 - opacity property not working Let me start by saying that I have successfully used the Form.Opacity property in many other windows in my application. I have several forms that inherit from a base class form that do not seem to respond to the Opacity property. I've tried setting it in the designer and programatically. I've inspected the property in the debugger and it shows up at Opacity = .75, as desired. As I said, I can successfully put other windows that have varying levels of transparency up at the same time which work just fine. Any help would be appreciated. Thanks, Davey Tag: ComboBox Bug Tag: 79103

 - Application crash caused by ToolTip.RemoveAll. If you install .Net Framework 1.1 SP 1 or .Net Framework 1.0 SP 3, you could start getting random application crashes if you use ToolTip.RemoveAll. The ToolTip control has had a memory leak since 1.0. To solve this, we put into the each form's close event the ToolTip.RemoveAll() statement. ToolTip.Dispose() didn't fix the memory leak. When SP 1 came out our application started randomly crashing. Sometimes it took five minutes, sometimes as long as five hours. Microsoft finally chased it down to the RemoveAll statement that had been changed. We switched to Dispose and the crashes stopped. They had also fixed Dispose so that it cleaned up the memory leak (they didn't actually fix the control leaking, just the Dispose method). This issue is now that if you don't have SP 1 installed, the ToolTip control will leak. Given the choices I would much rather have the leak than the crash!!! Tag: ComboBox Bug Tag: 79101

 - Effective exception handling I would like to know what people are using for effective exception handling in windows forms applications? I ideally want to log all exceptions raised by my application without try catch blocks in every method. The only way I can seen to do this is by subscribing to both the Application.ThreadException and the AppDomain.UnhandledException. Any suggestions on what the best way to achieve this? Many thanks DT Tag: ComboBox Bug Tag: 79098

 - Combo box controls in Windows Applications render list items blank Several of our windows applications are rendering the items created in controls like ComboBox controls as blank. The items are actually in the collection but the window that is displayed what the ComboBox is open shows all items as blank. We also noticed that a simple operation like MessageBox.Show("Hello World", "My Application") renders the "OK" as blank also (no text is displayed) and the Text property for the message being displayed (Hello World) is also blank. Is there any issue reported with the System.String class and the XP SP2? Any idea will be appreciated. Thank you in advance. Tag: ComboBox Bug Tag: 79096

 - accessing form controls in Vb.net Hi all, I have created two forms namely form1 and form2 in my application. I created a button "start" in form1. When this button is clicked form2 is initialised as a child object and an instance of form2 is displayed at the same time hiding form1 from the user. In form2 I have an "exit" button, which when clicked invokes "me.close()". This closes form2 which is active. but still the program is not stopped, Because form1 was the startup object and it is been hidden. So the hidden form1 is alive and hence the program does not stop and the user is not seeing anything on his screen.Please tell me a way to hide form1 when form2 is invoked and at the same time when form2 is closed the entire program should be closed. With smiles, Deepa. Tag: ComboBox Bug Tag: 79090

 - SizeGrip Active Area I have a number of resizable windows in my application. Some of them are displayed as modal dialogs while others are displayed as normal windows. The ones that appear as dialogs show the size grip at the bottom right corner. The active area over this size grip is a rectangle that includes the size grip as displayed. When I display a normal window, the size grip does not display. Even if I set the SizeGripStyle property to Show, the active area remains the same (just near the border). I would expect the active area to be larger as it is in the modal dialog case. Is there a way to make the active area larger when the size grip is displayed? It is confusing to see a size grip icon, move your mouse over it, and then not be able to resize the window because you are not in the active area. Thanks, Rangi Keen Tag: ComboBox Bug Tag: 79077

 - mshtml and the click event inside of a windows service. I have an application that uses the Ax web browser object. When I call the IHTMLElement.click() method on an input button (<input type="submit"> or <input type="button">), the click fires appropriately, if I'm running it from a windows forms based application. However, when I run the EXACT same code under a windows service, either as a logged in user or as the local system account, the click fails to process. Clicking on other elements (like <a>) works. I've tried submitting the form directly, in cases where a submit occurs, but can't do that either. Both GET and POST actions fail. What am I doing wrong? Is there something that prohibits the onclick event from firing for buttons when running as a service? Am I missing something? Robert Tag: ComboBox Bug Tag: 79074

 - ArgumentOutOfRangeException adding items to a CheckedListBox. Create a new form, add a CheckedListBox to it. Add the following code to the form's Load event: private void Form1_Load(object sender, System.EventArgs e) { this.checkedListBox1.BeginUpdate(); this.checkedListBox1.Sorted = true; try { this.checkedListBox1.Items.Add("ABC"); this.checkedListBox1.Items.Add("def", true); } finally { this.checkedListBox1.EndUpdate(); } } If the CheckedListBox is sorted, and you are between a BeginUpdate and EndUpdate, then an ArgumentOutOfRangeException will be thrown if you try to add an item to the list and set it's checked state at the same time. Getting rid of the BeginUpdate/EndUpdate or Sorted property "fixes" this. Tag: ComboBox Bug Tag: 79066

 - Building a windows forms "spy" Hi I am about to develop a program that scans the text properties of a number of text boxes in another program and copies them to the clipboard. The software that I want to scan has no function for printing on a printer, and therefore I am building this extension to enable simple printouts. The program I am scanning is built in C#. My program should be built in C# too. I do not know the names of the textboxes, so to begin with I need to be able to get the names of the textboxes to scan. These names will probably not change, so when have gotten these names I can add them to the code. I know the name of the form (or at least the caption of the form) that the textboxes are in. I have no need for changing the properties of the textboxes either. Does anyone have some simple code that can help me getting started? Thanks Jonas Bergman Tag: ComboBox Bug Tag: 79044

 - Help!!! Visual Inheritance...... Hi, I want to know if I'm doing something wrong. I'm inheriting frmChild from frmBase in Project1. frmBase is referring to its MdiParent in a function call from Form_Resize event. When I try to open the designer for the frmChild it throws an exception for this, saying "Object reference not set to an instance of an object." Why is this happening. Does that mean I cannot use any runtime instanciation in a base form? Or do I have to turn something off? Why is the code executing in the designer. If I give a message box in the base form, it pops up when I am loading the Child form!!!!! Any help is appreciated.. Thanx, Debi Tag: ComboBox Bug Tag: 79021

 - Why does transparency only work sometimes with 32 bit color depth? I have an application that uses transparency. My video settings are 1600x1200 and 32 bit color. I can make the main dialog transparent but other controls and child windows are not transparent, I see the colored box around my control. If I switch my color depth to 16 bit everything is fine. Why does it work on some forms but not others. I can even make my main form transparent and drop a custom control that has transparency set. The main form goes transparent but the custom control has a blue (my transparent color) box around it. Again if I switch color depth it works fine. I heard that somewhere in the .NET documentation it says transparency is not supported under 32 bit color. I have a hard time believing this. Are there any computers that don't come in 32 bit color mode anymore? Jim Tag: ComboBox Bug Tag: 79008

 - Memory leak - Forms with Owners I have created a project that has two forms. Form1 has a button which runs the following code: private void button1_Click(object sender, System.EventArgs e) { Form2 f = new Form2(); f.Owner = this; f.Show(); f.Close(); this.RemoveOwnedForm(f); f.Dispose(); f = null; } Using .NET Memory Profiler (http://www.scitech.se/memprofiler) I am able to see that Form2 is not disposed. This seems to be a huge issue. Has anyone experienced this problem? Is there a workaround? Have I done something incorrectly? If I remove the line where the Owner is set, there is no problem with Form2 being Disposed. Thanks, Nate Tag: ComboBox Bug Tag: 79001

 - exceptionless exceptions in masked edit box Hello, I encountered something to that, even though I have worked it out for myself, I thought should be passed on. While I was debugging an event handler (Validating) for a masked edit box, I suddenly found myself 'back in the UI'. The line of code that precipitated the surprise exit from the event handler to the UI happened to generate a null reference exception, but no detectable exception was reported (either in the IDE debug run or in the released program). The line of code was not in a try/catch block (there are others in the handler and, when appropriate, they are triggered). It was the true source of the bug being worked on, but it was not detected until much later in the code because as far as anyone knew the event handler validated the control quite nicely. I figure that whatever 'hidden' code calls the event handler does so from within its own try/catch block. When it encounterd this particular exception, it simply returned execution to the 'UI thread' (no explicit multi-threading was used in the program, that descriptive phrase was intended to limit verbiage (looks like I failed there)). I don't know if this is just an issue with the masked edit box or with more controls. Thought you'd like to know, mklapp Tag: ComboBox Bug Tag: 78983

 - drawing text, autosizing textbox, flickering ... Hi (VS.Net 2003 + SP), how to make anchored textboxes, toolbars or statusbar not to flicker on resize? And one more thing, I wanted to make multiline textbox to autosize in height and width. Since autosizing is done only in singleline, I used prefferedSize= Graphics.MeasureString(control.text, control.font) to get required size. But after resizing textbox, I saw that it is too wide and height is less than required. So I tried to paint text myself. Then I saw, that everyline of that text is painted differently (using standart font, same text on every line), changing text to Arial 9pt, helped a bit. But anyway it is too wide and height is less than required for textbox. How to implement full autosizing for textbox? Tag: ComboBox Bug Tag: 78951

 - Unable to keep form on top I'm trying to create a screensaver using managed directx, but the same happens with the wizard generated screensaver project in VC# 2005. Any window set to "always on top" is not getting obscured, like the standard windows screensavers can. I've tried setting the presentparams for the device constructor to "windowed=false". I've set the form property Toplevel=true, topmost=true, and called .bringtofront(). Anybody know what I'm missing? Tag: ComboBox Bug Tag: 78934

 - Controls created on one thread cannot be parented to a control on a different thread I am trying to make a window that pops up, to show that my application is busy. I want it to be able to be called from anywhere, any thread, so I put it as a static method in a class. Code listed below. The problem is, no matter what I can think of doing, I get the following exception: "Controls created on one thread cannot be parented to a control on a different thread" Trace: at System.Windows.Forms.Control.MarshaledInvoke(Control caller, Delegate method, Object[] args, Boolean synchronous) at System.Windows.Forms.Control.Invoke(Delegate method, Object[] args) at UI.Waiter.Busy(Object waitOn) or i used to get this with a slightly different configuration (same exception): Trace: at System.Windows.Forms.ControlCollection.Add(Control value) at System.Windows.Forms.ControlCollection.Add(Control value) at UI.Controls.WaitForm.InitializeComponent() at UI.Controls.WaitForm..ctor() at UI.Waiter..cctor() Anyone got any ideas... or am i going about it the wrong way all together!?

I have a Combobox with the following properties:
Me.cboAddServices.DropDownStyle =
System.Windows.Forms.ComboBoxStyle.DropDownList
Me.cboAddServices.DropDownWidth = 240
Me.cboAddServices.Location = New System.Drawing.Point(32, 16)
Me.cboAddServices.Name = "cboAddServices"
Me.cboAddServices.Size = New System.Drawing.Size(225, 21)
Me.cboAddServices.TabIndex = 60

This comboBox in placed inside a groupBox that is on a TabControl. The
comboBox control is populated through the datasource property by a dataSet
table.

I have seen many problem related to tabControls & comboBoxes but none are
like mine. My problem is that when I select a listItem in the comboBox it
reselects the first item. After a second attempt on selecting the SAME item
it highlights it. This has to be done for each listItem in order to select it.

Any ideas?
