    - PropertyGrid with duplicate DisplayNames Hi group, I have a problem using the PropertyGrid. I'm using a PropertyGrid to show a dynamically generated option dialog. I use an ICustomTypeDescriptor implementation together with a custom PropertyDescriptor that fakes out the needed "properties" for the grid, the actual values coming from a different data source, that can also changed programmatically. The PropertyDescriptor fakes a human friendly DisplayName and an unique PropertyName that is only used internally. Problem: When doing a propertyGrid.Refresh(), GridItems with duplicate DisplayNames are not handled correctly, specifically: If I change the value for any but the first one (in current sort order), after the refresh the FIRST one is always selected, and it shows the string representation of the currently changed entry (however, it DOES paint the value representation correctly). The string representation is only displayed incorrectly, i.e. it is not written back, and after any focus changes, it is displayed correctly. Also, if I make the DisplayNames unique, or the PropertyType differs, the problem goes away. It also does not depend on the PropertyDescriptor/ICustomTypeDescriptor combo, but happens even with static properties (just checked ;-)) Has anyone else encountered this or a similar problem and/or has any tips? Regards Jasper Tag: Select Text of Label Tag: 99815

    - WindowsService stops just after it's started - remoting hi, I created WIndowsService to host SAO object. Everything was ok before, but when I get back to it a few days ago i realized that it doesn't work properly. So what I did wrong? Service host remote object so it has work to do and service shouldn't be stopped. The only solution I see is to create Thread with simple loop to keep my service runing - but I know it's bad solution. Please help me with my problem. Piece of sourcecode: internal partial class Server : ServiceBase { private TcpServerChannel chan; private ChainingDeamon chainingDeamon; public Server() { InitializeComponent(); } protected override void OnStart(string[] args) { try { this.NetInterfaceSetup(); } catch (Exception e) { MessageBox.Show(e.Message, "DesServer Startup Error", MessageBoxButtons.OK, MessageBoxIcon.Error); this.Stop(); } chainingDeamon = new ChainingDeamon(Application.StartupPath); } protected override void OnStop() { } private void NetInterfaceSetup() { this.chan = new TcpServerChannel(48004); ChannelServices.RegisterChannel(chan, true); RemotingConfiguration.ApplicationName = "DesServer"; RemotingConfiguration.RegisterWellKnownServiceType(typeof(DesServer.AdminProviderFactory), "DesServer.AdminProviderFactory", WellKnownObjectMode.SingleCall); } } regards Martin Dz Tag: Select Text of Label Tag: 99812

    - Problem with multithreaded application (Cont.) Let me be more explicit on the problem: i've been making some testings on my application and i realized that the application hangs in this situation: I have a main window created in the thread which called Application.Run so it has the message loop right? Well, then i have another thread wich represents an entity which has to do its own operations (worker thread created with the thread object) .Then i ask my thread object to show a monitor where it has to write its progress in the operation, this monitor is a non-modal dialog. The worker thread calls a method to obtain the form which represents that monitor: this method will do a call of the Invoke method in the form object which represents the main form of the application and which was created in the thread which called the Application.Run method,follow me? : ) .this invoking is to ask the UI thread to create a monitor form object (i have to create the monitor object in the UI Thread as it will be a non modal dialog which i will show using its Show method so it won't have a message queue by itself ,this is the opposite to what happens if i want it to be a modal dialog:then i call the showdialog method and it will have its own messagequeue and it is not necessary for it to be created in the UI Thread) well thn the worker thread gets its monitor form object and do an Invoke to call its Show method to display it. Periodically the worker thread will do an Invoking to call a methos wich updates the fields of the monitor object. Well everything goes fine but when the monitor is running and i start moving the main form from one side to other of the screen then the hang of the application comes up. I think that it could be because i created the monitor object in such a way that it share the messagequeu of the main form of the application(creating this object in the UI Thread). The problem is that i havent found the way to give a non modal dialog its own message queue independent of the message queu of teh main form. anybodu thinks that this could be the problem????

    - Problem with multithread application Hi there.Im building a multithreaded application which uses forms and im having some problems possibly due to my inexperience. The project is being developed in C# with visual studio 2005. I have a main thread which executes Application.Run() (so it has the message loop for the interface) and later i create more threads that are executing and in some situations have to do some operations in the UI. Some threads also query the UI the creation of non-modal dialogs to show information "on the fly". There arent cross-threaded operations in the UI, im sure of that. All the operations have been queried using the InvokeRequired attribute and the Invoke Method (i have used only the Invoke method instead of using BeginInvoke too) so all the operations on the UI are done in the Thread tha run Application.Run (the UI thread). When i execute my application everything goes fine buty sometimes when i execute it and push some button of one of the windows or when i close one of that windows etc etc my application hangs (well i dont know if my application but at least the UI). I think that the problem is in that im not considering some issue of the using of the UI in multithreading applications, maybe it is taking place a deadlock when im quering the UI tread some operations from different threads Â¿someone can advise me or has any idea about what can be happening? thanks Tag: Select Text of Label Tag: 99795

    - Win application freezes on datagrid scroll event Hallo, I'm experiencing an eerie trouble using datagrids on Windows application with .NET framework 2.0 Being concise, I say that my applications polls the serial port by means of a separate thread. When some information is found on the tool connected to the port (a GSM phone), such an information (SMS) is put in the db and then an event is raised. When such an event is raised, the delegate invokes an appropriate method that refreshes the datagrid: every row in the grid is one received SMS. The refreshing is made by the separate thread, so it is called the appropriate method that enables separate threads to interact with the objects and controls of the UserInterface belonging to the main thread, as it is meant to be. Ok, everything works fine but, say that the datagrid control can show 16 items before the vertical scrollbar appears, when the 17th item has to be shown, instead to visualize the vertical scrollbar, the whole application freezes. No errors are thrown: just freezes - not responding application. Need to kill and restart, and so it's ok: vertical scrollbar appear. I've to say that this behaviour doesn't happen always. Almost always. I mean, sometimes 20 or more SMS are found in the GSM and correctly shown in the datagrid with scrollbar, but the most of times when the 17th is shown, application freezes. I'd be glad if someone could shed some light upon this strange, and unpredictable, event. Many thanks, Paolo P Tag: Select Text of Label Tag: 99788

    - Use MeasureString to determine required height I'm trying to create a label control in VB.NET2005 that will automatically change it's height to fit the content. To do that i'm using MeasureString to determine required height for a set width. What i found is that MeasureString sometimes returns the height which is smaller then it should be and it seems to depended on the width. So the question is am i doing something wrong or it's a bug. If it is a bug, can someone recomend a reliable workaround. Here is a code that used to test this. When width is set to 570, the last line is not visible. When it's set to 590 all is OK. Sub TestMeasureString(ByVal g As Graphics) Dim s As Size Dim f As Font = New Font("Arial", 11.25, FontStyle.Regular, GraphicsUnit.Point) Dim str As String = New String("W"c, 1000) & " END" s = g.MeasureString(str, f, 570).ToSize 's = g.MeasureString(str, f, 590).ToSize g.DrawRectangle(Pens.Black, New Rectangle(New Point(0, 0), s)) g.DrawString(str, f, Brushes.Black, New Rectangle(New Point(0, 0), s)) End Sub Tag: Select Text of Label Tag: 99783

    - Question on Inheriting Controls I have a project which is a Windows Form "Wizard". Each "page" displayed in the main Wizard form will be a user control. Each of these user controls will share many similar attributes. So it seems natural for me to create a base user control class and have all my "pages" inherit from it. But it seems that VS2005 really isn't happy doing this unless the base class is compiled and put into an assembly other than the one containing my project. The visual designer get al hosed up and complains. I can force it all to work by hand-coding some changes but this seems way harder than it should be. Is there something I am missing here? Thanks.

    - RichEditBox speed Is there anyway to speed up the selecting and coloring of text in a richedit. The parsing of the text is nothing in comparison with how long it takes these two calls to take place (over many lines): rtb.Select(currentPos, myLine.Length); rtb.SelectionColor = myColor; From my research, there are a few ways to speed up the richedit but none of them help speed up the coloring process: 1) Inherit from the RichEdit and in an overloaded WndProc, ignore WM_PAINTs while updating 2) Use SendMessage to pause redraws/events (EM_SETEVENTMASK, SETREDRAW)while updating 3) Hide the RichTextBox while updating (seems to work the best...but it is still slow) Does anyone else out there have any better suggestions? I want to color the entire richeditbox in one sweep...so I don't have flickering or other noticeable side-effects caused by scrolling. I'm not looking to use a 3rd party control either for a number of reasons. TIA! sb Tag: Select Text of Label Tag: 99769

    - Adding 'object' to Treeview? I have a bunch of related classes that I want to add into a Treeview with a hierarchy. However, Treeview doesn't support the insertion of the root 'object' type into the nodes, which surprises me. I just wanted to add them in and have the mouse events fire back with the reference to the object clicked on. I figured I'd have to override ToString in my classes to have them show up in the treeview in the right way and that would be that. But to my surprise it doesn't seem to work like that and it seems like I have to start messing with data binding... which just seems so overkill for the task that it must be the wrong thing to do. Can't I just add 'object' types like I can to the collection classes? What should I be doing instead? Thanks for any help! Tag: Select Text of Label Tag: 99761

    - Edit different data types in a DataGrid in the same column on different rows Hi All Hopefully someone out there can answer this. I have a data source that displays a set of property names and values (each name/value pair will be displayed on a different row). I want to be able to enable the data source to be edited through the grid, but each of the values on different rows may be a different data type. I know I can apply a column style to set a whole column to display a ComboBox for a selection, a DateTimePicker, etc., but I'd like to know if there's a way to apply the style on a row-by-row basis. In doing this I should be able to display all the property name/value rows and have a different edit mode control appear for the value in each row depending on its data type. I should not neglect to mention that the data type of the value column can be defined programatically, as it's also held in the data source to describe the type of data in the value column. Can anyone please advise if this is possible, or if you'd like more information to clarify the problem. Thanks in advance, Sam. Tag: Select Text of Label Tag: 99728

    - studio deleted my resx file, and now it won't rebuild it properly! I'm using Visual Studio 2003. I have a C# Forms app with several forms. While working, Studio asked to check the .resx file of a particular form out of SourceSafe. It then completely erased the .resx file, leaving the form empty in the Designer. However, all the code is still in the .cs file! Most solutions I've found say to delete the offending .resx file, and Studio will rebuild it for you. Unfortunately, that's not happening here.

    - Setting combo box items property? I am building a user control that has a combo box (comboBoxMain) as a constutient control. The user control has an Items property, which will set the items of the combo box. I want the user control Items property to be browsable at design-time, so the user of the control can click the properties, enter a list of items in the String Collection Editor and have them appear in the combo box. Here's the code I'm using now: [Browsable(true)] [EditorBrowsable(EditorBrowsableState.Always)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)] [Editor("System.Windows.Forms.Design.StringCollectionEditor,System.Design", "System.Drawing.Design.UITypeEditor, System.Drawing")] [Description("The list of objects in the combo box")] public ComboBox.ObjectCollection Items { get { return comboBoxMain.Items; } set { comboBoxMain.Items = value; } } The Editor attribute brings up the String Collection Editor, but it isn't retrieving any items I place in the combo box. And nothing that I enter in the editor is making it back to the combo box. What do I need to do to complete the connection between the user control Items property and the combo box Items property? Thanks. -- David Veeneman Foresight Systems Tag: Select Text of Label Tag: 99716

    - No touch deployment - internet cache full We have had a few instances in our organization that the user was unable to run a no-touch deployment exe from our intranet. Clearing their full internet cache corrected this problem. This happened in 2 scenarios: 1. When trying to run the no touch .exe over the intranet would do nothing. 2. When trying to run the .exe over the intranet the user would run their old cached copy of the application and not download the latest from the server. In both scenarios clearing their internet cache and launching the application again corrected this problem. I thought the idea with internet cache is First In, First Out... in thus... cache would be cleared to accomodate new temporary internet files. Is this correct or is there an issue with no-touch deployment in this regard. Has anyone else ran into this problem, and if so what solutions have you come up with. Remember we have a large organization and no touch deployment applications are being used by 100+ individuals. One way I know would be to write a login script to clear the internet cache... of course.. not every user will reboot their PC every night... and isn't ideal for other reasons. Thanks in advance...

    - ConfigurationManager app.config Dear Friends, I have been trying to get the following to work properly, but with little luck. I have created a class that inherits from ConfigurationSection. I then added a <configSections> ... <section name="test"> in a new app.config (which I added manually to my project). It seems to be able to read the app.config, but not write back to it. I seem to have a partial/temporary working config file that is created in the bin\debug directory called XXX.vshost.exe.config. It seems to temporarily store the proper values when I save the settings, but seeing that it is rebuilt dynamically everytime the application is run, I lose all settings. What gets to me is that the settings are not written to the app.config file. I get no errors when I execute .Save method. Just no info is written. Does anyone have an example in VB.NET or a guide/tutorial, etc... In essence, I want to use my ConfigurationSection derived class to be able to load and save a custom section in the app.config file as I have seen others do, but can't get it to work myself. Also, any help on how to properly set up an app.config file with the <configSections> etc... properties. Regards, Giovanni Tag: Select Text of Label Tag: 99713

    - Data binding a ListBox to a List<T> I have 2 list boxes on the form. Each listbox is bound to a different List<T>. My goal is for the user to select an item in ListBox1, click a button, and have that item moved to ListBox2. The way I approached this was to have a populated List<T1> bound to ListBox1. I set the DataSource, DisplayMember, and ValueMember properties of ListBox1 and the items in the List<T1> were correctly shown in the listBox. I bound ListBox2 to List<T2>. Since List<T2> had nothing in it, ListBox2 correctly showed no items. I thought that if I removed an item from List<T1>, that ListBox1 would update to reflect that but it doesn't seem to work that way. Similarly, I thought that by inserting an item into List<T2>, that the ListBox2 would update to reflect the addition. It does not seem to work that way. How can I get the ListBoxes to update and show the current contents of their respective List<T> objects? Is there a way to "rebind" them? Thanks, Chris Tag: Select Text of Label Tag: 99712

    - Open SDI form from MDI Parent I have an application that has a main mdi parent window to navigate and perform basic function. I need the mdi window to accomplish everything I need in there. I also need to be able to open up records in a new SDI window. When I attempt to open the form it is not given focus and is opened behind the mdi parent form. How do I give it focus and have it be opened on top. I do not want it always on top. Just when it opens. Here is my code. Dim exists As Boolean = False For Each f As Form In My.Application.OpenForms If f.Tag = nodeTag.Substring(1) Then exists = True f.Activate() End If Next If Not exists Then Dim act As New frmActivities act.Tag = nodeTag.Substring(1) act.Show() act.Activate() End If Tag: Select Text of Label Tag: 99695

    - deriving DataGridTextBoxColumn - behaviour on new rows Hello I have derived a class from DataGridTextBoxColumn and am getting some behaviour which I do not understand and I would like to know where I am going wrong. The problem is like this. I have a datagrid, lets say with four columns. Two columns have my derived style and two have the default DataGridTextBoxColumn. When you make changes to the datagrid there is a button to press to validate and then send the changes back to the database to be written. The problem comes when you click in the "new row" at the bottom of a datagrid (the blank row with the star in the header). If you click into and then straight off the default DataGridTextBoxColumn in the new row, the UI indicates that no new row has been created, and if you then save the changes, no new rows are added to the database. However when you click on and then away from the derived class, the UI performs in the same way - it appears as if there are no new rows added, but when you click save changes you get a new row written to the database - with all the row default values. This implies that the row was created in the underlying DataTable, but that fact was not reflected in the UI of the datagrid. For reasons that I shall not go into this is a big problem for my application. What I would really like to know is what I need to do to get my derived column style to behave in the same way in this situation as the DataGridTextBoxColumn. I.e. click on and away - the UI implies that no row has been created and that is in fact the case when writing changes to the database. Thanks in advance for any light that can be shed on this issue! I've been reading lots of articles on MSDN but none that I have found seems to cover this situation! Best Regards David Smith Tag: Select Text of Label Tag: 99688

What about using a TextBox control with the Enabled property set to false?

Hi,

I think this is a very relevant question because most of the dialog
boxes in Windows have this facility. To elaborate, when you hover your
mouse over most labels, the cursor changes to an I-beam, and you can
select and copy the text. And they do seem to be *normal* labels.

Isn't there an *easy* way to do this in VS 2003 ?

P.S.: (Easy <> using Interoperability)

Regards,

Cerebrus.

Sorry. I made a mistake. I should have said to set the ReadOnly property to
true on the TextBox. Do not modify the Enabled property. If you set the
ReadOnly property to true, and set the BorderStyle to None, then this
describes the scenario that you outlined - what appears to be a Label with
an IBeam, select and copy text, etc.

I must confess that's a really easy way to do it. I'm kinda embarassed
to say that such a simple thing did not occur to me.

I was thinking in terms of deriving a custom label and manually
implementing all that functionality !

Thanks a lot, Tim.
