    - Cached Configuration Data Hello, I have stored some new values in the .config file of my app. They were stored using a configuration object. If i read the value from the config object i can get the lastest values. But if i read the items using ConfigurationManager, i get old 1.1 behaviour, in that values appear to be cached. Any changes are not reflected until ap is restarted. Is this normal and if so are we suposed to choose betwen using one or the other? Steve Tag: Interacting with modal and modeless forms Tag: 102873

    - Embed SQL2K5 Express into windows apps I have developed a desktop applicatio with synchronization feature. I wanna embed the sql into my application, and have following questions: 1. I can't just attach the database file (.mdf) as connectivity components are required for sync function, right? 2. When install the sql2k5 express, the default instance is MachineName/SQLEXPRESS, is there anyway to set it to Local/SQLEXPRESS? 3. Is there any sample code on the Internet in Visual Basic I can look at? Any help and advice are very much appreciated!! Carol Tag: Interacting with modal and modeless forms Tag: 102872

    - Change the value of a Listview subitem I have a ListView box in my form which is populated by an array : Dim item2 As New ListViewItem(index & ".") item2.Checked = True item2.SubItems.Add(r.description) item2.SubItems.Add(r.host) How can I change the value of these subitems afterwards? For example: I have 2 forms. One with the ListView box and one with some textfields to enter some data (description, host, ...). After a user has entered the data everything is stored in an array (r.xxxx) and two fields (description and host) are shown in the ListView box as a reference. Now the user selects this entry again and clicks the button "Edit". The second form opens again showing all previously entered data and the user does some changes, eg. modifying the "host" entry. After clicking OK the value for "host" in the ListView box should be updated. Everything works already (all forms, add, edit, remove, storing data (also edited data) in an array, etc.). Only the update of the ListView is missing. Tag: Interacting with modal and modeless forms Tag: 102864

    - ClickOnce and login on as a different user Hello group I'm developing an C# Windows Forms application that I would like to deploy using ClickOnce. One of the computers that the application is deployed on, is a computer that is always loged on as a generic "controlroom" user. This is necessary for some of the other applications running on the computer. On my application, the user should always logon as himself or herself. Therefore I need to present a login form to the user as the first thing. I have been considering using RunAs, but I'm not sure that is possible along with ClickOnce, at least nok using the GUI of RunAs. I have looked at the Windows API LogonUser, but that seems to be requiring unsafe code permissions and FullTrust, and I was hoping that I could avoid giving those permissions to the application, especially when I'm deploying it using ClickOnce. Do you have any alternative suggestions? Thank you for your answer. Regards Anders Olsen Tag: Interacting with modal and modeless forms Tag: 102854

    - Can't print in landscape orientation Hi group.

Using .NET framework 2.0 This code prints in portrait orientation in any printer no matter what I do, ignoring the 'MyPrintDocument.PrinterSettings.DefaultPageSettings.Landscape = true' statement in the BeginPrint event handler. It's not a printer problem. Any help will be greatly appreciated. Tag: Interacting with modal and modeless forms Tag: 102853

    - How to find the parent form for a ContextMenuStrip Hi, I have a ContextMenuStrip that is used on various forms. When somebody opens the context menu on a specific form (e.g. Form2) and clicks a menu item, I need to execute some action on that form. Is there a way to determine the form from which the context menu was invoked in the click event handler? Usually I do this with Control.FindForm() but that does not work for the ContextMenu.

    - FontDialog Only Allows Integrals? I've noticed that the FontDialog only allows positive integers as input when you show the dialog. Is there some reason for this? The font that it returns allows singles and I can't really find anywhere that explains why this might be. We're writing our own FontDialog (due to some other limitations), and we're trying to find out if there is a practical reason for this or if we should allow any positive decimal number. Thanks.

    - drilling down in a datagrid I have a datagrid with a dataset as its datasource. Its datamember is a table that has 3 datarelations defined in the dataset. I would like to capture the click event on the plus sign to avoid allowing the user to select which datarelation to use to view child records. Can I do this without subclassing the datagrid? If not, what is the best way to grab onto the plus-sign click (since datagrid.hittestinfo doesn't distinguish the plus-sign click from any other rowheader click)?

    - Custom title bar size in Non-client area Hi! I am trying to make a custom size title-bar in the non-client area of the form. I've tried hooking to the NCCALCSIZE message with this code: case (int)Native.NativeMethods.WindowMessages.WM_NCCALCSIZE: if (m.WParam == IntPtr.Zero) { // get the NCCALCSIZE parameters NativeMethods.NCCALCSIZE_PARAMS csp; // Marshal them from the pointer csp = (NativeMethods.NCCALCSIZE_PARAMS)Marshal.PtrToStructure(m.LParam, typeof(NativeMethods.NCCALCSIZE_PARAMS)); // Resize the client area to make more room above csp.rectBeforeMove.top-= csp.rectBeforeMove.top/ 2; Marshal.StructureToPtr(csp, m.LParam, false); } else { base.WndProc(ref m); } return; However, it just says that I am trying to read or write into a protected memory. If i modify any other value, i.e. right, left or bottom of the same rectangle, it works OK yet there are no changes. I also tried changing the other two rectangles, but the result is never what I need. I would really appriciate any suggestions on this topic.

    - Bug in SaveFileDialog Hello there, I found a bug using SaveFileDialog and I was not able to find any similar issue on the web. This seems to apply to any .NET Applications using SaveFileDialog. To perform the bug: 1. Open a SaveFileDialog and save any File, e.g. TestDocument0.txt: This should create a document named TestDocument0.txt 2. Call once again the SaveFileDialog, select the TestDocument0.txt you created in the File Window: The name of the File appears in the Text Box, left of the "Open" Button. (Notice, the Selected File is still grayed in the File Window) 3. Rename the Text in this Text Box, e.g. TestDocument1.txt: (Notice, the Selected File is still grayed in the File Window) 4. Click in the File Window, but not on a folder or a file. The previously selected File is not grayed anymore, the focus is set on nothing. 5. Press the "Save" Button, you will get the following Waning: "File TestDocument0.txt already exists. Do you want to replace it" The error is obvious, it should save my file as TestDocument1.txt, and not TestDocument0.txt, as it appears on the Text Box. Could you reproduce such strange behaviour?

    - usercontrol with readonly property that can be set at design time Can someone tell me if it's possible to create a property for a usercontrol, that is essentially readonly, but able to be set via the designer before runtime? I have a property for a control that I want to set essentially one time. This property is basically a static property that can change at the developer's wish, but only one time. I need to be able to reference the property later. I've tried setting the property to readonly, but that hides it from the designer properties window. I've tried various attributes to no avail (i.e. DesignOnly(true)). When I do this, I cannot set the property at design time(the value doesn't hold). But in later code I can change that property without fail. I'm confused. Please help. Tag: Interacting with modal and modeless forms Tag: 102766

    - BackgroundWorker and RunWorkerCompleted event I have a BackgroundWorker component that I am using as: Dim arguments As XmlSentArguments = New XmlSentArguments arguments.TransactionId = 10 arguments.OrderId = "na" workerThread.RunWorkerAsync(arguments) The thread seems to get started and it completes. I put a breakpoint in DoWork that looks like: Dim worker As BackgroundWorker = _ CType(sender, BackgroundWorker) e.Result = BackgroundXMLSent(e.Argument, worker, e) Since I am not interested in cancelation or progress the BackgrounXMLSent routine just looks like: Function BackgroundXMLSent(ByVal arguments As XmlSentArguments, ByVal worker As BackgroundWorker, ByVal e As DoWorkEventArgs) As String Return XMLSent(arguments.TransactionId, arguments.OrderId) End Function I have verified in the debugger that the routine XMLSent is returning so BackgroundXMLSent is returning. The problem is the the event RunWorkerCompleted does not get fired and the component always shows IsBusy as True. Any ideas as to why this event is not firing and why the component is always busy after the first call? Thank you. Kevin Tag: Interacting with modal and modeless forms Tag: 102765

    - Accelerator keys broken in Winforms I'm having a problem with accelerator keys (also sometimes refered to as shortcut keys or mnemonics) on Winforms. To reproduce, simply do this: 1. create a new C# "Windows Application" project (I'm using VS2005) 2. Add a button to the form and change its default Text from "button1" to "&button1" Now run the app. Press the alt key on the keyboard and the keyboard cue is displayed (the 'b' becomes underlined) as it should. Press the alt key again and the underline does not go away. You will also notice that pressing the 'b' key fires the button's click event regardless of whether the alt key was ever pressed, or whether the cue is visible. Surely this isn't "by design" (Menus don't work this way! OS supplied dialogs don't work this way!) Any pertinent suggestions on how to work around this would be welcome.

    - Smart Client Deployment I hope this is an easy question to answer. In developing a smart client application, I'm lead to beleive that only assemblies that have changed get updated during the next time the application runs. But if you have a assembly that is referneced by other assemblies, don't they need to get recompiled which changes there version which in return everything needs to get downloaded again. Can somebody please explian if this is true or not. Thanks. Tag: Interacting with modal and modeless forms Tag: 102747

    - Getting Icon of Files All - How can I get an icon associated with a particular file extension and then get the icon displayed in a picturebox? I have an app with a picturebox. The picturebox displays pictures and other files stored in SQL. If the SQL data is an image, it displays the image but if it is, say a word doc, it displays an image I created that says "Not an Image". I would like to display the icon associated with the particular file type inspectead. So, when a user adds a word doc, the icon is shown in the picturebox or adobe or whatever else the user might save to the database. Better even yet, would be to load a preview of the document into the picturebox, like Adobe does in the "thumbnail" view of a windos folder.

    - hiding form from alt-tab In the 1.1 version of the framework setting ShowInTaskbar to false and FormBorderStyle to none was enough to stop a form from showing up in the alt-tab list. After porting the app to 2.0 all the forms now appear in the alt-tab list. What do I need to do to hide the forms from the alt-tab list?

    - Can "InitializeComponent()" info be captured Hi there, Don't know if I picked the correct NGs or not but maybe someone can steer me in the right direction. Does anyone know if a class exists to capture the same info now wrapped in "InitializeComponent()". I want to capture all form details for a given form at design time (properties and controls) but I can't find anyway to do it. Note that reading a form's ".resx" files won't do either (it's only good for localized forms but in any case, it doesn't always provide complete info). Thanks very much.

Hi all

I am writing a piece of control software that monitors data from a data
source and controls the data source peripherals.

I am using a Modeless Form to monitor the data and to change the data source
parameters in real time.

I am using Modal Forms to control the peripherals, because these are popped
up, used and closed again when required.

My problem, is that whenever I open one of the Modal Forms, the Modeless
Form no longer responds to input.

I could do this in C++ / MFC by giving the Modeless Form a NULL owner, but
it seems as though in DotNet a NULL owner impies the Main Application Form.

Does anyone know how I can get around this problem.

Laurence
