    - Abuse of GDI+ resources Recently some friends were looking at some code written by an outside contractor. In the code, there was a great deal of use of pens and brushes without disposing of them. What surprised me is that the system never seemed to run out. The brushes and pens were being created in every paint event. I suppose it's possible that the garbage collector was getting around to them often enough to finalize the pens and brushes, but I doubt it was happening often enough to keep up with the use. I've always thought of pens and brushes as very limited system resources. Is that no longer the case with Gdi+? Also, in a similar vein, we were discussing the use of a static pen object to optimize drawing in a control. Is this considered acceptable? I mean, the pen (and I presume its underlying GDI+ handle) are going to be held for the lifetime of the app if it's static. Can someone help modernize my understanding of GDI?

    - Application Signed with strongname cannot use an assembly which is not signed? Hello, I came across with a problem... I had developed a component which it's assembly does not have a keyfile for strong name... One of my customers tries to use it in an application where he attaches a keyfile for strong naming it and when compiling it he gets "Does Not have a strong file Name" error pointing my component's dll... Does anybody has a solution for this? Do I have to generate a strongname for my component? Thanks in adnvance, Özden Tag: playing flash swf files using .NET C# Tag: 73682

    - Anchor Property Ignored On Custom Composite Controls I have a composite custom control (VB.NET) which is constructed of several other controls, such as command buttons, a listview etc. I have several controls which border the boundary of the container and have their anchor properties set accordingly, for example, ensuring a button stays on the right border when the control is resized. Now in the control's design view everything works correctly, controls are correctly repositioned. However, when I put the composite custom control on a form, the anchor properties are completely ignored, for example, in the form's design view when you resize the control, the child controls with the anchor property set don't move, and even in runtime the control has not correctly resized. Now obviously I could manually control things in the resize event, but this defeats the point of the anchor property, which works for single controls, so why not for a custom control. Has anyone else experienced this and found a solution or at least knows why it happens? Thanks In Advance, James Tag: playing flash swf files using .NET C# Tag: 73678

    - ParkingWindow revisited This issue was already reported by several others but I did not find any useful solution / workaround. The problem happens in a random non-frequent manner when I run my WindowsForms application. I get the following exception: Cannot access a disposed object named "ParkingWindow" In another post in this NG titled "Derived combo box controls in forms - MessageBox.Show breaks the control's message routing" Clive Dixon describes a potential reason for the problem. However, no practical workaround is suggested. Could someone from MS suggest how to avoid this issue?

    - Issue with Data bound Text box validation I have a C# Windows forms application which uses XSD file created in memory dataset. On one of the forms I have bunch of text boxes to enter values for various columns of a table and they all are data bound. For one of text boxes value entered must be unique and I want to check this uniqueness as soon as user leaves corresponding text box after entering any value. I have tried following two methods and none seems to be working 1. If I try to attach a UniqueConstraint on corresponding column then it will not get fired until acceptchanges is not called and thus I cannot validate value as soon as user leaves field. 2. If I try to get a DataView with a rowfilter based upon value entered by user then it does not looks into rows which have â??modifiedâ?? or â??addedâ?? row state. I have tried to use all possible combination of DataViewRowState enumeration values but nothing seems to be able to force returned DataView to include modified or added status rows. Thus I get duplicate values in table So I have two questions â?? 1. Is it possible to enforce UniqueConstraint before AcceptChanges is called on Row / Table (may be in column changing event itself)? 2. What can cause an DataView to skip â??modifiedâ?? or â??addedâ?? row state rows even if DataViewRowState. CurrentRows has been specified for RowViewState of DataView? My apologies for possibly a vague explanation of my problem and thanks in advance for any thoughts. Tag: playing flash swf files using .NET C# Tag: 73676

    - NullReferenceException in UnsafeNativeMethods.CreateWindowEx Hi all, I have the following situation. I create AppDomains on demand to host winform based controls from C++ host. I'm using .NET 1.1. I tried to do AppDomain.Unload from background thread to free up the main GUI thread and make it more responsive. When I try this, I get the exception, listed below, always on the 3rd AppDomain and control creation. I tried getting SystemEvents through reflection and calling Shutdown manually. This delays the problem. It almost doesn't happen, but still re-appears sometimes. This doesn't reproduce in .NET 2.0 alpha. Is there any way I can work around this bug/limitation? I also would like to know what is being null inside the UnsafeNativeMethods.CreateWindowEx or under what conditions. Maybe I can work around the problem.

    - Button swallows keys. Bug? Workaround? The Setup: ================ I have a cardswiper attached to my keyboard, so that when I swipe a card I get "keyboard input" that looks something like: %748a45a1246fbac9d8fdeaf3572f221b? I would like forms in my application to handle these card swipes. To this end, I've made a base Form that sets KeypPeview=true, and that overrides the ProcessDialogKey method. The Bug: ========== This setup works well, except in a few circumestances. One common circumstance is if I have buttons with shortcuts (e.g. a button whose Text attribute is "&add member". Here "a" is a shortcut. I have noticed that if any button on the form has the focus, then "a" is consumed by the button and does not make it to ProcessDialogKey. If something else (like a listbox) has the focus, then I do receive the key in ProcessDialogKey. Does anyone have a solution, an idea, or a workaround? Thanks in advance!

    - Proxy servers and embedded windows control in IE Hi there, I have a windows control embedded in a web page using the <object> tag. The control sometimes needs to access an aspx page using HttpWebRequest/Response (aspx page is located on the same web server that the .dll file is located in). This works perfectly when the client is not connecting through a proxy server. When the client is connected to the web via a proxy server, myHttpWebRequest.GetResponse() would fail with a 407 Authentication Required. I realize that any HttpWebRequest object has a Proxy property, but whenever I tried to access it I got a SecurityException (Request for type WebPermission failed). So to temporarily get past this problem, I gave the dll FullTrust for my computer. Now no exception is thrown when I try to access the Proxy property. New problem. I got the proxy information using GetDefaultProxy(). It is able to grab the address for the proxy server because I was able to do MessageBox.Show(proxyObject.Address.ToString()). So I *assume* I have the proxy information. However, when I try to do a myHttpWebRequest.GetResponse(), I still get a 407 Authorization required error. There does not seem to be any login/password for the proxy server... or if there is, I don't know how to find it. So is the cause of the problem because the proxy server thinks that whatever is running the dll (I assume the JIT compiler or whatever) is trying to access the proxy server? Or if not, what is the problem and how do I go about fixing it? Thanks, Wendy Tag: playing flash swf files using .NET C# Tag: 73658

    - Forms question (.) I've created a custom control. And now I've done something that prevents me from using the designer to layout controls on my custom control. I tried deleting the .resx file, thinking the VS would just regenerate it, but did not. Here's how I got the problem: I created a new user control. I called it BaseControl. I created another new user control. I called it DerivedControl. After VS generated the .cs file, I changed the base class to BaseControl. EG: public class BaseControl : System.Windows.Forms.Control public class DerivedControl : BaseControl Now I am unable to add controls to DerivedControl using the designer. I have to manually create the code in .cs file. This gets really hard to lay things out. So, what I can do so that I can use the designer?

    - Change Cursor over ActiveX control Hello, I am trying to build a form that can display HTML content in the background and various controls in the foreground. I am able to achieve this using the WebBrowser activex and adding foreground controls to the form. So far everything is ok. My problem is that I want to control the Cursor over the controls and the background. Since the WebBroser (my background) is an activex, I cannot control it's cursor! I had also problems in this configuration with mouse events, but thanks to you guys that one is now solved with IMessageFilter.

    - Problem: HowTo update UI from workerThread? Hi! I want to update an userinterface from a background thread. I think that a good way to do this is to use to use methodinvoker in UI-thread and then begininvoke in workerThread to pass parameters back and update the UI. But i have one question. The Method i start with begininvoke is a public sub on another class (not the UI-class). Do I have to pass the form (like a reference) to the other class which the workerthread uses to be able to use it´s begininvoke method? Is this a good way to do this. Here is my code: Public Class Form1 Inherits System.Windows.Forms.Form #Region " Windows Form Designer generated code " ' Some code Me.Label1 = New System.Windows.Forms.Label ' Some more code #End Region Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim workerThread As New MyWorkerClass Dim mi As MethodInvoker = New MethodInvoker(AddressOf workerThread.StartWork) mi.BeginInvoke(Nothing, Nothing) End Sub Public Sub UpdateLabel(ByVal o As Object, ByVal e As System.EventArgs) Dim myEvent As MyLabelEvent = CType(e, MyLabelEvent) Label1.Text = e.LabelText() End Sub End Class Public Class MyWorkerClass Public Sub StartWork() Dim e As System.EventArgs While True e = New MyLabelEvent("Text on label") Dim lst As Object() = {Me, e} ???.BeginInvoke(New System.EventHandler(AddressOf ???.UpdateLabel), lst) DoSomeWork() End While End Sub Public Sub DoSomeWork() End Sub End Class Public Class MyLabelEvent Inherits System.EventArgs Private _labelText As String Public Sub New(ByVal label As String) MyBase.New() _labelText = label End Sub Public Property LabelText() As String Get Return _labelText End Get Set(ByVal Value As String) _labelText = Value End Set End Property End Class Best Regards / Steve Tag: playing flash swf files using .NET C# Tag: 73637

    - MDI Menus Bug? Hi all, I've found a straing error (NullReferenceException) in a MDI Environment with two children merging menu with the MDI Container. By changing active child from one with menu to other without I finally get the exception. Anybody knows if menu merging is unstable? I'm using VC# and NET Framework 1.1 on XP Pro. TIA.

    - TabControl - change the tab shapes and appearances? I have tried without success (using C#) to change the standard rectangular tabs (for the TabPages) to look like the ones in Messenger - funky curved jobs. However whenever I try to overwrite an existing tab, either by superimposing a bitmap over it, or by manually drawing a new shape with the Graphics methods, the standard rectangular tab outline always shows through. I captured both the DrawItem and Paint events. I saw a partial solution in Code Project, which used a wrapper DLL around UxThemes.dll, but this involves installing this extra DLL with my product. And I couldn't get it to work anyway! It seems this is a known problem in .NET. A colleague using C++/MFC had no trouble doing this. Any suggestions? - please!

    - Big picture question - Custom control concepts Maybe it's just late but I'm having some trouble with custom control concepts. Do I understand this correctly? If you define a custom control, you are responsible for defining all events and properties, even if it inherits from an existing control that has the events you want? (ie - none of the parent's basic events are exposed available automatically?) Tag: playing flash swf files using .NET C# Tag: 73613

    - Disposed forms problem I have a simple problem: In calling form: Private _theForm As MyFormClass() ' in a button click event... If theForm Is Nothing Then theForm = New MyFormClass() End If theForm.Show() The problem is if I close theFrom, then click the button of the calling form again, theForm Is Nothing will evaluate to False (meaning it's a valid reference), yet when theForm.Show() executes, I get an exception "Cannot access disposed object named 'theForm'" Even if I call Dispose on the called form when it's closed, the problem doesn't go away. I thought it was just some garbage collection issue but calling GC.Collect/WaitForPendingFinalizers before theForm.Show() does not make any difference. As a workaround, I could trap the exception in a try block but I was hoping for a more elegant solution, like simply inspecting a property. In the first place, why does theForm Is Nothing evalute to False when the form is already closed/disposed? Many thanks =) Tag: playing flash swf files using .NET C# Tag: 73610

    - Data Conversion in a grid I have a custom grid control and I'm stuck on an issue in the data binding. Using a method similar to the DataGridColumnStyles class, I have a column style class that allows you to map the bound datasource fields to the grid columns. I've added a Format property which will take a format string such as "{0:C}" which will then convert the underlying data to a currency string. This works very nicely. The problem is when the user goes in and edits data. Let's say that a column has the above currency format string and the data in the cell is $4.45 If the user changes the value, I need to then update the data source. I need to handle the situation where the user puts in either $4.50 or 4.50 and be able to properly convert it back to the underlying type. Is there an easy way to do this without doing a huge case statement for all the different data types? The underlying data can, of course, be of any type. In the grid it's represented as a string. All I have is the format string to know about formatting. I'd rather not have to parse the format string to figure out how to parse the underlying data. Is there some way I can use it to do the parsing? Thanks. Pete Tag: playing flash swf files using .NET C# Tag: 73607

    - Comunication Between Threads C# Sorry I forgot to specify the language I am using the language I'm using is C# . Hello, could anyone give me a help on the best way to transmit the results of a function in a thread to where she has started from ? Problem is if i'm not in error that the function launched by the thread has to be void... So, I can't return anything. What's the best way to do this ? I have heard of IPC but don't have mutch knowledge of this but looks like "you" write the data to a file and then read the file, from the main process. Thank You in advance for any help.

    - Convert Access application to .NET? I have a small-medium sized Access application that is poorly written. My choices are to either rewrite large parts of the Access app so that it functions reasonably well, or to convert the whole thing to .NET. Not being an Access developer, the .NET approach seems most natural, but I want to do the right thing for the client (even if I end up giving away the contract). I posted on the Access forum and got the impression that my fears about Access being an unstable piece of junk were unfounded, and that most of the things that need to be done in this type of application could be done quickly and easily in Access and the rest could be coded as one would do in any other environment (just have to give up the "free" things that Access provides). Does anyone have any experience with this type of conversion? I would be interested in your thoughts. Alfredo Tag: playing flash swf files using .NET C# Tag: 73602

    - Preventing forms from showing up before their layout is completed Hi, When my forms show up (i.e. visible set to true), they show up immediatly while their components (labels etc...) are still being displayed. This gives the application a very unprofessional feeling. I would like to know if there's a command to fix that. I would like my components (forms, panels) to not show up until everything in them is processed and ready to be displayed. Thanks in advance for any help! Ana L.

    - Complex properties in custom controls I have a control, let's call it MyControl. One of the properties of MyControl is MyControlStyle. MyControlStyle is a class with a number of properties. MyControl always has a valid instance of MyControlStyle (it is instantiated in the field declaration). In the property grid, I want to lay out the items in MyControlStyle when someone selects a MyControl on the form. They are all simple data types and don't require any sort of custom designers or anything in themselves. How do I get the properties of MyControlStyle to show up in the property grid without duplicating the properties in MyControl. I mean, if I have to pass the properties through like that then it's kind of pointless to have the MyControlStyle class separate. Thanks. Pete Tag: playing flash swf files using .NET C# Tag: 73585

    - WinForms, Events, and Subscribers Background -------------------------- I am in the process of creating a WinForms app with many forms. I have a set of forms that all subscribe to events on a custom object. When the forms are created I manually create a subscription in the form to one or more events in the custom object. (BTW, this is the same design pattern used by IssueVision discussed at DevDays). I have a controller form (MDI parent) that determines which child form is currently being viewed. When a new child form is selected, the current child form is manually closed [using Form.Close()] and disposed [using Form.Dispose()] and then the new form is shown. This keeps only one child form open at a time. Question -------------------------- Even after child forms are closed and disposed, when events are raised from the custom object, the events are still triggered in the disposed child forms. Could someone explain why this is happenning? I must be misunderstanding something. Do the child forms need to manually unsubscribe from the events in the Closing event? Is there a better place to do this? TIA, Doug Tag: playing flash swf files using .NET C# Tag: 73583

    - Need advice on making a MessageBox replacement I'm looking to make an enhanced MessageBox. I want to make it work very much like the regular MessageBox as far as developers are concerned, so I'd like to use the Show() method to display it. However, I want it displayed modally, which we normally achieve with ShowDialog(). Is there a way that the called form can force itself to display modally, or can you think of another way I can do this? Another question I have is about icons. I want to pass a standard MessageBoxIcon enum to the Show() method and then display the OS-specific icon that was requested. In other words, it'll look different on XP than on 2000. To this end I can't simply stick a graphic in my assembly. I can probably figure out how to DRAW the icon myself, it's RETRIEVING it from the system that's beyond me right now. Suggestions?

    - ImageList Errors - What a crap! Hi, Whenever I add images to imagelist and running my application I encounter this error: ------- An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll Additional information: Exception has been thrown by the target of an invocation. Then it highlights the following line in my application code: Me.ImageList1.ImageStream = CType(resources.GetObject("ImageList1.ImageStream"), System.Windows.Forms.ImageListStreamer) -------- Also, the value of "Me.ImageList1.ImageStream" is "Nothing". I have looked up some Microsoft site for this, but couldn't really solve this problem since it happens for images of every size . Thanks in advance --- OS = WinXP Pro VS.Net 2003 Framework 1.1 PS: Where is all those.....Net Microsoft talked about? If they know that DI cracks with so many exceptions, then why did they release their product ? Doesn't any MS guy take responsibility for all these mistakes?I have paid money for their product, you know? Tag: playing flash swf files using .NET C# Tag: 73577

it is possible to use and display flash SWF files on .NET WinForms
applications?
If so, how?

Use the AXBrowser control. This hosts the IE browser in a control you can
drop on a form and navigate to an SWF file on the local hard-disk.
