    - 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: Crystal report on Win 98 Tag: 59871

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.

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?

    - 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: Crystal report on Win 98 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!

    - 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: Crystal report on Win 98 Tag: 59770

    - 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.

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: Crystal report on Win 98 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: Crystal report on Win 98 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. Any illumination on this topic will be gratefully received. Thank you. Tag: Crystal report on Win 98 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: Crystal report on Win 98 Tag: 59709

    - 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: Crystal report on Win 98 Tag: 59705

    - DrawReversibleFrame draws on VS.Net not my form I am drawing in a picturebox on a form using DrawReversibleFrame and DrawReversibleLine. It used to draw fine on the picturebox, now all of a sudden it does not appear on my form or application, but on VS.NET behind my application. Has anyone seen this behaviour, and/or is there any form/app settings that would affect this? Thanks. Tag: Crystal report on Win 98 Tag: 59703
