    - Problem / Bug?: MDI child forms looses MouseLeave events after visibility changed Hello, I have the following problem (bug?): I have one MDI form which contains one Child form. On the child form there is one textbox. The textbox has two eventhandlers: - MouseEnter (set the background color to red) - MouseLeave (set the background color back to white) The MDI form shows upon startup the Childform and contains two button - button1: shows the ChildForm - button2: hides the childform The problem: When the application starts, the child form is show and the two events on the textbox are working perfectly: when you move the mouse over the textbox it turns red; when you move the mouse away from the textbox it turns white. Clicking on the buttons of the MDI forms hides/shows the childform. BUT after the child form was hidden and shown again, the event MouseLeave is not execute! when you move the mouse over the textbox it turns red; when you move the mouse away from the textbox NOTHING happens! Why? What do I do wrong? Is this a bug? All suggestions, information welcome! Robbie De Sutter The sourcecode to repeat the problem [in VB.NET]: Code for the MDIForm (MDI form with two buttons) Public Class Form1 Inherits System.Windows.Forms.Form Private theChild As child Public Sub New() MyBase.New() 'This call is required by the Windows Form Designer. InitializeComponent() 'Add any initialization after the InitializeComponent() call theChild = New child theChild.MdiParent = Me theChild.Show() End Sub [...] Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click theChild.Show() 'theChild.Visible = True '> NO SOLLUTION End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click theChild.Hide() 'theChild.Visible = False '> NO SOLLUTION End Sub End Class Code for the ChildForm (normal Form with an TextBox) Private Sub TextBox1_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.MouseEnter TextBox1.BackColor = Color.Red End Sub Private Sub TextBox1_MouseLeave(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.MouseLeave TextBox1.BackColor = Color.White End Sub Tag: Remove/restore columns in datagrid Tag: 59804

    - Custom UITypeEditor for Color won't work... Is there anything special with the Color type or any other value type for that matter? I designed a custom color picker and apply it to a property like this: [Editor(typeof(myColorEditor), typeof(UITypeEditor))] public Color SelectedColor { get {return this.selectedColor;} set {this.selectedColor=value;} } and my editor is totally ignored. The default editor is opened... Why?? Thank you!! Tag: Remove/restore columns in datagrid Tag: 59792

    - Multiple instances of an application I have a .NET application that does data processing by state (disconnected). The state to process is determined by a command-line parameter. When I run multiple instances of the application (which I need to be able to do), the processing is handled fine. However, all instances after the first one GPF when they complete their processing and attempt to close. Also -- I don't know if it is related, but the event log contains this message for each app that GPF's: "Installing the performance counter strings for .NETFramework failed. The Error code is DWORD 0 of the Record Data." Thanks for the input. Russ Bishop MCSD Tag: Remove/restore columns in datagrid Tag: 59770

    - ListView Problem I'm having a rather tedious problem with the listview control in visual basic.net I am trying to achive two simple procedures, I thought :) 1. I have only one column populated but still there is an extra empty column listed to the right of the header. Is there no way to specify that I only want a single column. Or is there a way to hide that unpopulated extra column that I don't want. 2. How exactly does one reference the text or value of the selected sub item. I would like to pass this text in my case to a function but I'm unable to get it. Sorry for the I'm sure simple questions, but I have googled my brains out and been over the docs and can find nothing to point me in the right direction.

    - Very basic question - where to store data for a Windows app? I'm new to Windows Forms development (web-based development is my primary area of focus). I've been tasked to create a windows application that basically provided users the ability to take surveys - kinda like a telemarketing-based survey application. My question is this: what is the best mechanism for storing the data that users enter into the application? The options, that I'm aware of are: 1. MSDE (SQL Server Desktop Edition) 2. JET (MS Access-based database file) 3. XML 4. Serialized objects I'm unable to use a standard client/server approach here, as the application is considered "sometimes connected" - network access will not always be available. So, the app will have to temporily store the data locally until a network connection is found. I'm looking for input on the pros/cons for the approaches listed above and for any other options that are availabe. Also, pointers to online resources in this area would be greatly appreciated.

    - Missing Events in C# I am learning C# for the Compact Framework. I put a PictureBox on a form. But when I click on the events button(on the Properties Tab), only ParentChanged, Validated and Validating are listed. There is no click event. But if I manually code for a Click event, it works. I added this line after the call to InitializeComponent() this.pictureBox1.Click += new System.EventHandler(this.pictureBox1_Click); This works but I am curious as why it is not listed on the properties tab (its documented as a valid event) Thanks Srinivas Tag: Remove/restore columns in datagrid Tag: 59758

    - save Excel with a windows form I have a windows form that traps an "before save" event in Excel 2000. What I would like to do is save the Excel in SQL Server by calling a web service. I thought I could have serialized Excel and send it to the web service as a string for database storage, but it seems that Excel cannot be serialized. This windows form will be a no touch deployment application so any extra software would be difficult. Any ideas? Thanks, Shane Tag: Remove/restore columns in datagrid Tag: 59755

    - Updating a Windows DataGrid - with a stored proc. which has multiple joins Hello Everyone, I have a datagrid which is built based on a combobox.Text input. The data is coming from a stored procedure which has several joins ,to make the info more readable. However, I am only interested in editing fields in the table supplied by the combobox.Text. From what I have read you can use the command builder -- ONLY-- if you are selecting from one table. Is that correct? Is there a way to tell .NET Framework which table is the primary table and can be edited? Thank You in advance for Your Help, Ken Tag: Remove/restore columns in datagrid Tag: 59750

    - Application.run issue I have an application that I do NOT want the form to be visible as this is a background application. I set the forms Visible property to false in the forms constructor. The application places an icon in the System Tray that has a menu to show the form if the user wishes to see it. I'm displaying the form by calling Application.Run ( form ). This forces the form to be visible. I overrode the OnVisibleChanged event in the form and it is called immedialely after the Application.Run call. Does anyone know a way to keep the form hidden?

    - DataBinding could not find a row in the list ... ? I get the following exception message when I try to reopn a form window after closing it down (while the main MDI window is still running) "An unhandled exception of type 'System.Exception' occurred in system.windows.forms.dll Additional information: DataBinding could not find a row in the list that is suitable for all bindings" This message goes away when I unbind the datagrid object on the form from the datasource & datamember. This datagrid is bind to the Details DataRelation. whereas rest of the form is bind to the Master DataTable. Both the master and the DetailRelation table are in the same dataset. there is nothing fancy about the datagrid object it shows int type fields only and no checkbox or textboxes in it.

    - PropertyGrid Contol localized DisplayName I'm Using the PropertyGrid Contol , and have a requirement to display a localized property name. Therefore My Classes Implement ICustomTypeDescriptor, and return a custom PropertyDescriptor Collection, The issues is that in the Derived PropertyDescriptor object when overriding the "DisplayName" property it causes the PropertyGrid to call the "DisplayName" Property an inordinate number of times, which then makes the PropertyGrid, very slow and unusable. code Snippet ICustomTypeDescriptor. public PropertyDescriptorCollection GetProperties(Attribute[] attributes) { .Returns new PropertyDescriptorCollection containing MyPropertyDescriptor objects } public class MyPropertyDescriptor : PropertyDescriptor public override string DisplayName { get{return "Overriden DisplayName"} } Worth mentioning, if I comment out the DisplayName Override Property And run the code, then the grid functions as usual? Any one have any idea's why DisplayName gets called again and again, and how to prevent it? Cheers Brett Tag: Remove/restore columns in datagrid Tag: 59742

    - Image serialization (not solved)... Here I come again with this question. I posted this in many forums and nobody gave an answer. Maybe there is no answer? So here goes: I use a custom CodeDomSerializer to add serialization to some members of a colection member of a custom control. One of these members is an Image Type. I use SerializeResource to actualy store the image and SerializeToExpression to create the deserialization code. It all works out fine *as long as* the ResourceManager object (resources) is already created on the parent form. This is the same object that gets created when you change the backgroundImage of the form. I did some reflection in the assemblies and I found out an internal class called SerializeResourceManager that seems to be doing this job (of checking if the ResourceManager object exists and if not create it). So the question is, from inside the CodeDomSerializer of a custom control, how can I access and check if the ResourceManager object exists as a member of the parent form and if not to create it? Do I need to access the DesignerHost? Anybody has any idea? Thank you!! Tag: Remove/restore columns in datagrid Tag: 59738

    - Windows message queue question Hi all! I'm writing a windows application, that contains a control that shows a bitmap. The bitmap is painted in the controls OnPaint method, using the Graphics.DrawImage method. It is possible to drag the bitmap around inside the control, using the mouse. While dragging the image, I call the controls' Invalidate method every time i get a MouseMove-event. So far so good. The problem is, that, when the image is large and I drag it around and then stop moving the mouse, the image often still keeps moving over the control for a few more seconds. I guess, this is caused by MouseMove events, still contained in the applications message queue. A profiling utility showed, that OnPaint was called exactly as often as MouseMove. I was surprised about that, since I thought that OnPaint would be called asynchronously and only when there is time for. Can anybody explain this to me? How can it happen, that there are MouseMove events in the queue for such a long time and why is OnPaint obviously called every single time, Invalidate is called? (I don't call Update!) Is there a possibility, to drop all MouseMove and Paint events, currently contained in the message queue, except the last ones? Does anyone know another solution for the problem? If this is the wrong NG for my question, wher else should I post it? Thanks for any comments Markus Tag: Remove/restore columns in datagrid Tag: 59719

    - User authentication in Web Service calls from a remote NTD app I am developing a Windows Forms application that makes requests to a web service and in return receives configuration data that is user specific, i.e. based on the user's window's authenication on the server side domain. My problem is that I am unaware as to how I should configure the app so that when it calls into the web service, the web server will be able to identify the user. Initially the application will be running on the same domain either over a LAN or though a VPN connection although it is anticipated that in the future connections may be made from a m/c outside this remit although the latter scenario does not have a high priority right now.

    - Cannot remove windows form from .net project I had a windows form named "FormOrdersList" that I deleted from the .net project. During the deletion i was asked wether I wanted to update something on the very same form (I dont remember what it was) and I just clicked "yes" which I believed to be the default. Then I tried to add an inherited form with the name "FormOrdersList". I get the response that FormsOrderList cannot be added because it exists in the project from before. I then try to add a normal (not inherited) windows form named "FormOrdersList". This works fine as well as deletion. But when I try to add "FormOrdersList" as inherited form again I get the respons that the form exists in the project and cannot be added.

    - Passing parameter to Smart Client application Hi I am creating a smart client application. The requirement is as such....An asp page gets loaded.(NOTE: an asp page gets loaded not aspx page). This page is actually a search page in which the user enters some input in a textbox. On the basis of the value entered, some results are displayed in form of links.On clicking the link, i want to call a smart client application by passing in some parameter that is returned along with the serach results. What i am doing is on clicking the resulted link, i am calling an aspx page.(NOTE: i am loading an aspx page. not asp page). Which in turn calls the smart client application. But the issue is that i am not able to pass the parameter to the exe. I need to do this because my smart client application does something on the basis of this parameter. Does anyone has any idea on how to pass parameter to the exe from the aspx page and how to use the parameter inside the exe. Thanks Suvendu Tag: Remove/restore columns in datagrid Tag: 59705

DataGridColumnStyle in vb.net. It let me with a doubt. Isn't the framework
that defines if a class is MustInherit or not? Why does C# and vb.net
differs when working with this class?

TIA,
Erik Cruz
