    - why aren't changes in datasets recognized for bound controls? Hi, I've got a simple VB/Access app that binds text controls to various fields in a database table. Everything works fine, EXCEPT that when I call the Update method on the data adapter, nothing updates, because it thinks nothing has changed! If I make changes to the fields thru the bound edit boxes, and then check the "HasChanges" method on the dataset, it runs FALSE - even though the changes ARE reflected in the dataset's data! How do I fix this??? The Update calls do nothing even if I edit all the fields because the dataset won't recognized that anything has changed. The updates and everything work fine if I manually set new values into the fields; the update works and HasChanges returns true. ex.:dataset.tables(0).rows(0)("my field") = foo thanks!

    - How to track changes in a datagrid I'm developing a desktop app that displays several screens of of data in a two column fashion, the left column has the tiles and the right column has the input controls (textboxes, dropdowns, etc) for input. Typically the app is used to display preexisting data and the user would edit certain things. The data is saved on a network drive and can be edited by many users who have access to the drive (no concurrenct editing) so it needs to be able to track who changed what when. If a value is changed 10 times by 10 different user, it should be able to keep the history. I'm thinking maybe a DataGrid control is the best choice for displaying and accepting user input but not sure how it captures the change info. Could anyone point me in the right direction?

    - variable height TreeNodes in TreeView Is it possible to create a TreeView with variable height TreeNodes? For example, I may want to have text in a given tree node have hard return characters that wrap that node's text to next line? There is the TreeView.ItemHeight property but that only allows setting a height for all TreeNodes in the TreeView's underlying tree model (which is limited to TreeNode types of trees).

    - Cursor "stuck" In Databound Control/Caching? I am having a strange issue and cannot solve it. Basically, I have a form that edits information in a database. This form has many different controls that are bound to a business object. When I first load the form to edit the info everything works properly. The process of loading the object also loads the object into cache (Isolated storage using Enterprise Library 2.0 caching application block). If I load the form again and attempt to edit a field (say notes a textbox) my cursor gets "stuck" in the text box and I cannot click on any other control in the form. However I can close the form with the X in the upper right corner and the keys still function properly (Enter saves the object and Esc closes the form). I have looked the stack trace but it is giving me nothing. I have no idea where to begin. Has anyone seen something similar or have any ideas what it might be? Any ideas how I can go about getting some info to solve the problem? Tag: No Touch Deployment using HTTPS? Tag: 89013

    - Form Display Hello, I have designed a form in vb.net. I have placed a tab control with 3 tab pages on the form. This tab control holds many controls in each tab page. This form is MDIChild form. I have not written much code on the form. Whenever I run the project, form is dipslayed as textboxes first then Data grid followed by another tab on the form and so on. Form does not display all the controls at once as complete form. What I should do in order to avoid this? Early response is awaited.. -RbanBph Tag: No Touch Deployment using HTTPS? Tag: 89010

I got some problem with the key events, they doesn't rise. first I made a new win project in C#, and I set this.KeyPreview = true; also this.KeyUp += new System.Windows.Forms.KeyEventHandler(this.fClient_KeyUp); and then I test run the app, and the keyup event did evoke. then I added a brower control into the form private AxSHDocVw.AxWebBrowser mviewer; and test run the app again, but this time the keyup didn't evoke, I assume the the browser control took the key events, how do I let the parent form evoke the key events again? and the browser control seems don't have any key event handler, am i right? any help would be greatful. regards Steve p Tag: No Touch Deployment using HTTPS?

    - Custom Designer Hi, I'm writing a control called a validating submit button. Basically, you can tell it to validate a number of controls when the user hits this button. When they hit the button, it'll say, "You must enter yada yada..." and highlight the bad field. Ok, now that I've got that out of the way, I think this problem should be relatively easy. Basically, I created a special designer that was a form that had two lists, one of available controls, and one of controls it will validate, in order. It would then add these items an arraylist of the inherited button class. This seems to work fine! I can run my custom verb, have it open up and show all the items that are currently selected to be validated and all of that jazz, but it doesn't change the actual .vb file in the InitializeComponent sub of the test form. So basically, it can change all these values on the design-time copy of the actual control, but I can't figure out how to add code to the initialize component of the form that'll be using this control. I figure that this question ought to be rather easy, as being able to create a custom designer without being able to "save your changes," so to speak, is pretty useless, and probably a commonly asked question.

    - Sometimes clicking on a TreeView node doesn't select it Hi; I have this case where when I click on a line in my TreeView, it selects it for a second, and then moves the selection back to the previous selection. Usually I have to click 3 times to get it to stick - then it's fine from then on. The tree is not set to accept drag/drop. HideSelection=false, otherwaise all is standard. This is the only event I have for the control - and it is the only control in the form: private void Tree_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e) { TreeNode node = treeDB.GetNodeAt(e.X, e.Y); if (node == null) return; RootNode root = node.Tag as RootNode; if (root == null) return; DoDragDrop(new DragDropData(app, root), DragDropEffects.Copy); } Any ideas? -- thanks - dave Tag: No Touch Deployment using HTTPS?

    - GUI from code Back in February I asked if anyone knew of a code-based presentation layer / layout manager. There are two: MyXAML (http://www.myxaml.com) lets you instantiate components such as forms and controls through markup rather than code. It uses an XML markup language (though not Longhorn's MSAvalon). MyXAML is open source. CoderForm (http://www.fivetuple.com) takes a different approach by keeping the UI spec within code, but wrapping the UI classes (Forms, controls etc) to make it easy to define the interface from code). Take your pick. Tag: No Touch Deployment using HTTPS? Tag: 88982

    - DragEventArgs and GetDataPresent with abstract base class Hello: I am trying to build a drag-and-drop operation with a control derived from my abstract base class. The control is either a PictureControl or a PictureGroupControl, both of which have PictureComponentControl as their superclass. When handling a DragOver event, I'd like to treat the dragged object as a PictureComponentControl without having to explicity test for whether the object is a PictureControl OR a PictureGroupControl, but GetData/GetFormats/GetDataPresent seem to only work with the subclass, not with the superclass. I've even tried explicitly casting the object when I begin the DoDragDrop() operation, but even then it doesn't seem to stick. Any advice for me? I know I could test for both subclasses explicitly, but that seems like bad OO -- then, in the future when I invent a SuperPictureControl, I'll have trouble. Is there a better way to do this, perhaps using Reflection or an Interface? Thank you, /m Tag: No Touch Deployment using HTTPS? Tag: 88958

    - Validation of data in win forms 2.0, Insert I am developing an application that requires the user to add and or change data. The application will be coded in winforms using .net 2.0. I am struggling a bit to understand how to implement validation of the data. A simple example is a table the has Description and Remarkscolumn. The Description is a required field. It must be non blank. I have implemented a dataset for this table and have implemented validation in the OnColumnChanging event in the datasets partial class. I have wired this into an errorprovider component on the winform. THis works as I expected on an update. The validation logic successfully finds the blank column and stops the user from entering a blank value. An insert does not work as I expected. The OnColumnChanging event does not seem to get fired on an insert. Any help would be appreciated. Tag: No Touch Deployment using HTTPS? Tag: 88955

    - Event Log? Hi all, I've written a window service which needs to write to the event log from time to time based on certain events. Apart from a minor issue at the moment where the actual log isn't created and it uses the "Application" one, I always get the following: "For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp." added to the bottom of each of my "information" type event log entries. As you are aware there are the following types: Error FailureAudit Information SuccessAudit Warning Does anyone know of any way to either turn off that line from the log entry, or, add my own 'types' to the event log types so that I can use my own "RobsInformation" for example as a type that doesn't display that surpurflous link.... Any information would be really appreciated. I have other applications (obviously), installed on my PC, and things like Norton AV write to the event log with "information" type entries, but they dont have URL's back to MS. In an ideal scenario here I'd be able to add my own URL pointing to a web page that gives details of the error message (as MS do). Thanks in advance for any help.

    - Problems editing datagrid bound to altered datatable I have loaded a DataTable from SQL server table via SQLDataAdapter as a basis. Once filled, I add columns that are calculated, and found via other methods. This includes tooltip text specific to the row, row foreground and background colors, and data parsed from text files on disk. And even artificial rows to indicate to the user where there are missing database records. I bind the datasource/datatable to a DataGrid. The display comes up fine. I try to edit some cell, expecting it to ONLY update the in-memory dataset/datatable, and I get this message box when run outside the IDE: Error when committing the row to the original data store. Object reference not set to an instance of an object. Do you want to corret the value? [yes] [no] BTW - When run in the IDE in DEBUG It merely throws an exception, shows 3 threads, each with no call stack. I have to run without the debugger in order to get this message box which at least gives some clues I don't understand, rather than no clues at all. Is this because of the extra columns and/or extra rows I may have added SINCE the fill? I observe it happens REGARDLESS of adding extra rows. If so, does this mean I must create my own IList for binding, or such, or is there some way of ferreting out the cause for the error. Also, I notice I get errors of this nature when trying to enter invalid dates, for example. I need to take control of the data posting. I will be responsible for programmatically updating SQL when the user is done. Anything you can point me to to get my head wrapped around this would be greatly appreciated. I would like to take more control of cell data validation. Tag: No Touch Deployment using HTTPS? Tag: 88926

    - Process.Start() and winword Hi all, I launch documents (whatever extension) with the following code: System.Diagnostics.ProcessStartInfo startInfo = new ProcessStartInfo(attachmentFilePath); editAttachmentProcess = Process.Start(startInfo); This works fine for a number of document types/applications. However, if the file is a .doc and Word is launched, the "process" variable gets a value only if Word was not running already because Word will open documents in an existing instance. The problem is that the variable "editAttachmentProcess" is null when launching a .doc and Word was running already. I wish to manipulate the Process (e.g. attaching an event handler to .Exited etc.) - what is the best way to get the process that the document was opened in, given that a new instance might not have actually started? I thought of the following approach: 1) Get the application that is associated with the extension via Win32 calls 2) Cycle through all the processes (Process.GetProcesses), then cycle through each open window in the process to see if document is open therein. Any other ideas/suggestions? Regards Joubert Tag: No Touch Deployment using HTTPS? Tag: 88921

    - Apply a theme to a dot net application Hi, I want to know if it is possible to apply a custom made skin/xp theme to an individual dot net application. What I am trying to do is create a new skin\xp theme (e.g. Different style scroll bars) and then get my dot net application to use this. This way no other applications are compromised. Does anyone know if this is possible and if so how? Thanks Glen Tag: No Touch Deployment using HTTPS? Tag: 88918

    - Get Windows icons for files in a ListView? Let's say I know a file extension and I want to get the Windows icon for that type of file, and put that icon in the image for an item in a list view. Would this be possible without loading all possible Windows icons into the image list at compile time? In other words, is there a way to dynamically put in the image for a list view item at runtime, and get it from Windows based on the extension type? Tag: No Touch Deployment using HTTPS? Tag: 88917

    - Having trouble with simple data binding Hello, I have two labels, call them leftLabel and rightLabel, that start off next to each other. leftLabel has its autosize property set to true. What I am trying to do is bind rightLabel.Left to leftLabel.Right so that whenver the autosizing label changes size due to longer text, the right label will always be drawn right after it. I started an empty form and added the two labels. Then I have in the constructor: public Form1() { InitializeComponent(); rightLabel.DataBindings.Add("Left",leftLabel,"Right"); } I also have a textbox and in its text changed event I just set leftLabel's text to whatever is in the text box. The thing is, eventhough leftLabel changes size, and its Right property is changed, rightLabel does not move. What am I doing wrong? Thanks, -Flack Tag: No Touch Deployment using HTTPS? Tag: 88913

    - Problem with advanced Master-Detail grids Okay, I'm having an issue I'm hoping you can help me with. I have two datagrids in a Master-Detail relationship. The top is vehicles, the bottom is a mileage log. The mileage log should only show the entries for the vehicle selected in the vehicles grid. Here's the standard way that I keep finding to set up this scenario: 1) add a relationship to the DataSet, 2) set the master grid's DataSource to the DataSet, and set it's DataMember to the master table in the dataset 3) set the detail grid's DataSource to the DataSet, and set it's DataMember to the relationship Voila, supposedly. The problem is, I can't let people add records to the master grid using the append row. Instead, I have Add, Edit, and Delete buttons that do the appropriate action through a different form. To disable the Append row, you have to create a DataView for your master grid and set it's AllowAddNew property to false. Fine, but if my master grid is bound to the DataView instead of directly to the dataset, it gets it's own CurrencyManager, which means the detail grid won't stay syncronized with the selection in the master grid. To get around this, I've hooked into the PositionChanged event of the DataView that controls my master form. In that event handler, I set the RowFilter property of the DataView to which my detail form is bound. That filters the visible rows down to the ones matching the selected record in the master grid. This solution creates another problem, though, because now when I add a detail row using the DataGrid's append row, it doesn't have any knowledge of the relationship, so it doesn't fill in the parent ID correctly. I'm getting around this problem by hooking in to the ColumnChanged event of the DataTable that represents the detail table. That code looks like this (remember that GasMileageLog is the detail table, and Vehicles is the parent table): private void GasMileageLog_ColumnChanged(object sender, DataColumnChangeEventArgs e) { DSMileage.GasMileageLogRow row = (DSMileage.GasMileageLogRow)e.Row; DataColumn col = e.Column; // set VehicleID to the currently selected vehicle if it is unset if ( row.IsVehicleIDNull() ) { CurrencyManager cm = (CurrencyManager)BindingContext[dvVehicles]; DSMileage.VehiclesRow vrow = (DSMileage.VehiclesRow)((DataRowView)cm.Current).Row; row.VehicleID = vrow.VehicleID; } } Now, this almost works. It's so close I can taste it. But there's one more problem. Remember how I said you modify records in the master table with Add, Edit, and Delete buttons? Well, if you use the Add button to add a new record into the master table, the ID that .NET generates for it isn't the actual ID that gets written into the database. This is good, because .NET doesn't know what IDs are actually in the database, and we don't want it to cause collisions. But it's bad, because when I try to use the above code to write a new detail record that should be related to a master record that hasn't been written into the database, the detail records end up associated with nothing once everything is saved to the database with the adapter.Update() method. Granted, I could get rid of my problem entirely by having the Add button save directly to the database. But so far, the whole thing is playing nicely with disconnected datasets, so I have cancel buttons that abandon all the changes up to now, including any new master records and any changes or additions to the detail records. I'd really like to keep it that way if at all possible. And this has got to be possible. I'm open to alternate approaches. If I need to go back to using the relationship instead of syncing the detail records to the master records manually, that's fine, but I will need to know how to turn off the append row without using a dataview. Either that, or I'll need to know how to hook a dataview up to a relationship. So far, I haven't found a way to do either of those things. Any ideas?

    - App Architecture question ? Hello, Iam starting on an application for an heat exchanger design. At the core, is a numerical solver that takes the HXInput instance and returns an HXResults instance. HXInputs is as follows : class HXInput { private HXAir mAir; private HXFin mFin; ...... // and so on. } Each of those HXAir and HXFin classes are huge, and contain info of the order of double [200, 200] Current design : # 1 SDI main form, that shows some info from HXInputs # 1 UI process controller that holds an instance of HXInputs, and the solver. The SDI form has an instance of UIP and sends menu commands to the UIP. Then the UIP shows different forms for editing information in HXInputs. # N different dialogs to display/edit different information in HXInputs and also a Tab page on SDI with results to show after the simulation is run. Heres the twist - There are dependencies between the data shown by different forms. Meaning - if one forms changes something in HXInputs, that affects some other UI options on other forms, or they need to be reflected on the main SDI window. What kind of architecture/pattern should be used for this app ? Iam looking for something that would allow easy addition of new data in HXInputs. I understand that this is too complex to explain, without figures, but would very much appreciate any advice. thank you. vikrantca Tag: No Touch Deployment using HTTPS? Tag: 88909

I have two classes. one inherit from 'TreeView' and the other from 'TreeNode'. In 'MyTreeView' i override 'Nodes' (keyword- new) in order to open my custom editor. In public partial class MyTreeView : TreeView, I use the next statement: [ DesignerSerializationVisibility(DesignerSerializationVisibility.Content), Editor(typeof(NodesTypeEditor), typeof(UITypeEditor)), ] new public TreeNodeCollection Nodes { get { return base.Nodes; } set { TreeNode[] myTreeNodeArray = new TreeNode[((TreeNodeCollection)value).Count]; ((TreeNodeCollection)value).CopyTo(myTreeNodeArray, 0); ((TreeNodeCollection)value).Clear(); this.Nodes.AddRange(myTreeNodeArray); } } but the DesignerSerializationVisibility create the next code, which produce casting error on run time: MyCheckTreeNode myCheckTreeNode1 = ((MyCheckTreeNode)(new TreeNode("TreeNode"))); I need it to be : MyCheckTreeNode myCheckTreeNode1 = new MyCheckTreeNode("TreeNode"); In the editor i use TreeView and PropertyGrid. the code in 'Add CheckBox Node' is: treeView1.Nodes.Add(new MyCheckTreeNode("TreeNode")); How can i fix it???

Hi,

I am trying to use NTD with HTTPS and get this error: "An execption
'System.Security.SecurityException' has occurred in IEExec.exe". I must
access this exe through a https site. Is there a way to make this work?

Also - I put the Application.exe in the Virtual Directory to use NTD. Do I
also put the Application.exe.config in that directory as well? I haven't been
able to find many detailed examples on how to use NTD.

thanks in advance!
Bill
