    - WS_EX_LAYERED/LockWindowUpdate problem Hello, I use LockWindowUpdate() API function through P/invoke to prevent updating form content while updating/removing/adding something in form (child controls). Despite of the bug in W2k (Q270624, Layered Windows Disappear During Calls to the LockWindowUpdate() Function) I do something like this: 1. Remove WS_EX_LAYERED attribute from form through SetWindowLong API 2. Call LockWindowUpdate 3. some updates (adding/removing child controls through standard .NET methods) 4. Call LockWindowUpdate - for form unlock 5. set back WS_EX_LAYERED flag on a form 6. redraw form but on W2k after a point 5 form disappears and I cannot resolve this issue. Thanks in advance -bda- Tag: DataGrid cell double click event Tag: 78960

    - 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: DataGrid cell double click event 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: DataGrid cell double click event Tag: 78934

    - fileacces problems Hi, I'm in the middle of developing a c# project. When I run my application from VS.net it's run from the projects bin\debug library. My problem is, that when closing the application I am writing a xml file containing some settings to this library, but I get an "Access denied error". I am experiencing this error because the debug folder is marked as "read only". It doesn't matter if I uncheck the "read only" checkbox, because everytime my project is compiled, it is set again. How do I change this, and why is the acces to this folder restricted to "read only"? Thank you. Best regards Torben Tag: DataGrid cell double click event Tag: 78915

    - Autocomplete combobox For all of you who are searching for auto complete functionality in .net combobox. I wrote this code yesterday after being unable to find something usable and workable on the internet. All examples that I've tried either bulky and simply not elegant and inefficient or does not work properly. Maybe I was just not lucky and patient enough to try more examples :) instead I wrote my own code. Hope it helps someone. I appreciate all comments and bugs in the following code being posted back to the group. Regards, Michael Shapiro P.S. call this sub from KeyUp event of the combobox Public Sub AutoComplete(ByVal cbo As System.Windows.Forms.ComboBox, ByVal e As System.Windows.Forms.KeyEventArgs) Dim index As Integer Dim p As Integer Select Case e.KeyCode Case Keys.Back, Keys.Left, Keys.Right, Keys.Up, Keys.Down, Keys.Delete, Keys.Tab Return End Select p = cbo.SelectionStart index = cbo.FindString(cbo.Text.Substring(0, p)) If index = -1 Then Return cbo.SelectedIndex = index cbo.SelectionStart = p cbo.SelectionLength = cbo.Text.Length End Sub Tag: DataGrid cell double click event Tag: 78911

    - Form transparency issues Recently I wanted to create a small little program that could sit= on the desktop and not block the desktop wallpaper=2E There are= two methods to accomplish this ( that I am aware of )=2E 1) create a solid color bmp as a background image and set the= transparency key to match its color 2) specify the form's background color with a matching= transparency key Now my issues with both methods, but first it should be known= that I have set the forms to have no border or title bar and= have implemented code that allows me to click-and-hold anywhere= ( with exceptions listed below ) on the form and move it=2E The= data actually displayed on the form is just text and one= rectangle, all drawn by me ( there are no controls on the form= itself )=2E 1) I have two issues with this method, although it is what I'm= prefering to use at the moment=2E The first seems to be the= discrepancy between how the program is handled when the= computer's Color Depth is 32bit or when it is less than 32bit (= 16bit )=2E When the color depth is 32bit then I am able to click= on the entire area the form inhabits ( even that which is= transparent ) and move it, but if the color depth is less than= 32bit ( 16bit ) then only the drawn text or rectangle outline (= since it has no fill ) can be clicked to drag the program= around=2E Clicking on the transparent areas just passes the click= through the form to whatever is below ( even when I know the= form has focus )=2E I'd like to be able, regardless of the= desktop's color depth, to click anywhere within the form area= and move the application=2E The second issue I have with this method occurs when I take my= executable and put it on another PC ( my PC is XP Pro, the other= PC is XP Home=2E=2E Both SP2 )=2E The problem is similar, but a= little different=2E When the 2nd PC's color depth is at 32bit,= the transparency does not work=2E The green/lime ( that's the= transparent color I'm using ) background shows=2E Needless to say= this is not acceptable=2E When I change the color depth to less= than 32bit ( 24bit this time ), the transparency actually works,= but I come across the same issue of clicks on the transparent= areas just passing through=2E 2) With this method I have not tried it on a 2nd PC yet ( I don't= have it available where I am atm )=2E Its basically the same= "issue" as mentioned above with color depth less than 32bit,= except it does it with a color depth of 32bit and 16bit=2E Clicks= on the transparent areas just pass right through=2E I'm tempted= to just go with this method and possibly make one area on the= form that is meant to be used to drag it around ( similar to the= idea of the box that appears to move tables in MS Word ), but= I'm hoping there's a solution I'm unaware of before I do that=2E Anyways, all of this brings up some interesting questions=2E -What does color depth have to do with transparency handling? -Does the version of XP ( Home or Pro ) handle transparency= differently?

    - Odd closing problem I have a base form with a Cancel button (btnCancel) and a simple msgbox routine. I would like to have a routine closing check to prevent loss of data. Dim i As Integer i = MsgBox("Exit?", MsgBoxStyle.YesNo + MsgBoxStyle.Question) If i = MsgBoxResult.Yes Then Me.DialogResult = DialogResult.Abort Me.Dispose() End If I have another form that inherits from the base form. In both parent and decendent the Cancel button property of the form is set to (None). The problem is this. Even given the above, even given that I've traced the code and can see that the Me.dispose call is NOT being made when I click No, the form still closes.

So I bind it Organizations to the listbox control. lstSelectedOrgs.DataSource = null; lstSelectedOrgs.ValueMember = "OrganizationID"; lstSelectedOrgs.DisplayMember = "OrganizationName"; lstSelectedOrgs.DataSource = Organizations; I initially populate the control. Then I have a way to remove an item. And then I bind it again. At some point, all of a sudden, what shows up in the list box looks like this.

    - Beta Readers Wanted - Whidbey C# - (O'Reilly Author) This is a one time request for beta-readers for a new book I'm working on. ************* I'm writing a new book on Visual C# 2.0 - target audience is C# 1.x programmers looking to move up to 2.0 (code-name Whidbey). The ideal candidates have been programming in Visual C# 1.x for a while, are familiar with and comfortable with all the language fundamentals, delegates, creating windows and web applications and so forth and are ready to learn what is new in Visual Studio and C# 2.0, as well as highlights of what is new in creating Windows and Web Applications. I will post the chapters after I've written them but before they've been edited or tech-reviewed. Your job will be to provide guidance and advice as to how helpful the chapter is, what is missing, what could be clearer, etc. You can expect to read (and respond to) about 40-50 pages per week through Thanksgiving; starting next week. Ideally, you'll have the Visual Studio 2.0 Beta installed on a computer and will be able to try the exercises, though this is not strictly required. There is no financial compensation (though active participants will receive a copy of the book when it is published, and an acknowledgement in the book itself). You will need to sign a Non-disclosure agreement and you'll need to join a forum on Delphi (membership is free). If you are interested, please send me email (jliberty@LibertyAssociates.com) with your name, email, C# experience, etc. Thank you.

So lets say the control has a height of 300 pixels and the scrollable height is 1000 pixels then I'd like to be able to just make pixel 500 appear in the top left of the controls visible area. If this isn't possible what alternatives are there for scrolling a user control programatically. Many thanks in advance for any answers. Best Regards, Steve.

    - Client side controls in IE not working as expected I am developing a windows forms user control that will be hosted within IE from a web page. For testing purposes and on the client machine, I changed the .NET Framework security policy to give full access for the site that has the control. After all this, IE shows the control fine without problems. The problem happens when the control is signed with public private keys pair, IE doesn't show the control but shows an empty box instead (like an image link is missing or something).. This is the HTML code i am using to host the control: <OBJECT id="HelloWorldControl1" height="500" width="500" classid="NetAppletCtrl.dll#NetAppletCtrl.HelloWorldControl" VIEWASTEXT> </OBJECT> Any comments why IE doens't show the control when it's signed. Do I have to specify the strong name? I tried a lot and couldn't figure out how.. Maybe it's a bug in IE!! Thanks, Tag: DataGrid cell double click event Tag: 78851

    - mshtml and windows services 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: DataGrid cell double click event Tag: 78849

    - ImageLists on localized forms Hi. When setting Form.Localizable = True in Visual Studio, any ImageList on the form is copied/serialized into the resources for each language. This behavior is really annoying, since I only want to have _one_ copy of the icons (the same icons for all languages). Right now I have to either manually update the icons for each language or remove the serialized ImageList from the resx files. Another problem is that the application is getting "bloated" because of the multiple copies of the same icons. Is there any way to avoid this behavior? I already have implemented a customized LocalizationFilter ( http://windowsforms.net/articles/localizationfilter.aspx ), but the Windows Forms designer seems to ignore it when checking if the ImageLists should be serialized.

Using the images itself is not a problem, but when I run my application it becomes really slow and my CPU usage goes up to 100% for a time... Is there a better way of setting background images? It's just 3 images I think, all pretty small, and I already created the objects for the images and set them to the controls at runtime so that it uses only 3 objects and not new instances for every control. But still... It can't be that hard just to show a couple of images...? Many thanks for your help... Andreas Tag: DataGrid cell double click event Tag: 78810

    - Richtext SelectedText Selectionstart I have a very ODD situation. I have a RichTextBox and a button. In the button click event I have the following: me.richtextbox1.SelectedText="test" Assuming I start with "aaaabbbbcccc" in the richtext box and I place the caret between the a and b and hit the button. I get "aaaatestbbbbcccc" as expected. Then I click between the b and the c and hit the button I get: "testaaaatestbbbbcccc". I added some watches on richtextbox1.SelectionStart and find that the first time it is 5 as expected. But on the second button press it is zero! Also the SelectionLength is zero on the second press even if I set the cursor between the b and c and drag across the first three of the c's. This all occurs in my actual application, so I created a simple form with only these two elements and it works fine. So obviously something else is interfering with this operation in my real application. I am at a loss as to what! In the real app the richtextbox is bound to a dataset, but I can't see why that should cause this behavior. I don't see any other events firing that might somehow screw up the SelectionStart like this. The Richtextbox is on a tabpage (and so is the button), but again I see no reason why that should have an effect. Anybody else ever struggle with this?

    - simple binding of controls to object properties - refresh controls I have a dialog with controls bound to class properties, e.g. : numericUpDownPort.DataBindings.Add("Value", localOptions, "Port"); textBoxDatabaseName.DataBindings.Add("Text", localOptions, "DatabaseName"); textBoxDataUsername.DataBindings.Add("Text", localOptions, "DataUsername"); - i.e. localOptions (a member of the form) is a instance of a class with properties DatabaseName, Port etc. My problem is that when the underlying object is refreshed (user can load the class from a file), the controls don't update. The object's properties are now different from the user interface. How to I force the controls to reload their data from the object? I thought Push/PullData() might be my new friends but these are protected methods. Thanks for the help, Rua HM.

    - ComboBoxes and the sorted property Discovered a fun one that I thought I should share, and hopefully catch Microsoft's attention to update some documentation. I'm a bit new to VB.NET, and was struggling with getting a combo box to work. I was attempting to take advantage of the cool way to load a combo box via a datasource, rather than the old VB6 way of adding selections. First I tried an array of objects. I had some issues with that that I suspect had a lot to do with not overloading ToString on the class so the combo box would return the right thing for the displaymember item. But I had also read some bugs around arrays and combo boxes, so I switched to a disconnected dataset. I had a heck of a time getting the combo box to load properly. I kept getting either no data in the combo box, or it kept showing the phrase "System.Data.DataRowView". I found out that you have to set the datasource property first, before you set the datamember and the valuemember properties. But the real kicker was that you can't use the datasource and get it to work if the sorted property on the combo box is set to true. It appears that if you set that property to true, then the combo box assumes you're going to do things the old VB6 way and use the Add items method to the combo box. My tipoff something was wrong that I'd watch the debugger, and right after the statement like this: cbTest.DataSource = dsInfo.Tables(0) the value of cbTest.Datasource was "nothing", like the assignment didnt take. In order to get things to work the way I wanted them to, I simply built a dataview that sorted the table for me, and fed that to the combobox with the sorted value off, and it finally worked. Three weeks later, of course. Would someone from Microsoft confirm that you shouldn't use datasource in combo and list boxes if you set the Sorted property to true in the form designer? If that is the case, note that somewhere in the MSDN information about the ListBox and the ComboBox classes!! It's not mentioned in the MSPress books either (I have Programming Microsoft Visual Basic.Net, the 2003 version, ISBN 0-7356-2059-8) Tag: DataGrid cell double click event Tag: 78798

    - Accessing Files via HttpWebRequest from Virtual Directory in IIS 6 I have a virtual directory setup in my web service. ...47.169/webservice1/myvirtual/table1/image/ I can browse to my image directory and see the 100 or so compressed binary image files that reside there. The problem is that nothing I do will allow me to access the individual files that reside in the image directory. I keep getting The page cannot be found The page you are looking for might have been removed, had it name changed or is temporarily unavailable. That is what I get when I just double click on one of my files. when I try to access via a webrequest from my client application, I get a 404 error.

    - Strangeness in OnPaint Hi, In windows forms (vb.net), i use my own controls subclassed from base controls and i override the Onxxx methods. for example: Public Class MyBouton Inherits System.Windows.Forms.Button . Protected Overrides Sub OnPaint(ByVal pe As System.Windows.Forms.PaintEventArgs) MyBase.OnPaint(pe) . Protected Overrides Sub OnClick(ByVal e As System.EventArgs) Mybase.OnClick(e) . I saw that : - for some controls (ex: combobox), i can't access to OnPaint but i can access to OnClick .. - for these controls, if i had in the constructor : Me.SetStyle(ControlStyles.UserPaint, true) i can now access to OnPaint (then i must draw the control even if i put MyBase.OnPaint(pe)) but if i put : Me.SetStyle(ControlStyles.UserPaint, false) i can't access to none Onxxx - in some controls (ex: Button) without Me.SetStyle, it is ok, i can access to OnPaint I saw also if i intercept a windows message, it is ok : Protected Overrides Sub WndProc(ByRef m As Message) MyBase.WndProc(m) Select Case m.Msg Case &HF ' =15 =Paint Can anybody explain this strangeness ? Is it a known bug ? Is it better to use always windows message instead of OnPaint ? Thanks for advice.

    - Event log is full I have an app that catches errors with Try Catch blocks as follows: Catch ex As Exception Dim Event1 As New EventLog Event1.Log = "Application" Event1.Source = "QuickCheck" Event1.WriteEntry("Error in PlayBalance_EnterEvent. Message is: " & Chr(13) & ex.ToString) End Try In doing so, when the event log gets full, I get an unhandled exception stating the event log is full. It seems I need a global try catch to handle this. Can this be done? Is this the best way to handle?

    - tabPage.Focus() doesn't work? Hi, I have a TabControl in a WinForm witn two tabs. At some point I want to switch focus from the first TabPage to the second TabPage. The documentation says that any control (which seems to be the case for the TabControl) that derives from Panel aren't selectable. Since I think this is a simple wish I can't imagine that there shouldn't be a workaround for that. Do you have helping ideas? Thank you very much.

    - ShowDialog() problems In efforts to upgrade dev environment to VS.Net 2003 w/FW 1.1, I have done the following: On a new computer (leaving old environment alone): -Installed the SourceSafe Client (with NetSetup) -Set a label across all objects in the archive marking where dev environment is being upgraged -Installed VS.Net 2003 to include Pre-reqs, IDE, MSDN library. -installed VS.Net 2003 hotfix (836454) fo "updates" can be retrieved from the web - using VSS, retrieved latest version of all files to working folder - opened main solution Upon opening the solution, VS.Net 2003 had to convert all projects, it was done without errors being reported... -Installed ODBC.Net Managed provider (for compiling) -Installed previously used 3rdParty component for compiling (DevPower Solutions FTP for .Net) -Compile without error On run, both from the IDE (debug), and from outside the IDE (debug and release) my ShowDialog() for the usr/pwd prompting seems to be MODELESS ??? App does the following: -Main entry point calls App.Run(new MainForm()) -MainFrom gets created -MainForm_Load() event handler creates a new LoginForm(), and does a form.ShowDialog() ...note, LoginForm:BaseForm, BaseForm:Windows.System.Forms.Form) At this point, I see a "flicker" for the login form, but does not hold up waiting for me to enter data/press OK button, etc... The LoginForm_Load() handler sets the DialogResult to CANCEL, so the switch/case processing the DialogResult after the call to ShowDialog() promptly ends. I have a call to tech support on this....pending resolution...anyone have thoughts on this???? Thanks in advance.
