    - Layered Window - Black Area Hi all, I have a form that I have turned into a layered window (the layered window is opaque). Everything works great except that if part of the form is covered and then uncovered, the uncovered area is black. I have tried doing an invalidate() but it does not update the layered window. Do I need to call an API function to update the layered window? Thanks, Cole Tag: How to save data to datasource on click on the pencil Tag: 89174

    - Dynamic Object Reference I have a menu form that has a number of buttons that each launch a different form. The syntax is the same except for the form name is different. How do create a common function that launches a new form that excepts the form name as an argument? My current syntax: Private Sub btnNewSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNewSearch.Click Dim applicantion As New applicantion applicantion.MdiParent = Me.MdiParent applicantion.Show() End Sub Private Sub btnDispute_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDispute.Click Dim dispute As New dispute dispute.MdiParent = Me.MdiParent dispute.Show() End Sub Private Sub btnClientAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClientAdd.Click Dim clientAdd As New clientAdd clientAdd.MdiParent = Me.MdiParent clientAdd.Show() End Sub I would like to create a VB function that works like this: Private Sub launchForm(ByVal formName as string) Dim form As New formName form .MdiParent = Me.MdiParent form .Show() Sub But the syntax wouldn't work because formName is not provided until Runtime. Any thoughts? Thanks. Tag: How to save data to datasource on click on the pencil Tag: 89167

    - How to keep a Child Form of a MDI Child contained I have an issue with a Child Form of a MDI Child staying contained within the Master Form. My first Form is called mdiMaster, which opens the mainMenu form with the following code: Dim MainMenu As New MainMenu MainMenu.MdiParent = Me MainMenu.Show() Then a button click event of the mainMenu opens an application form with the following code: Dim applicantion As New applicantion applicantion.MdiParent = Me.MdiParent applicantion.Show() The problem occurs when the application form tries to open another form, I have the following code: Dim searchForms As New SearchForms searchForms.MdiParent = Me.MdiParent searchForms.Show() The problem is that searchForms does not stay contained in the mdiMaster form. I tried the following syntax: searchForms.MdiParent = Me.MdiParent.MdiParent which caused a runtime error and hung the application. Also, I have the mdiMaster IsMdiContainer form property set to true. Any suggestions? Thanks. Tag: How to save data to datasource on click on the pencil Tag: 89166

We have all the necessary account and password, but the problem is when we need to confirm some data, the user have to leave his application go to the web site enter the password and read the result and then confirm the information. What I want to do is all the manual steps of getting to the web site and get the information at run time from the main application. The main application is a c# winform, I have some classes to get the response from a http but the page have a button and I don't know how to analyze what is happening. Is there a way to analyze what is doing when the user click the bottom from the web page, and of couse the way to simulate that action from the main application.

    - print button on printpreview dialog I just added a print and printpreview capability to my app. It's printing a nasty datagrid with hidden columns that may be filtered and sorted. Everything seems to work, but I'm having trouble with printing from the printpreview form. The preview looks right, I get the right number of pages, and the lines look right, but there is no text. Is there some trick to make this work? If not, how do I disable the print button from the stock printpreviewdialog. I can hear the users complaining about this already. Thanks, Mick.

    - winforms weirdness with context menu mouse up I'm seeing some weird business going on and I'm wondering if there's an easy workaround or if I have to go into hack mode. In non-winforms apps you must have a right mouse down followed by a right mouse up in order to get a context menu. One specific example is the tool bar which brings up the standard (Restore,Move,Size,Maximize,Close) context menu. However, it seems in winforms you only need a mouse up. Now in the control I'm creating I capture the mouse on mousedown and do seperate actions on mouse move depending on whether the right or left mouse buttons are depressed. But when I've pressed the right button, capturing the mouse, and then released over the toolbar(in order to release control) I get the context menu popping up. Oddly enough, after dismiss the context menu the mouseup event for my control fires. Obviously this is not the behavior I want. Seems weird the winforms team decided to raise context on mouseup alone. But fine. Do I have any options besides installing a message filter? Thanks in Advance, Robert Conde Tag: How to save data to datasource on click on the pencil Tag: 89144

    - ShowDialog, SEHException and Timer control I know the SEHException when calling ShowDialog is quite a common problem, generally associated with EnableVisualStyles, but I've just been having a problem with it, and I'd already added the DoEvents call before Application.Run, so it wasn't that. I'm working on an application which uses a timer to poll a database at regular intervals. There is also an override button to force an immediate check. When a dialog box was shown from the Timer control's Tick event, I got the SEHException, but when it was shown from the manual override, I didn't. Strange, thought I. As an experiment, I replaced the System.Windows.Forms.Timer control with a System.Timers.Timer object, and the problem went away. I post this in the hope that it might help others in the future.

    - VB.NET problems displaying custom dialog box I added a form to my project to use as a dialog box. The form is simple, 2 text boxes, 1 checkbox, 3 labels and 2 buttons. It will eventually allow a user to reset a password, but I haven't added the functionality yet. I have the dialog created when the user selects Tools - Reset Password from my main menu control. When Reset Password is clicked I execute: Dim frmResetPassword As New ResetPassword frmResetPassword.ShowDialog() Where ResetPassword is the name of the new form. When launched it's generating an error: Object reference not set to an instance of an object. The error is generated from an unknown module. Now here is where it gets weird. If I add a button to the form and run it again I don't get an error. I don't put code behind the button or change anything else (I still execute from the menu item), I just add it to the form. I have no idea what is going on and would be most appreciative to anyone who can point me to a solution. Thanks. Tag: How to save data to datasource on click on the pencil Tag: 89119

    - How to get rid of scrollbars in datagrid? I have windows form with datagrid control. I don't want the datagrid control to display vertical and horizontal scrollbars. I wonder whether there is a way to get rid of scrollbars without deriving my own class from System::Windows::Forms::DataGrid? The problem is that unless I derive my own class from DataGrid I don't have access to scroll bar objects. The HorizScrollBar and VertScrollBar properties of VertScrollBar are protected! Can anyone recommend alternative way to get rid of scrollbars? Thanks Tag: How to save data to datasource on click on the pencil Tag: 89118

    - PropertyChangedEvent I read this article called "Windows Forms Data Binding and Objects" by Rockford Lhotka wich in an MSDN article. It makes a custom class that can be bound to. If a value in the class changes from code or an other control it needs to be updated in all bound controls. ThatÂ´s where the PropertyChanged event comes in. The article says that de bindingmanager listens for those events. Now, the sample code (I didnÂ´t run it) is in VB.Net. I would like to do the same thing in C#. And guess what, it doesnÂ´t work. I donÂ´t know what i am doing wrong and canÂ´t find any samples. Anyone there that can give me a hint? Much appreciated, thanks. Tag: How to save data to datasource on click on the pencil Tag: 89112

    - ListBox component and underlying Items objects Hello, I've run into a brick wall in working with a standard ListBox. I'm loading lightweight objects into a ListBox component - call them Elements. The Element class has an ElementName property and an overridden ToString() method that displays the ElementName. When I load Elements into my list box Items collection, the ElementName displays and all is well. My problem occurs when I change an ElementName property programatically. The underlying Element does indeed change, but I can't get the text displayed the list box to reflect it! I can delete and re-add the Element and the change will show up, but neither ListBox.Update() nor ListBox.Refresh() change it. I've considered a custom draw method (which I may have to implement anyway). But is there another way of changing the text I'm overlooking? I'm not using data binding - can a ListBox programatically bind to its own Items collection? Any help appreciated. Thanks much Jim Stanley Media Services, Inc.

    - Is "colspan" in ListView possible? I am working with MS Visual studio C#.net, .net framework 1.1. Do you have an idea, how can I use the ListView (details display mode), that it does similarly as an html table do? Or there is a better container which would fit my needs? What I need in the ListView is: 1. Above some subitems, a common header should appear (above the actual column headers). 2. In some rows I don't have all details (texts for all subitems), but instead I have a commentary, common for some subitems. So, I would need a kind of "colspan" in a table. I would be grateful for any help/ Jola ---------------------------------------------------- I want to obtain that (example): <html> <table border=1> <tr> <th colspan='2'> </th> <th colspan='3'> Block 1 </th> <th> </th> <th colspan='3'> Block 2 </th> </tr> <tr> <th> Main item </th> <th> </th> <th> Subitem 1 </th> <th> Subitem 2 </th> <th> Subitem 3 </th> <th> </th> <th> Subitem 11 </th> <th> Subitem 22 </th> <th> Subitem 33 </th> </tr> <tr> <td> First entry </td> <td> </td> <td> 1284 </td> <td> 4352 </td> <td> 3214 </td> <td> </td> <td> 3421 </td> <td> 2412 </td> <td> 3421 </td> </tr> <tr> <td> Second entry </td> <td> </td> <td colspan='3'> here comes the commentary </td> <td> </td> <td> 4536 </td> <td> 9867 </td> <td> 3910 </td> </tr> <tr> <td> Third entry </td> <td> </td> <td> 3424 </td> <td> 3334 </td> <td> 3214 </td> <td> </td> <td colspan='3'> here comes the commentary </td> </tr> </table> </html> Tag: How to save data to datasource on click on the pencil Tag: 89104

    - How? Using a custom TypeConverter in custom grid column style. I have bound a grid column to an enumeration data type. I derive from DataGridTextBoxColumn and override GetColumnValueAtRow and call a function I wrote to convert the enumeration value to a descriptive text for display in the grid cell. This works well. Even though the grid is not editable, and the column is readonly, when one clicks on the cell I get a type conversion exception. Looking at the stack I see Edit calls GetText which uses an "EnumConverter" to convert the descriptive text to an int32, which ultimately tries to parse the descriptive as an int32, and of course fails. I see that DataGridTextBoxColumn has a PRIVATE type converter member. I am seeking any pointers to examples, or samples, or explanations of how to intercede the conversion of the descriptive back to an enumerated value for my custom column type. I think I need to implement a type converter, but I don't see how to tie it in. Or even just to know "it can't be done" would be helpful.

    - WinForms and AppDomains I have an application where I'd like to be able to run multiple instances of a Windows forms application. Due to a heavy hit in our application startup code it would be beneficial to be able to have a single process with multiple instances of the form. Additionally, it would be useful to be able to partition off each instance in it's own application domain. The current plan is for a module to handle starting a new thread which will fire up a new app domain and then load the form. This module will also handle firing up any new instances by creating a new thread and application domain. My concern is any issues surrounding the UI thread. I'm aware that only the thread that calls Application.Run should access any of the UI components. Typically you would only have one per process. In my situation I'll end up with multiple UI threads. However, each application domain will only have a single UI thread and only this thread will access any UI components. Is the application domain enough of a boundary for the UI threads or am I setting myself up for threading issues? Tag: How to save data to datasource on click on the pencil Tag: 89082

    - Change value in bound ctrl when value of another bound ctrl change I have been developing WinForms apps in .NET for several years and have never discovered a good solution to this newbish problem. I frequently encounter a situation where I want to change the value of a control when the user changes the value of some other control and both controls are bound to the same row in a DataTable. For example, say I have a combobox of statuses and a textbox for comments but comments are not applicable for certain statuses. When the user selects one of these statuses I want to set the text of the textbox to an empty string. So I add a handler to the combobox's SelectedValueChanged event and set the TextBox's Text property to an empty string. Doing this seems to cause unpredictable behavior. Sometimes I get an empty textbox but the combobox is changed back to its original value and other times the textbox is not cleared. I assume one change gets pushed to the dataset and triggers a refresh of the controls from the dataset but I'm not really sure. I have worked around this by clearing the textbox when the combobox loses focus but users are never happy with this solution. Having encountered this problem again I thought I would see if anyone can tell me the "right" way to do this. Tag: How to save data to datasource on click on the pencil Tag: 89071

    - Load a form Hello, I have created an application in vb.net. I want to show a chaild form on main mdi form. Since form contains many controls it is taking too long to get displayed completely and it also flickers. I have tried SuspendLayout and Resume Layout methods, but was not helpful. Can I load this form in memory and then show it(using form.show method) so that it will be displayed in lesser time? Will it help me? How can I load the form in memory without displaying it? Pls. reply soon. Thanks in advance. --RbanBph Tag: How to save data to datasource on click on the pencil Tag: 89039

    - 3 windows, bring all to front Hi All, This should be pretty easy, and I'm sure there's a simple way to do it, but it's eluding me. The application has three windows open at all times. Needed functionality: a click on any of the three windows should bring the other two to the front as well so that they would all be above any other program windows. I've been messing with BringToFront and the Activated event but everything I do seems to lead into infinite loops. Hopefully one of you knows the 'right' way to handle this common problem. Thanks for any help! - Tom Tag: How to save data to datasource on click on the pencil Tag: 89030

    - Win2k3 SP1 affects IEExec ?? Has anyone encountered issues running NTD apps on 2003 SP1? I have an application that runs fine when run from IE on 2003 SP0. It also runs fine when run from the file system (i.e., double-click the exe) on 2003 SP1. For some reason, when we run the same app from IE on 2003 SP1 machines, we're getting System.TypeInitialization exceptions in IEExec.exe . When examined closer by building the app with debug symbols on the server, it appears that (at least in this case) the TypeInitializationException is being caused by an exception as a Web Proxy Class (for a web service) is being initialized. The Message is "The type initializer for "System.Xml.Serialization.Compiler" threw an exception. The stack trace begins: at System.Xml.Serialization.TempAssembly.GenerateAssembly(XmlMapping[] xmlMappings, Type[] types, String defaultNamespace, Evidence evidence, CompilerParameters parameters, Assembly assembly, Hashtable assemblies) at System.Xml.Serialization.TempAssembly..ctor(XmlMapping[] xmlMappings, Type[] types, String defaultNamespace, String location, Evidence evidence) at System.Xml.Serialization.XmlSerializer.FromMappings(XmlMapping[] mappings, Type type) at System.Web.Services.Protocols.SoapClientType..ctor(Type type) at System.Web.Services.Protocols.SoapHttpClientProtocol..ctor() Has anyone seen behavior like this? Please post if further info would be helpful. Thanks in advance. Tag: How to save data to datasource on click on the pencil Tag: 89027

    - No Touch Deployment using HTTPS? 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!

    - 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!

Hello,

I'm trying to allow saving data to datasource when user clicks on the
"edited" pencil.

The pencil is automatically shown by the datagrid when given row is edited
and it is hidden when user clicks on it, so it looks like an obvious why to
trigger saving modified data.

But how to do that?

I've tried to catch RowChanged event of appropriate DataTable, but it is
lauched after user leaves the row, which is too late.

Any hints?
