    - changing look and feel of an app I would like to know if there are any examples, tutorial on how to completely change an application's look and feel. By that I mean the colors, the way menus are drawn, the way tool bar items are spaced in a tool bar, the way tab identifiers are shaped, etc., etc. There are a few interesting 'LAFs' such as MS Money 2005, MSN Messenger 6.2, Office 2003...just to name a few basic ones. I would like to have one of my graphic designer friends do a mock up in photoshop then produce an application that looks like it (I'm assuming it all has to be done programatically so designers would have to resort to something like photoshop). I also understand that part of the reason the aforementioned applications look the way they do is because of controls which are not available publicly...despite that, if designer can create websites (with primitive components) that can draw powerful and diverse emotional reactions, I don't understand why rich client GUIs have to look so ugly and gray (obviously 'consistency' has its place too). Any way, it will be even better if someone can point me to publicly available LAFs, the way we are starting to see them for the Java/SWING community. Thanks! Tag: After form loads event Tag: 82190

    - View of ListControl Item I have a ListControl on a window where the text will get clipped. The user can not see the full text nor can he scroll to view it. Questions: 1) Is there a Windows "standard" that is used for a work around. 2) Is there a way to know which item the mouse is hovering over and put up a display in a tool tip type window. I can't find a way to access the Scollbar to find out the vertical scroll on the window. I would prefer to stay away from a Combo box look as the list control is for display purposes and is not used for selection. Thanks, Marc Tag: After form loads event Tag: 82185

    - Shortcut Key question (i.e. "&Submit") I have a Button on a WinForm that has a text property = "&Submit". I noticed that whenever I pressed the "S" key only (without pressing the "Alt" key) the Button's click event would fire. I thought that it was only supposed to fire if the combo "Alt+S" was pressed. My problem is that I have another control (a DataGrid) that is suppoed to respond to the "S" key being pressed and I don't want the Button's click event to be fired. I only want it to be fired if the combo "Alt+S" is pressed. Any suggestions? Tag: After form loads event Tag: 82167

    - A Bug in .NET Framework/Windows Forms Anyone who sees this We have been grappling with this problem ever since we ported to .NET. Microsoft says that MenuItem event handlers are not garbage collected, since they are not "closely tied" to the forms. Although they keep holding the refrence to the forms and it causes the forms to not dispose. So the user objects and GDI object counts keep riising. Apparantly they dont think its an issue and the users have to add handlers for menu item events and then remove the handlers manually. If anyone has come across this issue and know of any other solution besides Microsoft's then please post it. Tag: After form loads event Tag: 82166

    - ICustomTypeDescriptor.GetEditor - Which property am I on?? I have a class that will be edited via the CollectionEditor/CollectionForm UI. To that extent I have defined the various properties I want editable for my class. However, three of the properties are of type string but I would like them edited by selection from a dropdown list whose contents are determined at runtime. It looks like I might be able to use the ICustomTypeDescriptor interface to do what I need. In particular, if I could override the GetEditor method to create a specialized UITypeEditor for these three properties then I think this would do the trick. The only problem is that I cannot see how I know, when GetEditor is being invoked, which property it is being invoked for! Thanks, -- TB Tag: After form loads event Tag: 82165

When I display a WinForms datagrid, I want the value in the first row and column to appear in reverse image. I have tried setting the CurrentCell, focusing the grid, getting the textbox and tried to select the text, etc. Each time with no luck. When I press the Tab key to tab through the cells, then the cells are reverse-imaged. But I need it that way on initial display. Tag: After form loads event Tag: 82164

    - CollectionEditor: How to specify arbitary list of values for prope I have a collection of items that I allow the user to edit by bringing up a CollectionEditor. The editor conveniently displays all the properties of my item class and works pretty well. However, I am changing one of the properties from being of an enumerated type to being a string value that should be set from a list of possible values determined at runtime. The enumerated value is automatically handled by the PropertyGrid as a dropdown list. How can I override this behavior to supply the list of allowed values at runtime? I have been successful at plugging in my own derivation of a UITypeEditor for this property but I cannot figure out how to supply the instantiated type editor the list of values to display in the dropdown.

    - Scrolling during a Drag Operation Hello all, I have a UserControl that is in a Panel. The Panel's AutoScroll is set to true. When the user drags data over the Panel and hits the edges, I want the control to scroll. I've managed to get this all to work. But I have a few questions: - Is there a standard distance from the edge of the window that the mouse should be before scrolling starts? - How much does one scroll each instance? I've tuned mine to match the speed of the machine I'm doing development work on... Obviously this may not work for others. And one technical question. To do the scrolling I adjust the AutoScrollPosition property while handling the OnDragOver event. If I do this every time the OnDragOver event is fired, my scroll bars move, but nothing is re-drawn (until the scroll bars go as far as they can). On the other hand, if I update the auto scroll position every other time OnDragOver is fired, then everything works as expected: the scroll bars move and the panel is updated. This seems odd, and I find no details on this in the documentation or in a search of the newsgroups. One other question. What is DragDropEeffects.Scroll used for? Is there any point to it? Or is it just there in case you want to change cursors. Finally -- I'm doing my scrolling in OnDragOver. Should I do it in GiveFeedback instead? I'm a little unclear how the framework expects me to seperate the tasks (currently, since I have no special cursors, I do implement GiveFeedback). Cheers, Gordon. Point mouseCurrent = PointToClient(new Point (drgevent.X, drgevent.Y)); /// /// Is it time to scroll (if possible)? Skip every other call to give /// the rest of the update framework a chance to catch up. /// //// _lastDidIt switches from true to false on each call, it is a method variable. int dragboarder = 20; int dragscrolldist = 5; if (mouseCurrent.Y > Height-dragboarder) { if (_lastDidIt) AutoScrollPosition = new Point (-AutoScrollPosition.X, -AutoScrollPosition.Y+dragscrolldist); } if (mouseCurrent.Y < dragboarder) { if (_lastDidIt) AutoScrollPosition = new Point (-AutoScrollPosition.X, -AutoScrollPosition.Y-dragscrolldist); } if (mouseCurrent.X > Width-dragboarder) { if (_lastDidIt) AutoScrollPosition = new Point (-AutoScrollPosition.X+dragscrolldist, -AutoScrollPosition.Y); } if (mouseCurrent.X < dragboarder) { if (_lastDidIt) AutoScrollPosition = new Point (-AutoScrollPosition.X-dragscrolldist, -AutoScrollPosition.Y); } _lastDidIt = !_lastDidIt; /// /// Make sure everything is re-drawn. /// Invalidate(); Tag: After form loads event Tag: 82150

    - Problem with databinding and RowChanging event I created a method to handle the RowChanging event to validate some data in a databound form. I am using BindingManagerBase.EndCurrentEdit to trigger the RowChanging event. If the data cannot be validated then an exception is raised in the RowChanging event and catched after the call to EndCurrentEdit. The problem I am having is that after calling EndCurrentEdit and raising the exception inside the RowChanging handler, the values in the controls in the form that are not modified again are not fetched again. For example... I have a form with 2 edit boxes which are data bound. Edit1 and Edit2. The original values for each are "mary" and "smith" respectively. If I modify Edit1 to contain "John" and call EndCurrentEdit, the RowChanging event is fired. If I check the Current version of the column it contains "Mary" and the proposed version contains "John". If I raise an exception within the event handler then the data is not saved to the dataset as expected. At this point I still have the edit boxes containing "John" and "Smith"... I am not calling CancelCurrentEdit because I don't want to roll back to the current values... I am simply letting the user know that the data entered is incorrect. If at this point I edit the Edit2 to "Roberts" and call the EndCurrentEdit method, the RowChanging event is fired... but if I check the proposed version of the Edit1 bound column, it contains the Current value "Mary" and NOT the value currently in Edit1. If the user does not edit the Edit1 control directly, the value is not reflected when EndCurrentEdit is called. Thanks, Jeronimo Tag: After form loads event Tag: 82147

    - Hosting .NET Windows forms UserControl in IE Hello, I need to host .NET Windows forms UserControl in Internet Explorer. I do it by including <OBJECT> tag in my aspx page: <OBJECT id="mycontrol1" classid="MyControl.dll#MyControlNamespace.MyControl" width=800 height=300 style="font-size:12;" VIEWASTEXT> </OBJECT> everything works fine, MyControl.dll gets downloaded into the download cache and IE displays the control. The problem however is the fact that the browser needs to download MyControl.dll file. Our clients will block downloads of .DLL and .EXE files. I would like to use CAB file instead, for example, I tried codebase attribute as in the following: <OBJECT id="mycontrol1" codebase="MyControl.cab" classid="MyControl.dll#MyControlNamespace.MyControl" width=800 height=300 style="font-size:12;" VIEWASTEXT> </OBJECT> but it does not work. Is there a way of making IE to download a CAB file, just as it does for an ActiveX components, and extract contents into the download cache, so that no DLL file needs to be downloaded?

    - Winform scrollbars and Maximize I have an MDI application that has 4 child windows. When my application opens, it initialially opens all of the forms un-maximized. When I then choose to maximize all of the windows and then in my code switch the app to one particular window, that one window does not appear maximized. Instead, I have to double-click on the title bar and then in the control box I see the option to maximize. Otherwise the control box shows what appears to have 'restore' capability. Not sure if this explaination makes sense. I have the autoscroll set to true on the window because the controls on the window go down farther than the height of the window. Is there something to do with the autoscroll that could be causing this behaviour? Thanks. STom Tag: After form loads event Tag: 82133

    - Prompt if changes for databinding Hi, I am writting a data navigator where if the user edits a form and tries to move to a different record on the dataset without saving the current record, he is prompted to save it before the BindingManagerBase position is changed. I created a navigator class that includes a dirtyRow flag to check when the user selects to move to a different record. I am trying to keep track of changes by adding events to TextChanged on the edit boxes of my form. If a textbox changes then the dirtyRow flag is set. However I am encountering some problems since the TextChanged event is also fired when text is changed due to the databinding for the control. I added an event for PositionChanged on the BindingManagerBase that sets dirtyRow to false and in general this works because when the position is changed, the databinding sets the dirtyRow to true on the TextChanged event but the PositionChanged event is called after the TextChanged event and therefore the newly visited row is not considered dirty until the user changes the text on the edit boxes. However this does not work the first time the form is created because in that particular case, the TextChanged event from the databinding is called AFTER the PositionChanged event. My question... 1- Is there any way of knowing IF the EndCurrentEdit will actually modify the underlying dataset? I noticed that RowState for a row changes to Modified after EndCurrentEdit if there are changes. I want to prompt the user to keep or save changes only if changes exist. 2- Is there an event that I can use to know that databinding for the form on the current position has completed so I can set the dirtyRow flag to false?

But when my tab key cause a new row to become current, my debug trace shows nothing at all. Question is, how to solve this problem.

    - WindowEnumerator My application has regular document windows and floating windows above them. I want to iterate through all windows in z-order. I would have thought this capability would be built-in to the .net framework, but everything I can find on the archives says no - you need to use GetWindow(), thus: [DllImport("user32", EntryPoint="GetWindow")] private static extern int GetWindow(int hwnd, int wFlag); And the most logical thing seems to me to be to create a class that implements the IEnumerator interface. I suspect I need an additional external function - maybe GetTopWindow? to get a starting point; call that in .Reset() and GetWindow() in .MoveNext(). Am I on the right track? Can anyone provide examples of how to call these functions, eg what arguments to pass to them, how to coerce their result types into System.Windows.Forms, how to tell when I've reached the end? Thanks in advance. Peace, --Carl Tag: After form loads event Tag: 82096

    - Updating a windows forms control from a thread I've gotten this question a couple of times in interviews and I don't know what they are looking for: How do you update a control's property, such as a textbox.text property, from a thread, in .NET? It seems to me you just update it normally. What are the interviewers looking for here? Thanks. - W Tag: After form loads event Tag: 82091

    - Window Not Responding when running external programs I have a windows form application (C#) that launches multiple external batch files to do various installation tasks. I want to show some status on the win form, say simply update the text on a Lable control, "task 1 starting...", "Task 1 completed.", etc. However, the text for the label is not being updated/showed. I understand that the window is not responding to the Paint event anymore, How do I work around this? I see programs like InstallShield can do this, how did they do it?

    - updating forms? my program draws a form and when you click the start button another form is drawn with a progress bar as it runs through a function. my issue is that when you click on another progrem then try to go back to the progress bar form it doesn't redraw itself. i tried using a: if(num%100==0) this.Update(); where num is just to count each time it runs through the loop. the program still works and finishes, but i can't seem to get the progress bar form to redraw itself. the this.Refresh() and Update() did not work either. any suggestions? btw...it's for an installer, so as it's uploading the database the progress bar goes, all of it works fine, just need the form to redraw itself if it loses focus.

    - Corrupt resx with inherited forms Hi I have a bunch of corrupted resx files. My Cs files are okay. The code stil compiles and I can still show the forms. They still work, but I cannot edit them anymore. When I try to edit, the editor is convinced it are plain cs files and not forms. How can I recreate the whole design thing?

    - Application Data Where do people put application data that is not user specific? For example, what if I have a xml file containing r/w data for a forms application, and the application may be used by users with limited rights. I cannot do any user management, and there is no reason to expose the user to the fact that these files even exist. Documents and Settings\All Users\Application Data\... is out because it is not available to restricted users. Application directory is out for the same reason. LOCAL_MACHINE hive in registry is out for the same reason. Confuzed Tag: After form loads event Tag: 82079

    - Validation problem I have a form that contains a TabControl. A tabpage on the control contains a TextBox that is bound to a field in a DataTable. The textbox is readonly. When the user clicks an Edit button, the field becomes editable. The user then has the choice of clicking the Cancel button, to discard any changes, or Update to finish the editing mode. Because the field cannot be NULL, when the user clicks Update the field should be validated. The textbox and the update button both have CausesValidation set to True, while the cancel button does not. For some reason however, the Validating event gets called when the user clicks the cancel button! Tag: After form loads event Tag: 82073

    - Panel Hello, I have a panel on a form that holds a large number of controls. When I scroll the panel down and leave the form and then come back, the panel is still in the last position I left it. Is there a way to make the panel go back to the top position. I have tried the following with no success. Dim APoint as Point APoint = New Point(0, 0) frm1Main.Panel1.AutoScrollPosition = APoint Any Suggestions will be greatly appreciated, Chuck Tag: After form loads event Tag: 82072

    - Question re Migration of VB6 App to .NET Our company develops and markets a client/server application which is written in VB6 as a rich Win32 Client/Server application. For a variety of technological reasons we are looking to migrate toward the .NET environment. However, a number of business factors make it impractical to accomplish this through an abrupt termination of the VB6 product and complete rewrite. Instead, we are looking to perform new development in .NET and slowly over time migrate existing code to .NET. At this time, we are looking to add a brand new module to our product. Obviously, the new module has some connection to the rest of the application in general. Be that as it may, it is sufficiently encapsulated unto itself that we are contemplating developing this new module in .NET. I'm interested in any advice which you can offer about how we might 'plug in' a module written in .NET into our VB6 application, specifically at the UI layer. We must provide the user with a seamless UI interface to our application, regardless of whether the user is interacting with a VB6 Form or with a .NET WinForm. Thanks very much for any advice which you can provide. - Joe Geretz - Tag: After form loads event Tag: 82071

    - Huge Memory Usage Hello all, I am writing an application in C#, VB.NET which basicaly has a form with a few pictureBoxes on it and a TabControl with 3 tab pages - in each one a treeView and a ListView. In addition it loads a few other dll's as a reference which should not be memory consuming since each have a few simple classes. The thing is - this application can take up to 40,000KB of memory!!! Any idea where to start checking? How can I debug and see what part of my application is responsible for such memory usage? One more thing: I did some tests and noticed that even a simple form with nothing on it can take up to 15,000KB , am I doing something wrong??? Thanks, Haim. Tag: After form loads event Tag: 82069

Hi
This question is probably one of the basic things but being a novice
programmer in c# and .NET environment, I couldn't get to find the answer.
I have a menu item in one form and need to create the context menu with tht
menu item in another form. The first form becomes the parent form for the
second form after the second form is loaded. So, I need to know what event
could be used as load event is called when the form is still in the process
of loading.

Thanks

Hello,

Here is an article on Events and Mdi forms. It goes into detail on how to
merge menus of subforms. If you are not using and Mdi I'm not certain what
all your options are. You could programmatically update the parent form
menus from the subform.
