    - Visible = False on Form_Closing... Hi, I have a MDIForm with some MDIChilds. When the user clicks on the "x" in the upper right corner, I don't want the MDIChild to be closed, but the property Visible = False. So far no problem: I do this useing the Form_Closing-event in which I typed: e.Cancel = True Me.Visibible = False But: When I Close the MDIParent, it wont shut down the whole application because of the fact that those MDIChilds cancel the closing! I tryed to put work with a boolean which is set to true when MDIParent is closed, and first evaluated in the MIDChild_Closing-event, but that doesn't work either, because of the fact that the Closing-event of the MDIChilds are fired before the Closing Event of the Parent... Anybody got any idea how to do this? Maybe with the Closed-event? This event comes after the Closing-event, but I can't find someting in ot to Cancel the closing of the form. I guess there must be a 'nicer' way to do this: Maybe by handling the click on the "x", and when it is clicked not to close etc etc... Hoping for your help and thanks a lot in advance, Pieter Tag: MouseUp event is raised when I double click my MDI form caption bar Tag: 64217

    - AnchorStyles conversion For a bitwise type like AnchorStyles the .NET runtime provides an easy way to convert this to a string (like "Top, Left"), but is there an easy way to convert it back again ? I've written my own method (see below) to do it but it strikes me that there may be a much simpler way ! protected static AnchorStyles DeserializeAnchor(string a) { AnchorStyles retval = AnchorStyles.None; if (a != "None") { if (a.IndexOf("Top") > -1) retval = retval | AnchorStyles.Top; if (a.IndexOf("Bottom") > -1) retval = retval | AnchorStyles.Bottom; if (a.IndexOf("Left") > -1) retval = retval | AnchorStyles.Left; if (a.IndexOf("Right") > -1) retval = retval | AnchorStyles.Right; } return retval; } Tag: MouseUp event is raised when I double click my MDI form caption bar Tag: 64215

    - IDesignerSerializationService Hi, I'm looking for examples, hints about a class which implements IDesignerSerializationService (ns: System.ComponentModel.Design.Serialization). I'm trying to create a DesignerHost. The Copy and Paste commands require that a IDesignerSerializationService object is added to the Services of the ServiceContainer. Without this it doesn't work. I can find any class which implements this interface, strange! Any help is appreciated. Regards, Fons Tag: MouseUp event is raised when I double click my MDI form caption bar Tag: 64212

    - HOW: Inherited forms and OnClick Armin wrote on the 1st of Jan as a reply to Lorne Smith "The designer creates the default procedure for events. Event procedures are usually not Public Overridable. IMO, you should not change the signature in the base class. If you want an overridable sub handling the Click, add an Overridable OnButtonClick procedure called in the event handler of the base class. In the derived class, override OnButtonClick". Question 1: Can anyone give an example (VB.NET if possible) on how to do that? I can't find any. Not even the MSDE example for OnClick is about OnClick. I've got a copule of books on Windows Forms (many of the good) and loads of online articles, the authors avoid going into inherited forms, which is a pity, since quite many questions in this discussion group seem to be about just that. Question 2: I'm successfully using override, but now I get confused: Lorne Smith writes: "when I put code in the sub, it was executed twice when I ran the form. Now I realised this is because both the base form and the inherited form are handling the event". WHY does both the base form and the inherited form execute the event? I thought override meant that the overriding method executes INSTEAD of the overridden, not that both are executed. Why would I use the override keyword if I want both to execute? But clearly Lorne is right in that both are executed. I've considered that an oddity, but it is by-design then.

    - Cannot change ListView first column text alignment I try to change the text alignment of the first column of a list view, ColumnHeader.TextAlign but seems it doesn't work. The first column is always default to left alignment, which is HorizontalAlignment.Left. I even try to insert the column in design time and set the column alignment to either center or right, but still the text displayed is left-aligned.

    - Using a .dll to display a form I have developed a .dll to display a form that controls a simple routine. Oddly, you can't use messagebox.show unless you do one of two things: either use an imports system.windows.forms or system.windows.forms.messagebox.show etc Now this is strange, because the form inherits as below: Inherits System.Windows.Forms.Form Why is this and what other problems may I expect to encounter?

    - Help! Microsoft.Win32.SystemEvents.WindowThreadProc eating CPU I have a windows forms application that occasionally eats 100% of the hosts system's CPU indefintely. If I break execution and selectively freeze threads, the culprit seems to be the thread named ".NET System Events". That thread is in a tight loop within SystemEvents.WindowThreadProc. I don't understand the disassembly, but it appears to be stuck completely within that method as I step through it. As I understand it, that thread is responsible for calling events when system properties change. I have hooked none of these events in my code, and like I said the thread appears to be looping entirely within the WindowThreadProc method. This happens most often when coming back from a Fast User Switch in XP or resuming from a suspended/hibernated state. What is going on?? How can I work around this? It's noticed by customers and makes us look bad. -Brian Tag: MouseUp event is raised when I double click my MDI form caption bar Tag: 64185

    - Bug in Windows Form Designer generated code (VS.NET 2003) Every time I make a change affecting a toolbar (e.g. adding or removing buttons), I loose the bitmap images at runtime. They are still displayed in the designer, but when the application runs, the toolbar appears blank with only separators visible. I determined that the problem is caused by the wrong location of the toolbar.Buttons.AddRange function in the auto-generated InitializeComponent function, which is placed before buttons are initialized. If I manually move the AddRange function call after the button initialization calls, it works fine, but the next time I make a change, I have to do it again. This is really irritating. Is this a known bug? Is there a fix for it? A better workaround? Thanks. Alek Tag: MouseUp event is raised when I double click my MDI form caption bar Tag: 64175

    - How to test a dialog Hi, Cannot find the dialog preview button in the form design mode (VS.NET 2003, C#).

    - Possibility to route different kind of events to only one handler? Hello, Does anybody know the possibility of routing different kind of events (Which has different EventArgs like Click and OnPaint for example) to only one handler sub? I'm creating a designer control to allow the end users to design a form.The user can drag new controls into this design surface and after the design I move those controls to a normal windows form..At this point, I want to get notified any of the events that those new controls will generate..And I don't have predefind event subs already in my code which I can link those controls... Is there any possibility for this? Thanks in Advance... Özden Tag: MouseUp event is raised when I double click my MDI form caption bar Tag: 64161

    - How to (easily) change the width of a single column in a DataGrid [VB.NET] I've run into a few posts on this, some with answers pointing to FAQs (like http://www.syncfusion.com/faq/winforms/search/754.asp), but I figured I'd go ahead and share the code I'm using. Basically, you need to set up a for loop through every column in your dataset and create a default action rigging up a DataGridColumnStyle for each. Then look for the cols that need special treatment and knock yourself out. You might insert a "case else" below and move the mappingname and headertext there to have a mutually exclusive default handler. ' Assumes you've got... ' Public dsTime As DataSet ' Public grdTime as DataGrid Dim myGridTableStyle As DataGridTableStyle = New DataGridTableStyle Dim TextCol As DataGridColumnStyle Dim dcTemp As DataColumn myGridTableStyle.MappingName = Me.dsTime.Tables(0).TableName For Each dcTemp In Me.dsTime.Tables(0).Columns TextCol = New DataGridTextBoxColumn ' I want my "description" column to be wider than the rest ' Select Case is overkill for one col, but is an easy place ' to expand to catch other columns Select Case dcTemp.ColumnName case "description" TextCol.Width = 250 End Select ' Everything else gets added with defaults, though you ' need to provide a name for the column to show up in ' the DataGrid. ' Seems to keep the default validators and everything ' by simply doing the below TextCol.MappingName = dcTemp.ColumnName TextCol.HeaderText = dcTemp.ColumnName myGridTableStyle.GridColumnStyles.Add(TextCol) Next ' add formatted tablestyle to the datagrid Me.grdTime.TableStyles.Add(myGridTableStyle) ' bind the datagrid Me.grdTime.DataSource = Me.dsTime.Tables(0) Ha, and if you search Google for something with "single" in it, like, say, [datagrid "single column"], prepare for some Google Ads to eHarmony.com & gotoCupid.com (though we all know GOTOs are Bad Things), etc. Tag: MouseUp event is raised when I double click my MDI form caption bar Tag: 64156

    - Control Focus issues Hello, A form with 3 textboxes and a button and the code below : Private Sub TextBox2_Enter fred() end sub Private Sub fred() TextBox3.focus End Private Sub TextBox3_enter console.writeline("Entering") End Private Sub TextBox3_Leave console.writeline("Leaving") end Private Sub Button1_Click TextBox2.focus End The intent here is to start with the focus in TextBox1 (no events), click the button. The button changes focus to TextBox2. The Enter event calls a routine that also shifts focus, this time to TextBox3. I would expect the output to be: Entering Instead I am getting Entering Leaving Entering This seems wrong and is causing some issues. In practice, tabbing to 'TextBox2' takes the place of the button click, but the end result is the same, a Leave event at the "wrong" time. mklapp Tag: MouseUp event is raised when I double click my MDI form caption bar Tag: 64154

    - How do you debug a Designer Error from Inherited forms I am getting an error in the Designer when trying inherit a form. Value cannot be null: Parameter Name dataSource now I do not use the Name dataSource in any of the inherited code so I am assuming that this is in the VS Designer code somewhere. The original base form comes up in the designer just fine. If I Ignore the designer and compile the new Inherited form it compiles and runs just fine. Is there a way of debugging what the designer is doing when it attempts to load the inherited form so I can see what is giving the designer grief.

I use the FindString with specifying a starting index within the ComboBox. I have tried the following but none seem to work: cmbBox.FindString(strWhat, cmbBox.FindString(strWhat)) - :( don't work For example: if Items count is 1 - I have only one item in the items collection, cmbBox.FindString(strWhat) return 0 - this only one item starts with strWhat With FindString(strWhat, 0) i receive ArgumentOutOfRangeException error... Why, if error condition is: "The startIndex is greater than the last index in the collection."???? How I can do this?

    - WinForms UserControl problem at VS.NET design view Hi, I'm working on a Win form application which is being developed in VB.Net. I have created few User Controls quite some time back and implemented them successfully. Now the problem is, I'm not able to use UserControls using my VS.NET IDE. When I tried to drag and place the user controls on WinForm (from Toolbox), it shows an error saying "An exception occurred while trying to create an instance of Classname.UserControlName. The exception was 'Value cannot be null. Parameter name:path'". And another strange problem is when I tried to open my existing solution, the controls are missing and an error is shown like "The Variable 'UserControlName' is either undeclared or was never assigned. Could some one please help on this ASAP? Your help is muchhhly appriciated as we are closed to the deadline.

    - SQLDataAdapter SP Generation Hi, I have created an SQLDataAdapter component on my vb.net winform project and stepped through the wizard. In my SQL Database I have a table with fields using user defined data types and not the base data types. The problem is that when the stored procedure gets created by the adapter the parameter's data types did not follow the data type of the table I used in the wizard. Is there any solution on how I could use my user defined data types in my SP, autogenerated by the adapter, w/o actually modifying the SP after running the wizard? Appreciate any help. Thanks.

    - Suggestion for implementing controls based on rules Hi everyone; We have a problem in our compact framework client-server application for which we would require your valuable suggestions. Problem: There are controls in the application user interface that has to be loaded based on rules / transaction codes else they are not displayed at all, hence the controls won't be there at design time but they would have to be created and placed at run time.Hence a elegant and simple solution has to be designed to meet out the requirements. Solution: We are leaning towards getting all valid transaction codes from the database and loading into memory at the start of the application. When a form is created for the first time,the form and all the form controls are created based on the transaction codes.The form is then saved into a form factory. If that form is required again then it is loaded from the form factory. I would appreciate some comments or suggestions to this approach.

    - Load event firing twice for one form instance I have a form which I want to show modally; it's a fairly old form that's been ported up several versions of VB, and I'd like to keep its rewriting to a minimum. Basically, it is used in this sequence: 1. The form is shown. The Form_Load event does some initialization. 2. Further parameters are passed to this form. 3. We actually need this form to be modal, so we hide it and show it again modally. 4. Stuff happens on the form based on the parameters passed in, etc. (The VB.NET code for this is below.) However, I've discovered that calling ShowDialog() in step #3 fires off the Form_Load event a second time, even though it's the same object instance. Does any instance of showing a form fire this event? (My problem here is that the Form_Load initialization should only happen once. I could use an already_initialized flag, but that's horribly messy; if I have to, I'd rather pass Foo in the constructor and hold onto it through the Form_Load process.) --Caitlin Shaw **Code** Private WithEvents frmThing As ThingForm Public Sub DoThatThingWithFoo(Foo as Object) 'Create the thing and set it up frmThing = New ThingForm() frmThing.Show() frmThing.DoSomeSetup(Foo) 'Really, though, we want this thing to be modal frmThing.Hide() frmThing.ShowDialog() 'Good, that's done frmThing.Dispose() End Sub Tag: MouseUp event is raised when I double click my MDI form caption bar Tag: 64125

    - NotifyIcon is greyscale under Windows 2000 Doing developing under Windows XP,VS.NET 2003,.NET 1.1 Framework. Assign notifyIcon an icon *.ico file. Appears fine (color) in task tray when running under windows XP. When I run on Win 2000 test machine with .NET 1.1 Framework installed, the app runs fine but the task tray icon is greyscale, rather than color. Thinking it was some glitch with this particular icon, I've tried dozens of different icons (from inside shell32.dll) with the same results. Anybody have any idea what this is?

I thought about using Isolated Storage for this and saving the User's Settings to a xml config file, but I can't save to Isolated Storage with the Default Security Settings. Does anyone have any other suggestions I can try?

    - adding items to forms' resource files Please let me know if there is a better way to do this. I have set the Localizable property of my forms to true, meaning of course that it will persist the properties of the controls of my forms in the resource file for that form. But my question is, how do I add additional properties for that form to the resource file? For instance, I have error messages, tooltips, log messages, etc., associated with each form. It makes sense to me to be able to add those to the form's resource file and then to be able to reference them from within code (using the resource variable that VS generates). However when I add them, after I make changes to the form in Visual Studio, the items I added are gone. I am aware that I can create a new resource file and reference from there but I'd like to avoid that since there is already a resource file for each form created.

    - Standard and other toolbar icons/bitmaps I'm being dead thick, but I can't get my head around this: Where can I get standard toolbar icons like Open, Save, Print etc from? Should I embed them in my app or can I assume that any system will have them? How does each version of WIndows differ - do I need to know what version the user is running and pick icons accordingly? I've pulled a bunch of other icons from dlls, and want to use some. However they have white backgrounds both in the Image Editor and when displayed. The host ImageList TransparentColor property doesn't make a difference. Changing the bitmap background from Opaque to Transparent doesn't make a difference. There's nothing in any of the .NET books I have, and I can't find anything online. What am I missing? Tag: MouseUp event is raised when I double click my MDI form caption bar Tag: 64108

    - Calling Dispose on form variables. Hello All, I've a doubt regarding calling Dispose() method on the controls of a form. I've a simple MDI form. On a click of a menuItem I instantiate a new modeless form. As per a prior message posted (http://blogs.gotdotnet.com/rprabhu/permalink.aspx/af94ee11 -5488-4ff0-bd5b-d7b41a0d0ebf), modeless forms are disposed whenever they are closed. This is also happening in my case as the dispose method is being called. So far so good. But I noticed that the code to call Dispose() for all the controls in this modeless form is not generated by VS. Only some of the controls(e.g. System.Windows.Forms.Timer) which are being added to 'IContainer components' member variable of the forms are being Disposed. Rest for all other controls, I've to call the Dispose method manually. I've no problems in doing this, but I wanted to know why this is done? The controls in this modeless form are custom control and all implement a common application specific interface. When I try to call their Dispose methods, some of the controls throw this exception Exception : "InvalidOperationExcepiton" Message : Cannot call Invoke or InvokeAsync on a control until the window handle has been created. StacKTrace : at System.Windows.Forms.Control.MarshaledInvoke(Control caller, Delegate method, Object[] args, Boolean synchronous) at System.Windows.Forms.Control.BeginInvoke(Delegate method, Object[] args) at System.Windows.Forms.Control.BeginInvoke(Delegate method) at System.Windows.Forms.DataGrid.OnLeave(EventArgs e) at System.Windows.Forms.Control.NotifyLeave() at System.Windows.Forms.ContainerControl.UpdateFocusedControl () I'm not able to make it out, what this exception is, and how can I handle. Can anyone help me out in both of my doubts? Thanx in Advance. Mahesh. Tag: MouseUp event is raised when I double click my MDI form caption bar Tag: 64093

Hi everybody:

I have a MDI application which has MDI forms containing every form a
list view that shows files and folders like Windows Explorer.

I have my own implementation of the context menu, so, I
programatically show it when the mouseUp event is raised over the list
view and the mouse button is the right button (quite obvious).

My problem occurs when I show the context menu, and after I maximize
the MDI form double-clicking the caption bar: My context menu is shown
again because the mouse up of the list view is raised!!!!

I searched in this group and I did not found similar problems and I
have no idea to solve this problem because the MouseEventArgs object
that my OnMouseUp() method receives is valid.

Any help will be very useful. Thanks in advance

Ernesto
