. i have a simple windows forms app. a couple of forms, using textboxes, tabgroups, labels, and buttons...nothing complex. i try adding a combobox control to this form, and the IDE hangs indefinitely (need to end task it). the first time i had this problem was a couple of months ago with a larger, more complex application... i had created some custom controls that inherited from some of the base windows.forms controls, and was having all sorts of fun with the designer not being able to "get it", refusing to render forms, hanging if it did manage to open a form, and so on. the visual inheritance problem was easily fixed by simply building the project, though i still had to be careful what controls i selected on a form in design time in case it hung. since then i've tried to do as much "visual" stuff as possible in the code view, but i've encountered this again and can't get to the bottom of it. i've just run another vs.net process and attached the debugger to my hanging one. i've noticed that the hanging occurs when i move the mouse off the form (say, over to the properties dock) but having said that i've previously noticed that the hang happens after a small period of time, no matter what you do with the mouse. so yeah, i've got a nice bit of disassembled code that's stuck in a loop, details: Address: System.Windows.Forms.NativeWindow.Callback (^this is what's looping) it calls: System.Windows.Forms.Message.Create returns to NativeWindow.Callback, then calls: System.Windows.Forms.Design.ControlDesigner.ChildSubClass.WndProc which calls: System.Windows.Forms.Design.ControlDesigner.get_DesignerTarget System.Windows.Forms.Design.ControlDesigner.set_DesignerTarget does anyone have any ideas? any pointers in the right direction would help a lot!

    - Maintaining and Using App Login details Hi, I'm developing an Windows forms based app that will draw data from a SQL Server 2000 system, that is set to use SQL Authentication (i.e. connection string must pass uname:pword). Given that various forms will need to use a SQL connection to generate data for data grid's etc ... how can I pass this authentication information around the various forms? A solution is to start the application from a VB.NET class, that has a shared member with the connection string (set once the user completes the login) Or create a shared connection object? Should I create a new connection object for each form? I currently test whether the login credentials are correct by enclosing within a try..catch clause an attempt to open and close a connection, failure will indicate invalid details (or perhaps a dead SQL Server!) ... any improvements on this? I assume that when using the form designer in VS.NET that if I manually program the connection (i.e. outside the section of code written by VS.NET ) that I can point the adapters/datasets etc. to the required connection. There are a few questions here ... but I've not so far found any answers here, on Google or elsewhere :( ! Thanks in advance for help Tag: Master Detail in crystal report Tag: 77795

    - KeyUp event routing issues in Windows Forms. I believe I have found a bug in how keyboard events are routed in Windows Forms. I am not sure if this is a bug or how to work around it. MessageBoxes (MessageBox.Show) that are opened over top of a form end up routing their KeyUp events to the active control beneath the messagebox. For example, if I have a TextBox control focused on a form, and I open a message box, pressing "enter" to close the message box causes the TextBox control to receive a KeyUp event for the enter that was pressed in the dialog! It's almost as though the message is getting routed to the incorrect location. To reproduce this problem, create a new Windows Application (C#) project in Visual Studio 2003 (.NET 1.1. The issue occurs in the service pack edition as well). Drop a TextBox control onto the form's canvas from the toolbox. The bug occurs in any control that can receive focus, but in this case I will use a TextBox. Add a MouseUp event handler to the textbox with the following code: private void textBox1_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e) { MessageBox.Show("The textbox was clicked. Pressing 'enter' on this dialog will cause the keyboard event to be incorrectly routed to the text box."); } Then add a KeyUp event handler to the textbox with the following code: private void textBox1_KeyUp(object sender, System.Windows.Forms.KeyEventArgs e) { if (e.KeyCode == Keys.Enter) { MessageBox.Show("An Enter KeyUp event was received by the text box. If you pressed enter to close the dialog, this message was incorrectly received! Pressing enter again on this messagebox will cause an endless loop!"); } } Save the project and then run the application. Click on the textbox to cause the messagebox to appear, then press the enter key while the messagebox is focused. The KeyUp event was routed to the wrong location, possibly causing undesired behavior! I noticed this bug with we were writing "ESC" key handling code in our application to close documents. A messagebox would appear, and if the user pressed "ESC" to close the messagebox, the ESC key event would get routed to the document, which would cause it to close - definately not correct behavior! :( I don't have the KeyPreview property enabled on the form. Is there any work around for this? KeyPress and KeyDown don't get executed however. I suppose I could move the code into the KeyDown event. Tag: Master Detail in crystal report Tag: 77785

At some point the user could click <Make Scenario> and all the corresponding input for testing would be generated. What I'm wondering is anyone knows of some source code in C# for a similar kind of editor that might serve as a starting point. Even a custom timeline control that could be replicated would be a good help. Thanks! Tag: Master Detail in crystal report Tag: 77766

    - Disable Task Manager I'm trying to figure out how to PROGRAMMATICALLY disable the Task Manager while logged in as a "non-administrator" user (only belongs to the "Users" group). I know I can programmatically disable the Task Manager by having my app write a 1 to the registry key HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System. Unfortunatley this only works, though, if the user who is running the app is logged in as an Administrator. When I try to run the app as a just a regular "non-administrator" User I am not able to write to the registry! So... Is it possible to do this? If so how?

    - Detecting idle time from a .Net application I'm having a lot of trouble finding a universal and stable solution to the problem of detecting a session's idle time. I have a .Net application that runs in the system tray, much like many of the messenger services out there. From what I've read in the newsgroups, there are several mechanisms that I can try, but the biggest problem is that I have to get it working on Win98, WinME, Win2K and WinXP. The options I've found are: 1) On a timer, use GetLastInputInfo to check the last input event No good. This requires Win2K and up - I need to run on 98 and ME 2) Add a low-level mouse and keyboard hook in my .Net application using SetWindowsHookEx specifying the hooks WH_MOUSE_LL and WH_KEYBOARD_LL Again, works great in XP, but WH_MOUSE_LL and WH_KEYBOARD_LL are incompatible with 98 andME 3) Add a global mouse and keyboard hook in an external DLL using SetWindowHookEx and WH_MOUSE and WH_KEYBOARD This work fine accross all platforms, but for some reason whenever the screensaver kicks in, my hook stops receiving events. So my question is, is there another solution I should try, or is there something I should be aware of that could get any of the above solutions to work?

    - delete selected rows from a datagrid I have a datagrid whose datasource is a datatable. I want the user to select (multiple) rows in the datagrid, press a button and have the selected rows deleted. Iterating through the rows in the datagrid and testing to see if each is selected and then deleting the associated datarow from the datatable is probably inefficient but nevertheless doesn't work because the selected rows in the datagrid are reset as soon as the first record is deleted from the datatable. Is there an obviously correct method for doing this? Tag: Master Detail in crystal report Tag: 77763

    - Newbie: Dataset - ComboBox synchronization Hello, I have two questions involving Datasets and populating ComboBoxes and other controls with them. 1) Two cmbboxes are populated by two different fields of the same table and, of course, synchronized. However the second field is not required in the DB and missing contents sometimes. Ex: Field1 Field2 john 1990 mary paul anna mario 1967 james .....,etc. So when the user scrols through cmbField1 there is no problem, however if you want to scroll through the year there are big gaps that you go through because there is no contents there. Is there a way to get around that and STILL keep the cmb Boxes synchronized? 2) Now, after having the above from the same table and trying to get *Related* info from another table in my DB (of course still synchronized with the other two controls) I added a second table to the dataset with the INNER JOIN info. I access the new field by : Table1.field3. But field3 belongs to Table2 !!! not Table1! Is this normal? People say it's not a good idea to add more than one table in the same dataset. If this is true how can I get Relational information that is still synchronized? (i.e. fields 1 and 2 from Table1 and field 3 from Table 2) The fact that I get what I want is not enough. I need to know if it's the right way for my case and if there is s better way. Any help/feedback would be Greately appreciated. _steve_ Tag: Master Detail in crystal report Tag: 77762

    - Combo Box Display Member is reset Context: setting a collection of business objects as the DataSourceof a ComboBox. The collection itself extends CollectionBase, and has public properties exposing the desired display and value members. In this particular case, the display and value member is "Value". Prior to setting the combo box datasource, the display member and value member properties are set, then the datasource itself is set. So, before setting the DataSource, the DisplayMember = "Value", but after setting the DataSource, the DisplayMember reverts to "". To put a twist on the issue, the second time that the DataSource is set, everything works as it should... Thanks for any and all input. -- Sancerre Tag: Master Detail in crystal report Tag: 77758
