    - ActiveX can't create object Hey, I hope that this is the right group to post my problem. I have a program (VB.NET) that uses a dll. The program runs perfectly. So I decide to test the program on a server without visual studio. But on the new pc I alway get the error "ActiveX can't create object". I have no idea anymore what to do to solve this (tried severel answers found on the internet, but not one of them helped). This is what I do: Dim net27 as new Net27APIContainer() That work fine on the other pc. But the following gives me the error: net27.connected = true Can someone help me, step by step, to check what can create this problem? Thanks a lot in advance!

    - Hide() not working correctly Hi, My application should only ever display one form at a time. To achieve this I navigate between forms using the following logic: From formA to formB - formB.Show() formA.Hide() This is fine and works OK except in the following case: If the form to be displayed (formB) takes a few seconds to load, and in that time the user clicks on the current form (formA) IN THE TASKBAR, the system displays formB but does not hide formA. Both of the forms are displayed in the taskbar, and both can be selected by clicking or Alt+Tabbing. I have put some debug in, and the form being hidden does get the message, and it even thinks it has been hidden (if your query the Visible property it is set to False, even though it clearly IS visible). This is becoming a real pain and I have not yet found a suitab;e workaround. Can anyone help? Thanks for any help. Tag: GridLines in DataGrid Header Tag: 59871

    - ComboBox: After setting DataSource no Items Hi, after setting the DataSource of a combobox mycombo.DataSource = myStringArray; (for example in the load event method of the form) it is not possible the set the selected item. Setting the default value like mycombo.Text = myStringArray[2]; or mycombo.SelectedIndex = 2; or mycombo.SelectedText = myStringArray[2]; doesn't work. This is because mycombo.Items.Count = 0. At what time will the items be filled ? Is there a possibility to fill the items after setting the datasource ? Thanks, Kai Tag: GridLines in DataGrid Header Tag: 59866

    - Toolbar flat style and double buffering Hi, The application I'm writing requires double buffering it also requires a toolbar with its appearance set to flat. However, this causes a problem because when you set the following control styles: SetStyle(ControlStyles.DoubleBuffer, true); SetStyle(ControlStyles.AllPaintingInWmPaint, true); SetStyle(ControlStyles.UserPaint,true); I've looked into this and It think its because of the WM_ERASEBKG not being called, has anyone got a fix for this, I don't know how to manually send this message and at what time?

    - Lost/Gotfocus combobox Hi, I have a bizarre effect on my winform. I have a databound combobox. The focus on my form is on another control. When I click on the combobox with the mouse, the gotfocus event is fired. So far so good. But when I use the <Tab> button, first the lostfocus and then the gotfocus event of the combobox is fired. Is this normal and how to fix it? Thanks Kurt Vandevelde Tag: GridLines in DataGrid Header Tag: 59855

    - Implementation of RadioButton Hi, I'm implementing a component that is similar in functionality to RadioButton. Basically it's a RadioButton with a different visual representation and it allows the developer to pick a maximum number of simultaneously selected buttons. (So instead of just allowing 1 of n buttons to be checked, you can allow 2 of n buttons to be checked, etc.) My question isn't really about how to implement that kind of control. Rather, I'm curious to know how RadioButton "know" to uncheck themselves when another RadioButton in the same group is checked. Does each RadioButton just go through the Parent.Controls collection when it is checked? Maybe something like this? RadioButton rb; foreach (Control c in this.Parent.Controls) if (typeof(c) == typeof(this)) { rb = (RadioButton)(c); if (rb.Checked) rb.Checked = false; } Seems like there should be a better way to do this.. Would this get slow if the Parent.Controls collection were large? Thanks in advance, Baldeep Tag: GridLines in DataGrid Header Tag: 59850

    - Validating event I have a form which contains a TextBox, and a 'submit' button which print TextBox.Text to console I added validating eventhandler to check if the Textbox is empty and set the errorprovider if it is empty and set CancelEventArgs.Cancel = true to make sure the user input something however..it seems that the validating event only raised when the textbox is in focus then lost focus so if I show the form and click the 'submit' button immediately, the validatin event will not be raised which means that I cannot make sure the user entered something to the TextBox... are there any methods to rise the validating event to the textbox or there are better ways to handle this? thx!

    - Finding Nested Control's Parent Form? Call me a fool but I couldn't find a way to find the form that was ultimately the parent of a control when the control itself was nested. I one case, I created an inherited Panel class. In it I needed to make reference to the parent form and subscribe to its events. Unfortunately using the control.Parent property only works if the control is directly pasted onto the form. If my panel is nested inside of other panels/controls, this isn't so easy. As such I wrote a class called ParentFormFinder. (below) Unfortunately, it is rather intensive and it seems a waste of processing power. Am I missing some easier approach? Since I have apparently been having memory leak issues in .NET I am beginning to investigate my designs. I am wondering if this class might be a culprit for dangling object references (namely to the event handler). public class ParentFormFinder { private Control ctrl; private Form form; public event System.EventHandler FoundParentForm; public ParentFormFinder(Control ctrl) { this.ctrl = ctrl; this.ctrl.ParentChanged += new System.EventHandler(this_ParentChanged); } public Form Form { get{return this.form;} } public void Dispose() { this.Dispose(true); } protected void Dispose(bool explicitCall) { this.form = null; this.ctrl = null; } private void OnFoundParentForm(object sender, System.EventArgs e) { if (this.FoundParentForm != null) this.FoundParentForm(sender, e); } private void this_ParentChanged(object sender, System.EventArgs e) { Control ctrl = (Control)sender; do { if (ctrl.Parent is Form) { this.form = (Form)ctrl.Parent; this.OnFoundParentForm(this.form, e); return; } else { if (ctrl.Parent == null) { ctrl.ParentChanged += new System.EventHandler(this_ParentChanged); return; } else ctrl = ctrl.Parent; } }while (true); } } Mario T.

    - 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.

    - 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: GridLines in DataGrid Header 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.

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.

    - 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?

    - 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: GridLines in DataGrid Header 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: GridLines in DataGrid Header Tag: 59719

    - detecting a change in the datagrid Hello, could you tell me how to detect a change in the datagrid (i.e. when you actually change the data and click the pen symbol in the grid and not when you just tab to the next field). Therefore datagrid_currentcellchanged does not work. Thanx in advance Robert Tag: GridLines in DataGrid Header Tag: 59717

    - 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. Any illumination on this topic will be gratefully received. Thank you. Tag: GridLines in DataGrid Header Tag: 59714

    - 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. What can I do to remove all garbage in the .net project for the old form?? Regards Tore Tag: GridLines in DataGrid Header Tag: 59709

I am attempting to format a data grid. How do I set the
color for the grid lines in a data grid header. The
GridLineColor attribute in the table style does not set
the color of the grid lines in the header, it only sets
color for the grid lines in the data portion.

Thanks,
James
