    - Asychronous events and rendering contexts Hopefully this is the right newsgroup. I figured you guys would be the best experts on this. I am learning C# and .NET and went a little crazy with the events. Now I am not sure how to isolate this problem. Here is my architecture, I have: 1. an OpenGLPanel class derived from UserControl that handles the repainting using OpenGL. A render event is published for subscribers to paint into the window. 2. a Manipulator class that handles mouse and keyboard events to cause rotations, scales, etc. using events. 3. a Camera class that rotates, zooms, etc. based on any subscriptions to a Manipulator and posts view update events. Okay, simple scenario, I have a form with two OpenGLPanels, visible. Each has a camera and listens for the camera events. The camera listen for the manipulator events. The manipulator listen's for the form's mouse and keyboard events (a complete cycle!!!!!). The main form has a method to draw an object and subscribes to the OpenGLPanel's render event. Things work great in a serial world. I even could attach a manipulator to both cameras, etc. Pretty cool!! I was just started to really like this new environment. I decided to switch from just firing the event to doing an asynchronous call (as a first step to remoting the camera). I would really like a OneWay approach for the camera, but both of these destroy the OpenGL context or something. Right now, I am only processing the camera updates to the OpenGLPanel's asynchronously, but would suspect that all of the mouse events are also handles asynchronously. The render events will always be sequential, but I would also like to have the manipulator events happen OneWay to the cameras. The problem with the render made sense to me at first, if I set the active rendering context and then the thread got bumped, etc. I added [Synchronization] in front of the OpenGLPanel class. It and the Form1 class are the only ones that make OpenGL calls. I get one of the Panels not redrawing. The calls are all happening, but I think something in the state got messed up. The other panel starts off blank and then when I force a particular event (set of events) it shows up and works properly. Changing the subscription order seems to reverse which panel works and which one does not. Pretty much every method is atomic and nothing is left in a bad state (if I programmed it correctly). I decided to add [Synchronization] before all of my classes, but nothing helps. BTW, I never create any threads, just those (two) from a default Windows form. I am running on a single CPU machine. Okay, now for the question(s): 1) Is this a correct way to protect a shared system resource? 2) Is there a better way? 3) Any guesses on what might be going on before I attempt to boil the code down to a simpler test case (or assugn it as a midterm question :-) )? 4) I can see the High priority thread preempting the other thread, such that mouse calls are continually triggered before any updates to the display can finish. I would expect, that after I release the mouse and wait idle for awhile the display would redraw. Some other questions on multi-tasking: 4) My counter indicates I am still getting 70-90 frames-per-second, but visually, it is more like 1-2 fps. 5) Are the events queued, or do I always just get the most recent event? If they are queued, is there an easy way to only get the latest. I want to display with the latest camera, not march thru all of the events. 6) How does a Windows form split up its tasks into threads? I know you want the user interface thread to be at a high priority, is everything in the form then issued at a low priority? This would include control updates and displays, so ... This is all educational code for my own amusement, so I happy to give the entire project to anyone interested in looking into this further.

    - Good Practice on ListBox Greetings I want to display a listbox on the form which will include two columns from the data table" FirstName" & "LastName" What I've done now, is modify the DataAdapter to include two additional colums as: [FirstName] + " " +[LastName] As NameFN [LastName] + " " +[FirstName] AS NameLN I've selected NameFN as the DisplayMember of the listbox However, I've also selected the Sort option to be true So what I see on the listbox doesn't correspond to the record selected on the form. The record is selected automatically on the form because my DataSource Property is bound to the dataset object. Is this a good practice ? Or its better to create a dynamic Array List on loadup and use that ? If that is the case how can I make the list selection, make the record on the form change ?

    - Problem positioning controls within a panel with autoscroll=true I don't know if this is a bug or if I am doing something wrong, but hopefully somebody could help me. I have a panel with autoscroll=true, and I am trying to position controls within it, however they don't position correctly. According to MS's documentation Panel.Left "Gets or sets the distance, in pixels, between the left edge of the control and the left edge of its container's client area." Here's the sample code for you to reconstruct it real quick. Essentially its a form with a panel with autoscroll=true, a textbox of any size outside of the panel, and a button with the following click event handler. int x = 0; int y = 0; private void button1_Click(object sender, System.EventArgs e) { TextBox f = new TextBox(); f.Size = textBox1.Size; f.Multiline = true; panel1.Controls.Add(f); f.Left = x1; f.Top = y1; //f.Location = new Point(x1, y1); x1 += 100; y1 += 100; panel1.Refresh(); } It should draw textboxes diagonally toward the right, with a scrollbar eventually appearing. However, if you move the horiz/vert. scrollbars any bit after creating a few of these diagonal boxes, it jumps a huge gap, then creates the textbox. What I think should be happening is that it should create a lot of textboxes diagonally with no gaps between them regardless of whether or not the scrollbars have been moved at all. I have tried using the commented out location line above and I have tried setting the positions before adding it into the panel. Nothing has worked for me so far.

Does it create a lot performance and memory issues? Is it better to use the Hide method instead?

    - Problem/Bug: poor C# windows forms accessibility for disabled? Hi, Because the blind are unable to use a mouse, keyboard navigation is key. A major difficulty is that not all windows forms controls are keyboard 'tab-able' or 'arrow-able' or have "tab order". The application is built and the next step is to create the custom JAWS (Freedom Scientific)screen reader script to read the application. The application uses the accessibility properties for controls provided by C#. JAWS reads properties these fine --using a mouse for access. For example, JAWS can read ComboBoxes and DateTimePickers that are placed into DataGrid cells without any problem. The problem is the lack of keyboard access. Using Microsoft's accessibility SDK 2.0 tools: AccExplorer32, Inspect32, AccEvent32, I can gather a great deal of information. It appears that C# controls can not be given individual unique IDs. JAWS can navigate to IDs. Is there something that can act like a unique identifier? Different classes/objects are simply labeled WindowsForms10.Window.8.app3. This is too ambiguous. JAWS has a limited number of recognized classes it understands, but a substitution could be made if an unknown class was unique. What about custom controls? Is there a way to uniquely ID C# custom controls? There are many very interesting controls being developed in the .NET world, that could be read if there where more identifiers. Looking for help at MSDN and the Knowledge Base it seems that there is a significant difference between C# and C/C++ functionality in this context. How can I have keyboard access to my C# windows forms application? Can anyone offer any tips, or code samples?

    - Embedded Control in IE, control loads but get System.Security.Permissions.SecurityPermission request error in IE... Hello, I have been posting lately on my embbeded control. I have made some progress. My control is strong names, with allow partially trusted callers attribute. I have created a custom code group with full trust for my assembly. Before, my control would not load at all due to security issues. I would get exceptions outputed into my IEDebug log. Now i get no errors in my IEDebug log but in Internet Explorer (Exclamation mark at the bottom left of IE), I get an error: Request for the permission of type System.Security.Permissions.SecurityPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed.

As you can see, the first screen is maximized with the control buttons (minimize, maximize, close window) but the title bar, of the window, is not showing blue, as Windows standard, itÂ´s showing a part of a background image, giving to the user the sensation that it has no form title.

    - Creating a dynamic grid Hello, I have a question about creating a dynamic grid layout. The grid should have the following: - a rowheader(12 columns). (0) - a detail row with also 12 columns (contains the data). (1) - a second row with 3 columns where the first column is empty, the second column has a description in it like the rowheader above and a third column with the value of this row. (2) - a third row which has the same layout as the second row. (3) row (1), (2) and (3) should be created multiple times depending on the data. Is this possible to create this within C#. At the moment I draw this "grid" with seperate labels. I do this when I retrive the data for it. The data can change when clicking an other row in a different grid. My "label-grid" works fine but it is to slow when redrawing it when selecting other data because the labels must be removed from the form and created again within the code. I have also a screenprint how it must look but can not attach this. Thanks Tag: How to get embedded resources from any namespace in project? Tag: 83163

How to I, from a form (more precisly a base form) trigger the validation of the form itself. I want to ensure that the Validation events is triggered and all values transferred (trough databinding) before I peform a Save operation, however, calling the Validate() method does not cause the validation events to be triggered on the form itself. But it does case all data to be transferred for the controls on the form. Regards, TEK Tag: How to get embedded resources from any namespace in project? Tag: 83162

    - Hiding non-databound hyperlinks in a DataGrid I am brand new to ASP.NET and am now required to take over maintenance of a .NET/C# web application. On one of the pages I'm working on there is a DataGrid which has multiple columns. One of the columns is not databound and instead has up to three hyperlinks in it (Edit, Award, and Cancel). A couple of the hyperlinks should not be shown in certain cases. Now, mind you, I don't know if it's being done in the way that's best to do it. It looks like there is a "panel" being created to contain the hyperlinks that may not be visible. I don't know why though (i.e. why not just set hyperlink's Visible property and be done with it without a panel?). That being said, I want to change the page so that one of the hyperlinks does not show (i.e. Visible = False) based on a certain value for a session cookie. It's the Award link in the code shown below from the .aspx file in question. --- CODE BEGINS --- <asp:TemplateColumn HeaderText="Actions"> <ItemStyle HorizontalAlign="Center"></ItemStyle> <ItemTemplate> <asp:HyperLink id="hlEdit" runat="server" NavigateUrl='<%# "Edit.aspx?id=" + DataBinder.Eval(Container, "DataItem.PersonID") %>' CssClass="link-text">  Edit </asp:HyperLink> <asp:Panel ID="Panel1" Runat="server" Visible='<%# Convert.ToBoolean(Convert.ToInt32(Request.Cookies["core"]["sl"]) <= 9)%>'> <asp:HyperLink id=hlBids runat="server" Visible='<%# Convert.ToBoolean(Convert.ToInt32(Request.Cookies["core"]["sl"]) <= 9)%>' NavigateUrl='<%# "Award.aspx?id=" + DataBinder.Eval(Container, "DataItem.PersonID") %>' CssClass="link-text"> Award </asp:HyperLink> </asp:Panel> <asp:Panel ID="panAction" Runat="server" Visible='<%# Convert.ToBoolean(DataBinder.Eval(Container, "DataItem.PersonStatusCancel"))%>'> <asp:HyperLink id="hlCancel" runat="server" NavigateUrl='<%# "Cancel.aspx?id=" + DataBinder.Eval(Container, "DataItem.PersonID") + "&op=cancel" %>' Visible='<%# Convert.ToBoolean(DataBinder.Eval(Container, "DataItem.PersonStatusCancel"))%>' CssClass="link-text" > Cancel </asp:HyperLink> </asp:Panel> </ItemTemplate> </asp:TemplateColumn> --- CODE ENDS --- Now, the value of the cookie, when I bring up this page, is 1, which satisfies the condition...yet, the link still shows. I guess my question is two-part: 1) What is the best way to accomplish something like this? Do I have to use a DataList instead or can it be done using a DataGrid? 2) If this is best way to do it, then what's wrong with code above?

    - File.CreateText fails I am developing a Windows application. The source is stored on a network share, probably 6 directories deep. When I say: File.CreateText("G:\temp\" & _dataSourceInfo.Csv_filename) the file is created OK on the local disk G in directory temp. However, when I say: File.CreateText("%temp%\" & _dataSourceInfo.Csv_filename) it fails with a Directory not found, and is trying to create: \\networkShare\...\Application\bin\%temp%\CSV_Filename Why is this happening? Something to do with security? TIA Lars Tag: How to get embedded resources from any namespace in project? Tag: 83120

    - Validating of control data on Windows Forms My question is there any way to trigger controls validation from the code? I have a form where user can enter some query parameters and execute the query. Each control (TextBox, DateTimePicker etc.) has Validating, Validated handlers. If the user edits query parameters manually validation code is executed upon leaving control which is just edited. The application can also read default data from config file/command line. Such data is used to populate form controls upon form creation/loading but it does not trigger validation process. Is there any standard way to cause the Form to perform validation for all controls on the form? For all controls on particular panel? Tag: How to get embedded resources from any namespace in project?

    - Windows XP ComboBox bug when using "Windows Classic Style" I found a very odd bug while developing a Forms app with Visual Studio 2003. If you have a ComboBox with no items in it, when you click the arrow, an empty drop down list is displayed which is the height of 1 item. In Windows XP, this all works fine if you have your "Windows and Buttons" Display Setting to "Windows XP Style". However, if you change it to "Windows Classic Style", when you click the arrow in your combobox, it does not show the empty drop down list. Worse yet, the system "thinks" it is displayed so the UI is "locked" (just like when a drop down list is displayed) and your next click on the app will do nothing, because this is what would normally close the drop down list. A couple things to note: -If the combo box is not empty, it always properly displays the drop down list -It is not limited to .NET, I built a C++ app with Visual Studio 6.0 and get the same behavior -There are rare circumstances where it does work correctly in "Windows Classic View." Sometimes an empty combobox DOES display the empty drop down list, but it seems to be very rare. I can not explain why sometimes it does and sometimes it doesnt. I have not been able to come up with a scenario where I can consistanly get the empty drop down list to display in "Windows Classic View", in fact, I have only gotten it to happen a couple times. Here are the steps to reproduce (Must be running Windows XP): -Set your style to "Windows Classic Style" by right-clicking empty space on your desktop, select Properties, click the Appearance tab and select the "Windows Classic Style" in the "Windows and buttons" drop down list -Open Visual Studio and create a simple Windows App. Drag a ComboBox onto the Form. Press Ctrl + F5 to build and run the app. -You *should* see that when you click the arrow in the ComboBox, it does not display the drop down list. -Change your style to "Windows XP Style" -Now when you run the app you will see the drop down list DOES appear.

    - BUG: Nested groupbox in .NET 1.1 SP1 shows corrupted caption in themed Hello, .NET 1.1 SP1 contains a nasty bug (.NET 2.0 beta as well) which makes nested groupbox controls to show a corrupted caption text (in bold, which is chopped off) if the windows forms application is run on a themed XP system (i.e.: with windows themes turned on) and flatstyle is set to System (to enable visual styles). This affects all applications written for .NET and which use windows forms and nested groupbox controls, applications which used to work perfectly on .NET 1.1 but are now showing corrupted caption. See for a screenshot: http://weblogs.asp.net/fbouma/archive/2005/01/20/357210.aspx See for a repro case: http://weblogs.asp.net/fbouma/archive/2005/01/21/358006.aspx As the bug is pretty severe, and requires ISV's to change their applications to make them work on .NET 1.1 SP1 while there is nothing wrong with their code, I'd like to ask Microsoft to fix this a.s.a.p. I tried to contact PSS / online support but apparently I have to pay (!) for sending this information to MS, so I try to get your attention through the newsgroups. Please fix. Thanks.

    - Scrolling Problems in a Form Hi everybody, I have a little problem, no two. First my english is not quiet good so please try to understand what I want and help me, please ;) And second: I habe a Form. In this form is a ScrollableControl (modified, so it could raise scroll events), containing another Control painting an image. Okay, everything works fine, but if I deactivate the Form (it's a mdi child form) and activates another Form and than go back, the scrollbars are reseted to the default settings, very top and very left! I will get the same behavior, when I deactivate the hole application an than activate it again. If the mdi-child Forms are deactivate, there are showing the right scrollbar positions and the correct clipping of the image. Only when I activate the form, the form resets the scrollbarpositions :( Me first solution is, receiving the activate Event raised by the form and than set the scrollbar positions. This dosn't work! Than I try the receive all window messages to get the WM_ACTIVATE, WM_MDIACTIVE, WM_NCACTIVATE, WM_SETFOCUS and the WM_IME_SETCONTEXT messages. If I acted on these messages I got a really funny behavior of me application. I have deactive (by clicking to no application on taskbar) and than have activate (by clicking the taskbar icon), than the scrollbar shows again the wrong position, but when I moved the mouse of the form, the scrollbar reposition them self and show the correct positions. Now I react on every message posted throu the WNDPROC function and set the scrollbar positions. This works, BUT if I do a large/small de/in-crement scroll with one mouseclick the scrollbar do the de/increment and immediately set them back to the previous position. This isn't good :( Maybe some of you know the correct window message, so I can set me scrollbars I the form will activate by clicking the nonclient or client area, or the application and so on. Have many, many thanks Robert Groß Tag: How to get embedded resources from any namespace in project? Tag: 83082

    - Datagrid with colored columns pausing during setup I have a windows form that contains a datagrid with columns given coloured backgrounds via the DataGridColoredTextBoxColumn class. Data is loaded, and the table style set up, during the load event of the form. At present, the form half displays, then pauses, then completes. Is there any way of telling it to complete the set up _before_ displaying anything? Thanks. Tag: How to get embedded resources from any namespace in project? Tag: 83081

How can I load embedded resources from any namespace in my WinForm project?
For example, a namespace such as "MyApp.UI.Views"?

I have a Resources\Images\ folder in my main project containing embedded
resources. To load an icon from my main form using the "MyApp" namespace, I
use:

myIcon = new Icon(this, "Resources.Images.FolderClosed.ico");

Thanks in advance for any tips or suggestions,

-Ed
