    - Get rows as shown on DataGrid (WYSIWYG) Hi, How do I get DataGrid to return all the rows that are currently displayed on the screeen as seen by the user (WYSIWYG). The main requirement is the users can scroll up-or-down the grid, and refresh (retrieve the latest data from the database) the rows as seen by them by clicking a "Refresh Shown Rows" button. However they do not want to select any particular row (therefore I am unable to use any of the "Selected" functions). The DataGrid is binded to a DataView, which in turn is binded to a DataSet. The DataGird has a fixed height, showing 12 rows at any time. Therefore at any point of time I just need to refresh the 12 rows as seen by the user. Pls kindly advise. TQ.

    - Interfaces with vb2005 project Hi, I am developing a windows project. In one of my form I have few procedures and functions. Everything is working great. Now I am told to do it through interfaces, means create a interface class and then implement it. I am little concern doing it. 1. Do we really have to create a interface when we have to implement it ONLY in one class nowhere else. 2. Are there any performance issues when we are using interfaces methods instead of method with not interfaces implement. Also I want to know when is the right time to use Interfaces.

    - VSTO modal form question Hello I'm working on a Microsoft Word VSTO (Visual Studio Tools for Office) project (2003). The 'host' Word document has a custom command button which brings up a Windows Form via the following (C#) code private void RunScript_Click( Office.CommandBarButton Ctrl, ref Boolean CancelDefault ) { __pyScriptForm = new PyScriptForm( this.ThisApplication ); __pyScriptForm.Show(); } where 'ThisApplication' is of type /Microsoft.Office.Interop.Word.Application/. This form is used to run scripts written in Python, capture their 'StdOut', and write it to the underlying document. This works as I want - as the script runs, the output appears on the document below. However, I think it would be preferable if the form were shown modally - the document shouldn't be accessible while a script is running, and there's a Cancel button on the form that will stop the script. But if I do this ( with ShowDialog rather than Show ), then the written output doesn't show up until the Form is closed. It's more satisfactory if you get the data appearing right away. Can I have my cake and eat it with this - ie. have a modal form, but also see the script output? TIA G.F. Tag: any one who knows some website about the socket with cshap.net ? Tag: 93289

    - Windows Form Designer Formatting I use the designer in Visual Studio .NET 2003, and I really don't like the way it automatically generates some things. For example, I don't like the extra bloat of everything having System.Windows.Forms when it's alread imported. I know there are situations where it can cause naming collision, but those don't apply here and I want to do away with the qualified namespace name. Any thoughts?

    - SplitContainer Question I dropped a split container onto a form, it's vertical and I can see the splitter bar OK and move it left to right. Then I dropped another split container in the right panel (panels2) of the first splitcontainer set it to horizontal. When running the app the application splitter bar of container2 in Panel2 of Container 1 is not visible.I can drop controls on the two panels of container2, but I can't resize the panels of panel 2 because the separtion line between the two doesn't show when running the program.

    - DrawString calls inconsistant in Paint Handler! Hi, I am using Graphics.DrawString in the paint handler of a label. The text comes up and behaves as expected on all events such as resize of the lable control. The problem is when i move a messagebox/ another application( say notepad ) across the lable. In this case a clean repaint of the text fails to appear. The text gets drawn erratically or altogether disappears. What could i be missing out on in this code. I tried inheriting from System.Windows.Forms.Label and overriding the onpaint method with same results. I had also tried having the usercontrol as UserControlStyles.UserPaint. I was trying to avoid having to create the Graphics object for the lable in the main form as this is not advisable; but i tried that also with even worse results. Any help to get me have the paint handler working properly would be greatly appreciated. Regards, //code snippet private void lblMessage_Paint(object sender, PaintEventArgs e) { if( lblMessage.Text != "" ) lblMessage.Text = ""; Graphics g = e.Graphics;// Graphics.FromHwnd( this.Handle ); //g.SmoothingMode = SmoothingMode.AntiAlias; StringFormat sf = new StringFormat(); sf.Trimming = StringTrimming.EllipsisCharacter; sf.Alignment = StringAlignment.Center; sf.LineAlignment = StringAlignment.Center; sf.FormatFlags = StringFormatFlags.LineLimit | StringFormatFlags.FitBlackBox | StringFormatFlags.NoClip ; g.DrawString ( strText, this.Font, Brushes.Black, new RectangleF( g.VisibleClipBounds.Location, g.VisibleClipBounds.Size), sf ); } Tag: any one who knows some website about the socket with cshap.net ?

    - Multithreaded Panel Visiblility Hi everyone, I've got myself a C# .NET 1.1 application I'm making where a docked Panel that contains some progress bars etc. is being toggled between Visible and not. Basically a user drags some photos into the window and it activates a background thread that shows the panel, does some work, and hides it again. If this is not in a separate thread, it works! I've tried doing a manual Update(), and PerformLayout() calls, but nothing works. The thread work happens, but the panel never shows. I've also tried Application.DoEvents(). private void itemImages_DragDrop(object sender, System.Windows.Forms.DragEventArgs e) { ArrayList formats = new ArrayList(e.Data.GetFormats()); if(formats.Contains(DataFormats.FileDrop)){ //imageImportFiles = (string[])e.Data.GetData(DataFormats.FileDrop); imageImportFiles.Clear(); imageImportFiles.AddRange((string[])e.Data.GetData(DataFormats.FileDrop)); imageImportThread = new Thread(new ThreadStart(this.importImages)); imageImportThread.Start(); } } private void importImages(){ imageImportPanel.Visible = true; imageLoadProgress.Maximum = imageImportFiles.Count; imageLoadProgress.Value = 0; ArrayList imageFiles = new ArrayList(); foreach(string filePath in imageImportFiles){ importDirectory(filePath, imageFiles); } imageLoadProgress.Maximum = imageFiles.Count; imageLoadProgress.Value = 0; foreach(string filePath in imageFiles){ string label = getFileName(filePath); Image img; int imgId; ListViewItem item; imageImportStatus.Text = String.Format("Importing {0}...

    - Dragging icons in a ListView Hi, I still cannot believe there isn't a standard property (or set of properties) that would allow me to drag, move and rearrange icons in a standard ListView .net control! I was trying different combinations of properties (like AutoArrange = False, and many others...), but it looks like it does not work unless you handle some of the events (OnBeginDrag etc...). It would seem natural to think that such a basic functionality would be provided via standard property, but so far I have not found a way... Does anyone know a way to do this by settings without having to write code? Thanks, Ivan Tag: any one who knows some website about the socket with cshap.net ? Tag: 93266

    - MDI form question. I have a MDI container form that l load client forms into. When I set the FormBorderStyle to None before calling show on the client form, I can resize the container form and if there are unseen areas of the child, it shows the horizontal and vertical scrollbars (that's fine). However, I want the FormBorderStyle set to Sizable so that I can treat them like Excel workbooks and minimize, maximize, and move around however I want. So I set FormBorderStyle to Sizable and the child's windowstate is set to maximized. The PROBLEM is that when the container form is sized to a smaller size so that the child form has unseen areas, there are no scrollbars and you cannot get to those unseen areas of the child without restoring down the child. That is similar to Excel, except in Excel when the workbook is maximized and the container is smaller than the workbook, there are scrollbars available so that you can get to the unseen areas of the child. How can I duplicate how Excel handles this? Tag: any one who knows some website about the socket with cshap.net ? Tag: 93264

    - Freezing datagrid columns I'd like to set up a datagrid so that, when the user scrolls right, the first column (I'm only after one column at the moment, a method that coped with multiple columns would be nice) remains where it is. i.e. similar to the freeze panes command in Excel. I've seen that lots of people have posted this question in the past, but I haven't seen an answer. I've tried Ken Tucker's ColoredGridColumn class but it doesn't work for me. I've seen the idea of using two datagrids side by side but can't figure out what I'd need to do to override the events of the vertical scroll bar on the right hand grid so that it automatically applied to the left as well. At the moment, my thought is just to completely remove the scroll bars and replace with left and right buttons where 'right' will just remove from the column style collection, and 'left' will add back in, but that is obviously a non-standard UI so I'd rather not do it that way. Anyone have any details of a good way to do this? Tag: any one who knows some website about the socket with cshap.net ? Tag: 93258

    - Tab Control and Combo Box (bound) I have a combo box that is on a tab page in the tab control. The combo box is bound to a dataset - I already know about the problem of having to set the selected index twice to set it at -1. At runtime, when I go to another tab page, the selected index is still at -1, but when I go back to the first tab page where the combo box is, the selected index of the combo box is set back to 0, and there is text in the combo box.

    - OnPaintBackground vs. Scrollbar Hi, I have a user painted backgrounf form. When form has got a scrollbar I run into trouble with drawing. I get the ClipRectangle in the EventArgs. It is depends on the graphics face, not the virtual (I mean that if I have a from with 400px of height and have a control at 600px and I scroll to the control I will get a ClipRectangle with Y like 25px, not 575px with 200px height). Even I cannot ask the virtual clientsize of the form, only the displayable face through Form.ClientSize. There is a PrefferedSize property, but it gives the form.Height value, not the ClientHeight... So I have determine the "border" of the form... But even complicated with scrollbar... So the real question is: Do I miss something or missunderstood with OnBackground paint + ClipRectangle + Scrollbar.Value and Scrollbar.Maximum (which does NOT gives the PrefferedSize.Height if it is the VScrolllbar.Maximum property)? Or what is the nice solution to handle the scrollbar value and draws the exact face of the background (if the face of the background as big as the virtual size of the form)?

    - Add satellite assemblies to a signed assembly??? Hi all! Is it possible to add a satellite assembly containing resources with localized strings to an existing assembly that has been signed with a unknown private key? My problem: I have a third party product with Windows Forms controls that uses resource files. There are however no resource file for Swedish included. So would it be possible to create a resource file with the Swedish translation, compile it to a satellite assembly and have the third party assembly (that is signed with an unknown private key) use my new resource file? (Note: I'm not interested in sending my translations to the third party manufacturer and ask him to sign my satellite assembly) Maybe it is impossible for security reasons??? Or could there be some nice solution to this problem? Question 2: Lets say that I'm about to create a WindowsForm gui controller that I would like to distribute in a signed assembly. Then I would like the users to be able to create their own recourse-files (with their own translations). What must I do to accomplish this?

    - Plugin Architecture Question - Best Practice For Forms Update Plugin Architecture Question - Best Practice For Forms Update I have an application that follows a simple plugin architecture. Yes, it is my first plugin app, so please bear with me. There is an interface defined, and followed by the host exe and plugin (or client) dll. The plugins reach out into the world and get bits of information (stock prices, new mail, disk space, rss feeds... whatever) these bits of information end up as treenodes in a treeview in the host app. My question is: When a plugin is ready to deliver updated content, say perhaps by use of a timer, what is the preferred way of notifying the host app? (assuming that my plugin will be in a seperate thread) Should I pass a reference to the form? Do I raise an event? I know that you should operate on winforms in the originating thread only , so they don't play well with refreshes sent from timer threads (or any other thread). I am able to use invoke to get around a few things, but I was hoping to find a simpler solution, and wanted to hear some opinions.

I have a standard list box (System.Windows.Form.ListBox) on a form and I'm trying to trap for activity on the SelectedIndexChanged event.

    - Copy/Paste of a Winform in VS 2005 Hi there, I select a Winform (.cs file) on the Solution Explorer and right-click "Copy", then I paste the WinForm on the same project. I rename the new .cs file and then I rename the Winform object itself using the designer's properties side bar. The problem is that VS 2005 also renames the original Winform object in the original .cs file, wreaking havoc the next time I compile. Â¿Any ideas to avoid this? Any help is appreciated.

    - Control Width and Height limited to 32,767 pixels Why are controls limited to 32,767 pixels? The width and Height properties are supposed to be 32-bit integers. I am trying to make a timeline control that could be scalled out to a unit increment of 0.01 seconds per grid division (each grid division is 50 pixels) and have a total timeline of 10 minutes. This means my Control must be able to be at least 3,000,000 pixels wide. Whats strange is that the controls were sizing properly earlier today, but all of a sudden, for some reason I can't explain, this limitation has suddenly been introduced. Can somebody please help me understand this!? I have done some browsing around, and I saw that it was a reported bug on some websites ie: Item #20 on these websites http://www.jelovic.com/dotnetbugs/ I'm not sure if this is considered a bug by Microsoft - I can't find any mention about it anywhere else. Is there a way (preprocessor directive, or optimization setting) to force the compiler to use 32-bit integers for these fields? I really don't understand why it WAS working earlier if this is a "built-in" limitation of Control.Width and Control.Height. Just as background, my timeline controls are extending UserControl. When the user scales (zooms) in to the control, I specify the size of the control to be: Timeline.Width = MAXIMUM_TIME * ( GRID_INCREMENT / ( scale * 100.0f ) ) ; where MAXIMUM_TIME is the maximum length of the timeline in centiseconds, GRID_INCREMENT is the distance in pixels between units, and scale is the "zoom level" of the timeline - the lowest zoom level is 0.01. At the lowest zoom and a timeline of 10min, this would generate a width of 3,000,000 pixels. Any ideas on whats going on? Or how I can get around this?

    - Position of System Tray Icon Probably very easy question, apologies, newB to Winforms... I've successfully created a NotifyIcon to sit in the system tray.

    - Activating another process Hi, I have a windows forms application that is single instance. It checks its existance with a mutex and shows itself with the following lines of code if it is already running (using P/Invoke): AttachThreadInput(_hThread, hThread, 1); BringWindowToTop(hWnd); ShowWindow(hWnd, SW_RESTORE); SetForegroundWindow(hWnd); AttachThreadInput(_hThread, hThread, 0); On XP Systems the ForegroundLockTimeout is set to 0 to achieve this behaviour. Sometimes, when I launch the App from e.g. Windows explorer, the application does not get the focus correctly. It is shown in the taskbar as active, but the calling application (here windows explorer) still has the focus somehow. I need to explicitely klick into the app to activate it. This behaviour is not always. very strange. We also tried this with a Win32 Application and we can reproduce the behaviour there as well. So it has nothing to do with .NET Any solutions to this problem? Thanks in advance for ANY help Greetings Frank Stegerwald Tag: any one who knows some website about the socket with cshap.net ?

    - Does Registry Key exist, if not go to form.. in C# I need to detect if a key exists like this, HKEY_CURRENT_USER\Software\MyCompany\MyProgram\UserName If the key does exist, I am opening my main form; Application.Run(new frm_Main()); Else Show.Dialog of my User Setup form. The form launching I can handle without problem, my problem is seeing if the key exists, and if not, then doing the redirect. I just can't seem to get this to function properly, if the key isn't there I get a object error, if the key is there then the app loads the main form properly. All suggestions are greatly appreciated! -- D @ premierdata Tag: any one who knows some website about the socket with cshap.net ? Tag: 93187

    - MDI Menus ChildForm I have a MDI parent form. The form has a Infragistics toolbar as menu tool bar.. I have a child form which contains a User control. That User control holds a third party TE Control The TE Control's Menu Items are not displayed since that is part of user control Now when I open the child form which displays the TE Control I have to show the menu related to the TE Control.. when I try to place the menu of the TE Control to the child form I am not able see it coz this is an MDI.. When I want to merge with the parent I could not as this is not an Infragistics tool bar and at the same time I could not display this in the childform too which is an MDI behaviour. Please let me know any ideas of doing this.. Please note we cannot create a infragistics toolbar for TEControl menu bar the reason being the control is tied up with the menu handling items..

    - icons cannot be displayed anylonger Hello, I have bought a collection of professional icons in different sizes and formats like png, bmp, ico, gif. Now I have placed in one form the icons on navigation buttons within my form. I don't know what happens but whatever I do, the icon is not visible so I only see a gray button without any icon. If I enter a text for the button, the text will be displayed (that means the compiler is realy compiling). What else can be the reason that icons will not be visible? I tried both ways: one via image list + image index, another way via direct pointing to the icon file. Tag: any one who knows some website about the socket with cshap.net ? Tag: 93183

    - Different TreeView on different PCs Hi all, in my WinForm app I use a TreeView as left menu. In the last months I made several modification to the nodes (added, removed, renamed, etc, etc). When I install the app (using a VS.NET 2003 install project) on some PCs the most uptodate treevire is shown while on other there is an older version of the treeview (it displays nodes no more present in the projects!!). Any idea? Thanks in advance! Marco Tag: any one who knows some website about the socket with cshap.net ? Tag: 93168

    - A report VIEWER control ! How about the report DESIGNER control ? Hi all, our team is really excited about the new ReportViewer control. Heck, it even supports custom data sources, which fits in nicely with our overall application design. The only thing that seems to be missing then is a control that allows our users to design (or at least modify) reports themselves. In our mind, the biggest advantage to working with a report engine and report files is the ability to provide your users with customizable reports. Moreover, we know this functionality exists since we (programmers) use the report designer in VS2005. So it would be up to Microsoft to package it into a control and ship it. I'm sure somebody else has already asked about this by now but repeated google queries have turned up nothing relevant. Thanks for any light anyone can shed on this.

Did you already take a look at the documentation of the 'System.Net.Sockets'
namespace?
