    - Work Offline Solution Needed Hi am about to create a N-Teir Solution Using SQL Server 200 as the Data Teir, XML Web Services as the Business Layer and Winforms as the presentation layer. I will be using Datasets that will peridically update the data back to the SQL Database. I wish to implement a Work Offline feature. That works now, untill the App is closed. What are best practices for storing data locally. Keep in mind that this application will rely on web services to get data and stored proceedures etc. Is there a solution already for this IE a namespace?

    - Adding an 'internal' control to the toolbox. I frequently define internal UserControl-derived classes in my WinForms apps: internal class MyUserControl:UserControl{ ... } I'll often need to embed these controls in a Form, whose class is contained in the same assembly as the control. As far as I know, the only way to do this using the designer is to add the UserControl-derived object to the toolbox and then drag it from the toolbox to the target form. To accomplish this, I use the toolbox's Add/Remove Items functionality. When adding new UserControl(s) to the toolbox, the user is asked to choose an assembly containing the UserControl. I browse for and choose the assembly that I'm currently working on, call it /debug/MyAssembly.dll. The problem is that the toolbox is only prepared to accept UserControl items that are declared as "public," not those declared as "internal." For a variety of reasons, I'd much prefer to have UserControls declared as internal if I'm not exposing them to the outside world. The only workaround is to temporarily change the scope of the UserControl to public, recompile, Add the item to the toolbox, change the modifier back to internal, and recompile again. I then have access to the control from my toolbox. This clearly an ugly workaround. Do you know of an easier way to add internal controls to the toolbox? Thanks...

    - Printing Graphics.PageBounds not accurate Hi, I'm writing a check printing program that needs to put a MICR line 6/16" from the bottom of the page. Since the checks will be printed on a laser printer using letter sized paper the printable area is not actually 8 1/2" x 11". I'm using an HP LaserJet 4000 and it cannot print all the way to the physical page boundaries. It has the following limitations: Top Margin = 0.18" Left Margin = 0.25" Right Margin = 0.25" Bottom Margin = 0.28" The problem I'm having is the the graphics object being passed with PrintPageEventArgs is reporting its PageBounds property as the full physical page size (850, 1100) instead of (804, 1050). The other properties are as follows: Top = 0 Left = 0 Right = 850 Bottom = 1100 Width = 1100 Height = 950 I would have thought the PageBounds would be as follows: Top = 18 Left = 25 Right = 1075 Bottom = 822 Width = 1050 Height = 804 It appears the drawing methods in the graphics are scaling the e.Graphics.PageBounds to fit within the physical page bounds which makes it difficult to position gdi objects at exact physical locations on the printed page. In other words I can draw anywhere within the e.Graphics.PageBounds and the results are visible on the printed page. Is this a known bug in the .net printing or is it possibly a problem with my printer driver? Microsoft word does not have a problem determing what the physical bounds of the printed page are. Is there some other way to get the physical page bounds so that I can rescale the drawing points and rectangles? Thanks for your help, Gregg Walker Tag: Heavy Net Framework 1.1 Tag: 76682

    - Tab Control ComboBox Here's one! I have a Tab Control that consists of 4 Tab Pages. These pages will be removed and added as needed as the user checks and unchecks certain checkboxes. On the Form_Load event, I am calling routines that populate the various ComboBoxes List's that are contained by these Tab Pages. When these Combo Boxes are populated, I initialize the text property with a 'String.Empty'. At this point, the Tab Pages have not been added to the Tab Control. Now, when the user adds a Tab Page to the Tab Control, such as : tabStaff.TabPages.Add(tbSystemUser) the text property is automatically being set the the first item in the list. This is what I DON'T want to happen. My Qutestions are: Why or How are these properties being set and How can I prevent it? Any ideas would be greatly appreciated, Jeff Tag: Heavy Net Framework 1.1 Tag: 76680

In I.E and other browsers there is the ability to increase the text size of the page you are viewing. Is it possible to get this functionality into a windows form with the web browser in place? ideally i would like to have a button that increases the size and one to decrease it.

But this call returns 0 indicating that new style is not been updated. I am curios how does rich text behaves when configured to emulate the normal edit control. basically I am trying to use rich control because it has the ability to change the line spacings. All rest of the functionality of the rich text box, I want to be same as the normal edit control. Any clues / pointers on the same. Thanks and Regard sk Tag: Heavy Net Framework 1.1 Tag: 76668

    - scrollbar problem.. Dear all, I'm writting a .net winForm application with C#, but I'm getting the following exception when the user scrolls a scrollbar. The strange thing is that the exception happens only some of the time, and seems pretty random. However, once an exception occurs with a scrollbar and when I choose 'continue', that particular scrollbar will raise the exception everytime I click on it from that point on. Anyone encounter the same problem before? Any solution to this problem? At the very least I wanna know how I could catch that exception.. Thanks~!

    - Use a "Satelite info form" Hello, I've the following problem: From within my main form I want to lanuch another form for displaying some information. Launching this information form form the main form's load event results in a info form which is blocked (means can't be used because seems to be in the background) I got the same result when using the VisibleChanged or the Activated (first call only) event (I my opinion events fired when the form is "really") But now launching this information form from within a buttons click event or a timers tick event results full working form beside the main form. My questions are: What is the difference and how can I launch a working info form within the main form's load event? Thx Thorsten Tag: Heavy Net Framework 1.1 Tag: 76661

    - Can you intercept click event? Hello, I am trying to control tooltips in my winform. I want to only turn them on when the user chooses a menu item called WhatThe. When they do I change the form's cursor to Cursors.Help and activate the tooltip. The problem is I don't want the user to actually be able to interact with the form while in this state. If they click the mouse I want to intercept that event and set the form's cursor back to the default and deactivate the tooltip. Is there a way I can intercept all click and double click events on the winform? And if the cursor is currently set to Help cancel the event otherwise forward it on to what ever they were clicking on? I would also want to treat the keyboard the same way (if in help mode any keyboard event would take it out of help mode). thanks, Scott Tag: Heavy Net Framework 1.1 Tag: 76654

    - Does global declarated "iexplore.exe" exist? Hi. I've got a little not typical problem right here. I would like to open using InternetExplorer ("iexplore.exe") my link from my application. I do it like that: System::Diagnostics::Process::Start(S"iexplorer.exe", S"www.wp.pl"); And it works, but problem is - I have to check does "iexplote.exe" (or other Web Browser) exist. I do it like that: if(System::IO::File::Exists(S"iexplorer.exe") == true) { .... } and it doesn't work - because "iexplorer.exe" isn't located in local folder but is declarated as global in system (global example: using CMD check "iexplorer.exe www.wp.pl" - this page starts correct). How can I get true/false does this exe file exist, using name of web browser executable file? ("iexplore.exe" or others execs) declarated as global ? Good day, thx for wrote.

    - Selecting a combobox item when textchanged event fires... I have an odd problem with a combobox and selecting an item in it. I have a combobox that has handlers for both SelectedIndexChanged and also TextChanged. In the TextChanged handler, if the text matches one of the items in the combobox, the SelectedIndex for the combobox is set to that item. This fires the SelectedIndexChanged event which enables/disables some other controls. Seems pretty simple. However, when I then click my OK button and go to the form closing event handler, the SelectedIndex has been changed to -1. I have verified that I am not doing this anywhere in my code. If I simply select and item in the combo box, things work fine and SelectedIndex is not -1 when I get to the form closing event handler. There is something different between the two, but I have no idea what it is. I set the SelectedIndex programmatically and end up in the same SelectedIndexChanged handler, but the selection is lost sometime later. Any ideas? I'm stumped.

    - SelectedListViewItemCollection problems Hi All, I understand that to get the items that are selected in a listview, you read the SelectedItems porperty of the list view. The type of this property is SelectedListViewItemCollection, and this type is meant to be defined in System.Windows.Forms.dll. But whenever I try use this type, I get compilation errors saying that the type SelectedListViewItemCollection is unknown. I have made sure that my solution has the System.Windows.Forms.dll in its references, and that I am using the correct using statement (using System.Windows.Forms;) but I still have this problem. I am using Framework 1.1. Does anyone know what the problem could be, or if there is any solution? Is there something wrong with my System.Windows.Forms.dll assembly?

    - Distorted control position or form size under XP Hi, I'm developing a Win Form App under VS.NET 2003, Win2K English SP4, in VB.NET I have a form which have a datagrid (anchor left, top, bottom, right) in the middle of the form and a button (anchor bottom, right) placing at the right buttom corner of the form. The form display as expected in the deployed Win2K SP4 English and WinXP SP1 English machines. It was displaying correcly in WinXP Chinese SP1, until I changed the "WindowState" property of the form in designer to "Maximized". After that, when it is running in WinXP Chinese SP1, the datagrid area spread all over the bottom of the form, and hided the button at the right bottom corner of the form. The control cannot be displayed properly in that XP Machine even after I resize the form in run-time of that App. Anyone has encountered it before or any ideas ? Very much appreciated. Thanks!

    - Embedding Forms I would like to design a number of separate forms in Visual Studio, and then at runtime embed them into an area of another form (without borders and title bars of course). The forms will all be placed in the same area on the main form, and which forms are used is dependent on navigation choices made by the user. The container for the forms could be the main form itself, a panel on the main form, or a tab page on the main form.

    - Multiple Errors with Visual Inheritance editing forms in Designer We are creating an application that uses visual inheritance having a FormBase.cs class as the base for all our forms. We have created this in a seperate project(Utilities.dll) in which all out other projects reference. We can add and create a form pretty easily inheriting from the FormBase class. What will happen is once the Utilities.dll is rebuilt and/or another user just gets latest from vss they get a multitude of errors and no one consistantly. One time we'll open the child form to be editied and we'll get one of the errors below, re-open the file and get another of the errors below. For example here are a few: -"Unable to load configuration file[]" -"Resource transformation for file 'StartPage.resx' failed. Insufficient state to deserialize the object. More information is needed." -Popup message complaining about some _FormBase... object already being delcared. -Other resx file errors that I cannot reproduce at the moment. We have a work around fro the first one most of the time: 1. Exclude file from project. 2. Re-add an exsisiting item then open it in form designer. 3. If that didn't work, close the project and re-load it 4. Close down vs.net and restart. These all seem overkill for trying to make a enterprise windows application base on recomendations from Msft. If anyone as info on how to fix this please post! Thanks, Ron Tag: Heavy Net Framework 1.1 Tag: 76589

    - PropertyGrid and nested property I have a custom control derived from button. One property is an instance of the following simple class, which is used to paint the button with different colors: Public Class Style Private _ColorStart As Color Private _ColorEnd As Color Private _ColorHighlight As Color Public Property ColorStart() As Color Get Return _ColorStart End Get Set(ByVal Value As Color) _ColorStart = Value End Set End Property Public Property ColorEnd() As Color Get Return _ColorEnd End Get Set(ByVal Value As Color) _ColorEnd = Value End Set End Property Public Property ColorHighlight() As Color Get Return _ColorHighlight End Get Set(ByVal Value As Color) _ColorHighlight = Value End Set End Property End Class The property is declared like this: <TypeConverter(GetType(ExpandableObjectConverter))> _ Public Property ClickedStyle() As Style Get Return _ClickedStyle End Get Set(ByVal Value As Style) _ClickedStyle = Value End Set End Property Note that I have applied the TypeConverter attribute so that in the PropertyGrid, the property can be expanded to show the individual colors. This seems to work ok. The problem is that, when I change the individual colors, it does not seem to affect the visual display of the button. Not on the designer nor at runtime. For example, the defualt colors are red. In the designer I can change the color to blue and it seems to be changed, but on the form the color of the button does not change, nor does it change at runtime. At runtime, when I inspect the property, it still has the default values. It seems like the property is being changed in the PropertyGrid but the button object is not reflecting the change.

    - How to install an app on a network etc... I have a windows forms app which I would like to install to a shared drive and folder so that all the machines on our intranet can access it and run it without me having to go around to every machine in the building to run the install program. I deffinatley do not want 500 copies of all the files installed in everyones Program FIles folder if you see what I mean. The problem is that the app has some 3rd party frameworks it requires for example Crystal Reports which I believe needs to be installed via the merge modules that come with the tool. So, what I am looking for is a way to install everything to a network folder, and then maybe just run a script on each machine that will make whatever entries are required.

I have a windows form class that contains a Font private member which is initialised (new'ed) in the forms constructor. The font is used in formatting a richtextbox control. Do I have to dispose of the font member in the forms Dispose method or does this happen automatically because it is a member of the form? I think I need to call font.Dispose on it but I wanted some confirmation on this first. If I do have to call Dispose on it should I do this in the form's Dispose method?

    - Access the ComponentTray Hi, I'm writing an add-in that adds controls to a form at design time. I got this working for visible controls on the form by getting an IDesignerHost for the form, and adding to the Controls collection of the RootComponent, but this doesn't work for components in the ComponentTray (I want to add an ImageList). I suspect I need to call the Add method of the Controls collection on the ComponentTray, but I don't know how to get to the ComponentTray object for a Form or UserControl. Any ideas ? Thanks in advance. Cheers, Joris Tag: Heavy Net Framework 1.1 Tag: 76559

    - datagrid : navigation keys hi, I have a derived DataGridColumnStyle, with a custom textbox. If i press left or right navigation keys, the custom textbox losses focus and move to other cell, instead of moving position between the character in the textbox (editing). Tried to intercept navigation keys by overriding ProcessCmdKey, but that only disable the Left and Right key. Thanks. Tag: Heavy Net Framework 1.1 Tag: 76557

    - MapPath and Windows Forms Is there a simple way to find out the physical path of a website from a Windows Form application? Example: I have a website (http://localhost/test) and I would like to find out the physical path of this website. I've looked into using MapPath (System.Web) in its different contexts, but can't seem to make any of them work. Is there a way to query IIS to find this out?

    - Image Property on PropertyGrid I am using the PropertyGrid and I have set the SelectedObject property to an instance of my custom class. One of the properties of the custom class is a bitmap. The PropertyGrid lets me assign a bitmap ok, but when I want to delete it, I cannot do it. For example, in Visual Studio when you set the background image for a form, you can highlight it and press delete to clear the property. But for my own class and the PropertyGrid, it won't do this. Can anyone shed some light on how I might accomplish this? I tried specifying the editor as the ImageEditor using the Editor Attribute on the property, but that made no difference. I just want the user to be able to selcect the image property in the PropertyGrid and press delete to clear it.

    - Async Delegates, CallBack and UI Thread Gentlemen, My question is simple. When my WindowsForm calls an Async Delegate which has a registered CallBack, is the CallBack always executed on the UI Thread? Or, do I need to test to see if it is? In my application (MDI), I have a main form that launches another form. When that child form loads it executes an Async Delegate who's target is a method on a static class (Controller). The CallBack is registered on the child form. In the callback, I check the IAsyncResult and if it was successful, I want to trigger an event on the MDIParent to launch another WindowsForm. Problem is, the second form is never launched. I can step through the execution in the debugger, and can see the callback getting executed, it runs to the event call and then everything stops. UI doesn't freeze or anything like that, it just doesnt launch the second form. I have noticed that sometime the second form does launch, but it appears as though the thread it's on is blocked. It appears briefly, freezes, and then disappears. It definately appears as though the callback is executing on the worker thread and that the events are being fired in that worker thread. That would explain the blocking and possibly the reason for the form to close (apparently after the thread is finished processing). If it is on another thread, then would I use the ISynchronizeInvoke interface to test whether the callback is on the UI thread? How would I reference the form where the callback is registered?

    - Intercepting tab focus change question Anyone know how to intercept (reliably) the tab focus change for any control on a container? Basically what I'm trying to do, is have it so that if the user is on the last control in the tab order on a tab page in a tab control, it will move to the next tab, and set the focus to the first control on that new page instead of what it does right now which is to move out of the tab control to the next control outside of the tab control. Any ideas would be apreciated. I tried overriding the wndProc for the tab control itself and there weren't any events firing on it. Thanks! James Hancock Tag: Heavy Net Framework 1.1 Tag: 76543

    - Add Root Nodes to tree view Ive got an app with a treeview and to add a new node I have a context menu. My code will add a new node as a child of the currently selected node. If no node is currently selected (or the tree is empty) then a root node is created to the treeview otherwise it is created as a child to the current selected node. ...Simple yes!! Unfortunately when one node has been created to the treeview it is impossible to get this to add nodes to the root because the TreeViewList seems to require one node is selected when there are nodes in the collection. After creating the a new node I am setting the TreeViewList.SelectedNode=null but this seems to be reset to the currently selected node. Apart from having an option to create a root node (which quite frankly will be a bit naff) is there any way around this? Br, Mark. Tag: Heavy Net Framework 1.1 Tag: 76540

    - Events of ContextMenu of a Treeview when menu is shown. I have a form with a treeView control that displays a contextMenu when the user right clicks on a node in the tree. I'm having a hard time figuring out how to resolve a problem. After the user right clicks on a TreeNode, causing the code to be run below, the contextMenu is displayed. This is ok. The problem I'm having is when I test the following scenario. After the contextmenu is displayed, the user doesn't want to click a menu item, but click on a different node in the treeview control. The next click on the tree doesn't create a click event for the treeview. Instead, it just moves the contextMenu to the spot where the user clicked. The kind of action I assumed would happend, is the contextMenu would go away, and the treeviews mousedown event fire. Can anyone suggest the best way to accomplish this task? I've been looking at events for the both the treeView and contextMenu, and nothing seems to be an obvious choice. One funny thing I've noticed is that if the user clicks off the menu a second time, the desired action occurs. It's just that first click after the contextMenu is displayed that acts funny. private void treeIIS_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e) { if (e.Button == MouseButtons.Right) { Point clickPoint = new Point(e.X,e.Y) ; TreeNode node = treeIIS.GetNodeAt(clickPoint); if(node != null) { // Highlight the node that the user clicked. //The node is highlighted until the Menu is displayed on the screen treeIIS.SelectedNode = node; Point screenPoint = treeIIS.PointToScreen(clickPoint); Point formPoint = this.PointToClient(screenPoint); mnuContextTree.Show(this, formPoint); } } } Tag: Heavy Net Framework 1.1 Tag: 76538

That's normal. Norice that the CLR and some libraries must be loaded in
order to run the applications.

There is always a performance hit with initial application execution in =
any managed environment, but once the initial hit it taken for the JIT =
to produce the IL code; managed .NET applications could outperform =
unmanaged applications.

For the ability to use the language of my choice, C#, Perl, JScript, or =
the many other languages too access a common set of libraries =
supportable by any Windows operating system from Windows 98 or better; I =
think that's a good trade off.
