    - Limit to range of colors displayed by Label control? Hi, I was just curious to know if there was a limit to the range of colors a label control can display. For instance if I set a label control's ForeColor to 28, 23, 15 it renders black (on my system, at least - but I'm running an nVIDIA GeForce 440 MX 64MB card running in 32-bit color, which should be plenty able to render that properly). Anyway, it occurred to me that perhaps the label had a restricted color range, and if this is the case, which other controls might this restriction apply to? thanks! evan k. stone | software engineer ---------------------------------------- santa rosa, ca, usa Tag: ProcessCmdKey up to parent form Tag: 102886

    - Question about DataRows/DataGrids Hey all, I have a question about using DataRows (and ultimately, its interplay with a DataGrid) So I create my DataSet, create a DataTable, configure it with columns and then add rows like so: (C++ .NET) DataTable* table; //assume setup DataRow* row = table->NewRow(); //columns 0,1, and 2 are all setup in the table row->set_Item(0,fi[i]->get_Name()); //assume fi[i]->GetName() returns some string* row->set_Item(1,S"Queued"); row->set_Item(2, S"---"); table->get_Rows()->Add(row); After I have added the row to the table, can I still use the DataRow object to change data in the row, or is this a no-no ? Do I need to wrap the changes with calls to DataRow::BeginEdit and DataRow::EndEdit? After I have added the DataTable to the DataSet and, set a DataGrid to refer to the DataSet and display the DataTable I setup, can I still change stuff then? If I do, what is the proper way to update things? Should I call DataGrid::Update()? I'm dealing with some nasty problems where I get the "No original data" error from my datagrid while I'm updating literally all the rows in the table by just directly referring to the DataRow object I got from DataTable::NewRow() in the beginning. tia, rj ryan Tag: ProcessCmdKey up to parent form Tag: 102885

    - Windows Service and Threading What is the proper way to terminate a Thread in a Windows Service? I have a windows service which starts up three threads which run in a while loop as long as a boolean flag is set to true. These threads each sleep for X ammount of time then start processing again. Since this is a service it's basically running in an infinite loop. When the user goes to stop the service, I have been calling the Thread.Abort() method, which throws a ThreadAbortedException. I've also tried using the Thread.Interupt() method to wake any sleeping threads, but that too throws a ThreadInteruptedException. What is the proper way to kill these threads in the 30 second timeframe that the windows service framework gives a service to respond back? If catching these Exceptions are the correct way to stop the service, what is the correct way to know if the service actually dies on it's own for some reaon (i.e. god forbid locking)?

    - TLB using problem I created very simple Class Library in VB 2005 (let's call it COMInterop). I set Register For COM Interop property to true to make it accessible by VB6 program. After I compiled it, I got COMInterop.dll and COMInterop.tlb files, I have no problem with using both of them on the machine where the project was compiled - TLB with VB6 clients and DLL with VB 2005 clients. I copied the tlb and dll files onto another machine and registered TLB file with regtlib.exe. I've got a message about successful registration. I created a new VB 2005 Windows Form project, added the reference to COMInterop.dll and it works fine. I created VB6 project, added a reference to this TLB. I'm trying to use it with the simple code which works with VB 2005, but produces an error in VB6: Run time error '429': ActiveX component can't create object The code in client: Private obj As COMInteropTest.COMInterop Private Sub Command1_Click() Set obj = New COMInteropTest.COMInterop 'The error occurs on this line MsgBox obj.myFunction End Sub What am I missing? How do I make VB6 client work with TLB on any machine, not only on the machine it was created? Thank you Al Tag: ProcessCmdKey up to parent form Tag: 102881

    - Treeview problem I'm trying to create a treeview that will show data from access database in hierarchical way. Database structure is: ID, FirstName, LastName, IDBoss - IDBoss is referenced to ID.

    - Interacting with modal and modeless forms 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 Tag: ProcessCmdKey up to parent form Tag: 102878

    - 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: ProcessCmdKey up to parent form 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: ProcessCmdKey up to parent form Tag: 102854

Any info would be appreciated :) -sb // Entire program using System; using System.Windows.Forms; static class Program { [STAThread] static void Main() { Application.Run(new Form1()); } } public class Form1 : Form { public Form1() { this.AllowDrop = true; this.DragDrop += new System.Windows.Forms.DragEventHandler(this.Form1_DragDrop); this.DragOver += new System.Windows.Forms.DragEventHandler(this.Form1_DragOver); } private void Form1_DragOver(object sender, DragEventArgs e) { e.Effect = DragDropEffects.Copy; // We'll accept any kind of drop } private void Form1_DragDrop(object sender, DragEventArgs e) { throw new InvalidOperationException("DragDrop exception."); // nothing happens here } } Tag: ProcessCmdKey up to parent form Tag: 102784

    - webbrowser, net 2.0, navigate to name tag Hello, I want to use the Webbrowser control (Net 2.0) to display our help files. webbrowser1->Url = gcnew Uri("/Terminal.html#Terminal_CompNo"); So, I want 1) to display the file "/Terminal.html" and 2) to move to the name tag "Terminal_CompNO". Display the file - is OK but the move to the name tag - failed. This was the same with the OCX-Control, there was an special func 'NavigateByDoc'. Has anybody an idea to make an work around or anything else. Frank Iversen Tag: ProcessCmdKey up to parent form Tag: 102778

    - 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? Thanks for your help Picander Tag: ProcessCmdKey up to parent form Tag: 102771

    - control in user control to adjust with size I have a datagrid control encapsulated inside a user control. When I use the user control on a form and change its size, is there a way to get the datagrid inside the user control to adjust with it accordingly? Thanks.

    - 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: ProcessCmdKey up to parent form 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: ProcessCmdKey up to parent form Tag: 102765

    - Can't Create New Data Connection Just installed Visual Basic 2005 Express Edition. When attempting to link to a data source which is a ms access database I get the following error (if I wrote it down properly). Format of the initialization string does not conform to specification starting at 0. I thought it would be a bit easier to expose the project to my data, but no. Any help will be appreciated.

    - 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.

Hello,

I have an MDI application which manages smaller tool windows
(implemented as separate, modeless Forms), sort of like Adobe
Photoshop. The menu items in the main app form can be activated using
shortcuts.

When I do something in one of the tool windows, keyboard focus changes
to the tool window. Is there a way I can have the shortcuts for the
menu items in the main app work when keyboard focus is in the tool
window?

I was hoping there would be a solution like overriding ProcessCmdKey,
and calling the tool window's ParentForm.ProcessCmdKey(), but obviously
I can't. Is there another way to have shortcuts processed by a
different form than the one which has keyboard focus?

Thanks,
Jon
