    - IE and XML problem. I'm having trouble convincing IE to display my XML when I'm using it in my application. I'm creating XML using XmlTextWriter, and then Load() it to IE. The problem is that in the way, a space is inserted after every character (Like this < ? x m l v e r s i o n = " 1 . 0 " ? >) Which isn't valid XML, of course. Here is my code: private void ShowHtml(Item item) { ShowHtml(RoarApp.CurrentApp.ItemToXml(item));//Generate VALID XML } private void ShowHtml(string Html) { IPersistStreamInit Persist; Persist = RoarBrowser.Document as IPersistStreamInit; Persist.InitNew(); Persist.Load(Interop.GetStream(Html)); } //This is the Interop.GetStream method public static UCOMIStream GetStream(string Data) { IntPtr ptr = Marshal.StringToHGlobalAuto(Data); UCOMIStream retVal=null; CreateStreamOnHGlobal(ptr,true,ref retVal); return retVal; } Tag: ErrorProvider Tag: 62931

    - SEHException on ShowDialog Hi everyone, I'm getting some strange errors regarding the ShowDialog() method. I have an MDI application. If I attempt to show a dialog box (ShowDialog) from a child window, either an SEHException or NullRefernceException may be thrown. This only seems to happen when I have other, specific child windows open in the background. I am using databinding, and as far as I can tell, these exceptions are thrown for windows with listboxes or datagrids that are bound to tables in a dataset. If I open one child window only, no exceptions are thrown, but if I open a different child window (one with, say a databound datagrid and listbox), then flip back to the original window, and attempt to open a dialog, then the exceptions are thrown. I've read elsewhere that this can be caused by calling the Application.EnableVisualStyles - but I'm not doing this. Any help would be greatly apprecited. Thanks, Dave Hagedorn Tag: ErrorProvider Tag: 62929

    - Communicating With A Service Via A GUI - Need some ideas.... We are trying to write a simple GUI front end to communicate with a service. We need the GUI to make the service fire certain events if the user needs to re-perform certain tasks manually, and possibly return a result string with back to the user from what the service did, records processed, errors, etc. We are thinking there should be a system tray icon as well that the user uses to open the GUI as needed. We tried to keep it simple, and just make a service out of our existing GUI form, and set it to interact with the desktop. Apparently, right click menus do not work with system tray service apps, and the icon itself doesn't go away as expected when the app shuts down. All in all, not a very elegant, stable or confidence inspiring solution. We then tried to make a separate GUI app, and keep all UI out of the service. The process controller I think we can only SEND integer commands, so it is not really powerful enough. Should we be looking at remoting? Is there an easier way? We have been through a half dozen examples on MSDN, various articles, etc. and by the time we try to put a remoting sample together with a service example with a system tray icon example, then get all the .dll's created, build an install program, then try to get it installed on a test machine it all falls apart. Any ideas on this? We have been doing stuff like this for years with pre-dot net versions of VC, but just can't get our heads around doing it now with .NET. Thanks.... Tag: ErrorProvider Tag: 62928

    - Creating Crystal Reports Dynamically Hello All, I am using Crystal reports in my windows application. Currently the method that I am using to create the report is as follows: 1) Create a SQL Stored Procedure that would return the data for the report. 2) Create a Dataset from the SPcreated in Step 1 3) Create fields on the report mapping them to the fields of the dataset. 4) At run time, fill the dataset so that the report displays the data to the user In the above approach, all my report fields are decided at design time. If I make any changes to my stored procedure or I want to add new fields on the report, I have to follow the above steps all over again. On changing the data source, the fields on the report are lost. I want to create the report fields at run time or in some better way than the above mentioned method. I need some examples and explanation on how to go about doing all this. If any one has other ideas in creating reports efficiently, it would be highly appreciated. Thanks in advance Mithun Tag: ErrorProvider Tag: 62917

    - How to connect Click-Event with a user-control on a form? I have a previously selfcreated user-control which contains a picturebox and some additional code, also included is a method that changes the displayed Image in the Picturebox on Clicking. This works fine so far. Now I place this user control on a new form and i want it to fire a Click-Event on my form when a user clicks it. The Image in the Pictuebox changes on clicking but the Eventhandler on my form doesnt fire anything on clicking! I need a possibility for the users of my user control to write their own code for a click-event on that control. I read something about user controls being special with events but i dont get to the point yet... Thanks in advance for your help, Jan Tag: ErrorProvider Tag: 62914

    - control in web page fails if only in GAC I'm trying to put a DateTimePicker on a web page, using <OBJECT classid="System.Windows.Forms.dll# System.Windows.Forms.DateTimePicker" etc.> (without the line break after #) but it just puts up an empty box with a scrollbar, indicating some kind of failure. With some experimenting I've found that, despite what everyone says, this sort of thing never succeeds in using an assembly from the client's GAC, but works fine if the assembly is in the same directory with the web page. So, I tried copying System.Windows.Forms.dll from the GAC into the web directory (ugh!), but then I just got an image icon and it still didn't work. The examples everyone gives are always of a derived class, never the standard controls. Am I missing something obvious, or is this basic functionality broken? Tag: ErrorProvider Tag: 62895

    - Form layout corrupted with DPI set to 120 I have a Tab control on my form. Inside the tab control, I have child controls that expand (anchors) to fill the tab as the screen is resized. When working in 96 DPI all is fine. When running on 120 DPI, the first tab that is displayed during startup has wildly set sizes for the child controls (usually way too big). The other tabs' controls are all OK as your tab to them. Going back to the first tab doesn't fix it though. The first tab that is displayed changes depending on configuration settings. Whatever tab happens to be first drawn, is the one with the problem. If that same tab is not the first one drawn, all is fine. The problem is apparent for Win2K and XP. However, Win2003 draws fine. So the assumption is that MS fixed something in that release. Unfortunately - I don't know what the work around would be. Help?! Tyke Tag: ErrorProvider Tag: 62894

    - System.Resources.MissingManifestResourceException I get the following error with a single form during runtime: "System.Resources.MissingManifestResourceException: Could not find any resources appropriate for the specified culture..." etc. The error is raised during InitializeComponent on the following line: Me.Button1.Image = CType(resources.GetObject("Button1.Image"), System.Drawing.Bitmap) If I reselect the image and rebuild the project, the error goes away, at least for a while until it reoccurs after a later build.

The form does inherit from a form template class we have created, although the 50 or so other similar forms never experience this problem. Any assistance would be appreciated.

For controls that are bound, not all events are firing when the control loses focus. Specifically, the "Leave" event fires and thats it.

    - DataGrid KeyDown and MouseDown Events and AllowSorting Property I'm trying to implement a lookup function via the F2 key when pressed in data cells in selected columns of a DataGrid. I'm also trying to implement the same lookup function via a right-click of the mouse in a data cell of the DataGrid. I have KeyPreview set to True on the form. When anything is keyed into a cell, the form's KeyDown event does not fire nor does the DataGrid's KeyDown event fire. Is there something I'm missing or is there a workaround that doesn't involve a third-party data grid? If I right-click a cell in the DataGrid, the MouseDown event of the DataGrid does not fire. However, if I right- click the header line, the MouseDown event does fire. Is there something I'm missing here or is there a workaround? I've set AllowSorting to False in the designer for the DataGrid. In the form's Load routine, I customize the DataGrid and again attempt to set the AllowSorting property to False. The DataGrid still allows column sorting when a column in the header line is left-clicked. Is this property supposed to work or am I doing something wrong? Thanks. Chuck Tag: ErrorProvider Tag: 62873

    - Changing the look of the Invalid Property Value warning in a PropertyGrid? I know that this question has been batted around here for a while - and I know that sample code, using reflection and poking around inside the propertygrid class, has been posted by a kind soul.... but I'm really hoping that someone on the Forms team, or C# team at Microsoft can have a go at answering this. Q: When inside a property grid, I am throwing exceptions when a value is out of range for a cell. All works well - I get the "Invalid Property" box appearing... Except that the 'juicy' bit of my out-of-range warning is hiden by the "Details" button on the Invalid Property Value box that the grid shows... Is there any (semi-official) way of getting it to show a different box, or at least to have the 'Details' shown by default? Tag: ErrorProvider Tag: 62863

As we know every control has its own events and according to certain actions(by user, system etc.), corresponding event gets fired. I am trying to centralize the event handling to handle all events of the form and its containing controls in one procedure something like: Sub EventFired(source As Object, event As ???, args As EventArgs) ' source identifies the control say source.Name gives BtnOk, event should give the fired event, say BtnOk.Click o r just Click, args gives the arguments for the event ..... ..... code to identify the source of event, event type and event arguments and can control whether to let the event gets fired or cancel ..... If (condition1) Then args.Cancel = True ' cancels the event being fired End If End Sub Can this be done? If so how? Appreciate for the ideas, comments and solutions.

    - Use ComboBox to select Current Record in Databinding? I'd like to take this article a step further: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_vstechart/html/vbwlkcreatinglookuptableondata-boundwindowsform.asp I want to add another combobox to the bottom between PREVIOUS and NEXT. This Combobox will be bound to the Orders table and have a list of Order IDs. No problem. What I would like to do is, when an item is selected, change the current record for the form to be the one that was selected. (Just as PREVIOUS and NEXT move the current form's record to the previous/next orders.) It appears that I could do this by looking up the selection in the ComboBox on the SelectedItemChanged event and then matching the position and setting the position (much like behind the PREV/NEXT click events), however it seems that this should also be possible with data binding and no additional code. Is it? Thanks! Tag: ErrorProvider Tag: 62829

    - XMLTextReader hangs machine in forms load functions Microsoft .NET Team: I would like to report what I think is a bug in the XMLTextReader class. The bug can be reproduced in the following manner: 1) Create a C# Windows Application Project and add a form to it. Add System.XML to the namespaces of the project. 2) Add a ListBox control to the form, name it lbUsers 3) Add the following code to the OnLoad event of the form: protected override void OnLoad(EventArgs e) { XmlTextReader xmlConfigFile; string filename = Application.StartupPath + "\\test.vtx"; xmlConfigFile = new XmlTextReader(filename); while(xmlConfigFile.Read()) { if(xmlConfigFile.NodeType == XmlNodeType.Element) { if(xmlConfigFile.Name == "User") { if(xmlConfigFile.HasAttributes) { while(xmlConfigFile.MoveToNextAttribute()) { if(xmlConfigFile.Name == "Name") lbUsers.Items.Add (xmlConfigFile.Value); } } } } } lbUsers.Refresh(); base.OnLoad (e); } 4) Place the following XML File in the application directory for the project (the /debug directory). Name the file test.vtx <?xml version="1.0" encoding="UTF-8" ?> <ConfigData> <UserInfo> <Users> <User Name="AUDREY"> </User> <User Name="WESLEY"> </User> <User Name="DADDY"> </User> </Users> </UserInfo> </ConfigData> 5) DO NOT PLACE any breakpoints in the code. 6) Use the F5 key (Debug/Run) to execute the code. Result: The machine will hang. The only choice is the power switch. CTRL-ALT-DEL is ineffective. Other information: a) If you execute this code from a Button.Click event on the form, IT WORKS JUST FINE. b) If you comment out all of the code inside the while loop in the function, the machine will still hang. c) If you move the base class OnLoad above the while loop, the code will still hang. d) If you put this code in the OnActivate function of the form, the code will still hang. Please verify this bug, and suggest a workaround if possible. Thank you for your help. Walt Smith Vectiva.com Tag: ErrorProvider Tag: 62828

    - problem with report hi all, i'm using the "insertion model" of ADO.NET to see my reports. this model is the desconnected model of NET. i have to create a dataset object (visual dataset schema), base my report on it and after: a form with a crystalreportviewer, configure its property "reportSource" this method requires code which fills the dataset of our SQL's data and pass it to our report with the "setdatasource" method. i haven't any problem with one table but when i try it with several tables, it's imposible have you got any idea? thanks a lot for your interest here is my code: Private fbase As New fInformeBase() Private rpt As CrystalReport1 = New CrystalReport1() Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim conexion As New OleDb.OleDbConnection(gCadenaConexion) Dim sql As String = "SELECT AtributoPublicoObjetivo.* FROM PublicoObjetivo INNER JOIN AtributoPublicoObjetivo ON PublicoObjetivo.IDPublicoObjetivo = AtributoPublicoObjetivo.IDPublicoObjetivo WHERE (PublicoObjetivo.IDPlan)=" & gIdPlan Dim adapter As New OleDb.OleDbDataAdapter(sql, conexion) Dim dataset As New DataSet() adapter.Fill(dataset, "AtributoPublicoObjetivo") rpt.SetDataSource(dataset) fbase.CrystalReportViewer1.ReportSource = rpt fbase.CrystalReportViewer1.Zoom(75) fbase.StartPosition = FormStartPosition.Manual fbase.Location = New Point(0, 0) fbase.MdiParent = fPrincipal fbase.Show() end sub Tag: ErrorProvider Tag: 62824

Hey does anyone know of an example of using the error provider control using
a datasource/databindings that actually works? I've been trying for days to
get this and just can't seem to get it to work.

any help would be appreciated.

Thanks,
CJ
