    - User Control binding Hi, i´ve created a user control that contains a TextBox and a Label, lets call this control CText. CText has properties like Value and Text, where Text is used to display formatted Value. Well, i´m trying to create a new databind using: cText1.DataBindings.Add("Value", wDataTable ,"TableField1" ); _CM = (CurrencyManager) this.BindingContext[wDataTable ]; _CM.AddNew() ; Then, when submitting the form (winform), i call _CM.EndCurrentEdit(); ...where it is supposed that the bindingcontext datasource should be updated..., but this is not working as expected. -> Tried the same with a TextBox and it works.... -> MSDN : You can simple-bind to any object that derives from the System.Windows.Forms.Control class...., and UserControl does, so what´s the problem?? any suggestion?

    - Hiding non-databound hyperlinks in a DataGrid I am brand new to ASP.NET and am now required to take over maintenance of a .NET/C# web application. On one of the pages I'm working on there is a DataGrid which has multiple columns. One of the columns is not databound and instead has up to three hyperlinks in it (Edit, Award, and Cancel). A couple of the hyperlinks should not be shown in certain cases. Now, mind you, I don't know if it's being done in the way that's best to do it. It looks like there is a "panel" being created to contain the hyperlinks that may not be visible. I don't know why though (i.e. why not just set hyperlink's Visible property and be done with it without a panel?). That being said, I want to change the page so that one of the hyperlinks does not show (i.e. Visible = False) based on a certain value for a session cookie. It's the Award link in the code shown below from the .aspx file in question. --- CODE BEGINS --- <asp:TemplateColumn HeaderText="Actions"> <ItemStyle HorizontalAlign="Center"></ItemStyle> <ItemTemplate> <asp:HyperLink id="hlEdit" runat="server" NavigateUrl='<%# "Edit.aspx?id=" + DataBinder.Eval(Container, "DataItem.PersonID") %>' CssClass="link-text">  Edit </asp:HyperLink> <asp:Panel ID="Panel1" Runat="server" Visible='<%# Convert.ToBoolean(Convert.ToInt32(Request.Cookies["core"]["sl"]) <= 9)%>'> <asp:HyperLink id=hlBids runat="server" Visible='<%# Convert.ToBoolean(Convert.ToInt32(Request.Cookies["core"]["sl"]) <= 9)%>' NavigateUrl='<%# "Award.aspx?id=" + DataBinder.Eval(Container, "DataItem.PersonID") %>' CssClass="link-text"> Award </asp:HyperLink> </asp:Panel> <asp:Panel ID="panAction" Runat="server" Visible='<%# Convert.ToBoolean(DataBinder.Eval(Container, "DataItem.PersonStatusCancel"))%>'> <asp:HyperLink id="hlCancel" runat="server" NavigateUrl='<%# "Cancel.aspx?id=" + DataBinder.Eval(Container, "DataItem.PersonID") + "&op=cancel" %>' Visible='<%# Convert.ToBoolean(DataBinder.Eval(Container, "DataItem.PersonStatusCancel"))%>' CssClass="link-text" > Cancel </asp:HyperLink> </asp:Panel> </ItemTemplate> </asp:TemplateColumn> --- CODE ENDS --- Now, the value of the cookie, when I bring up this page, is 1, which satisfies the condition...yet, the link still shows. I guess my question is two-part: 1) What is the best way to accomplish something like this? Do I have to use a DataList instead or can it be done using a DataGrid? 2) If this is best way to do it, then what's wrong with code above?

    - Validating of control data on Windows Forms My question is there any way to trigger controls validation from the code? I have a form where user can enter some query parameters and execute the query. Each control (TextBox, DateTimePicker etc.) has Validating, Validated handlers. If the user edits query parameters manually validation code is executed upon leaving control which is just edited. The application can also read default data from config file/command line. Such data is used to populate form controls upon form creation/loading but it does not trigger validation process. Is there any standard way to cause the Form to perform validation for all controls on the form? For all controls on particular panel?

    - Windows XP ComboBox bug when using "Windows Classic Style" I found a very odd bug while developing a Forms app with Visual Studio 2003. If you have a ComboBox with no items in it, when you click the arrow, an empty drop down list is displayed which is the height of 1 item. In Windows XP, this all works fine if you have your "Windows and Buttons" Display Setting to "Windows XP Style". However, if you change it to "Windows Classic Style", when you click the arrow in your combobox, it does not show the empty drop down list. Worse yet, the system "thinks" it is displayed so the UI is "locked" (just like when a drop down list is displayed) and your next click on the app will do nothing, because this is what would normally close the drop down list. A couple things to note: -If the combo box is not empty, it always properly displays the drop down list -It is not limited to .NET, I built a C++ app with Visual Studio 6.0 and get the same behavior -There are rare circumstances where it does work correctly in "Windows Classic View." Sometimes an empty combobox DOES display the empty drop down list, but it seems to be very rare. I can not explain why sometimes it does and sometimes it doesnt. I have not been able to come up with a scenario where I can consistanly get the empty drop down list to display in "Windows Classic View", in fact, I have only gotten it to happen a couple times. Here are the steps to reproduce (Must be running Windows XP): -Set your style to "Windows Classic Style" by right-clicking empty space on your desktop, select Properties, click the Appearance tab and select the "Windows Classic Style" in the "Windows and buttons" drop down list -Open Visual Studio and create a simple Windows App. Drag a ComboBox onto the Form. Press Ctrl + F5 to build and run the app. -You *should* see that when you click the arrow in the ComboBox, it does not display the drop down list. -Change your style to "Windows XP Style" -Now when you run the app you will see the drop down list DOES appear.

    - BUG: Nested groupbox in .NET 1.1 SP1 shows corrupted caption in themed Hello, .NET 1.1 SP1 contains a nasty bug (.NET 2.0 beta as well) which makes nested groupbox controls to show a corrupted caption text (in bold, which is chopped off) if the windows forms application is run on a themed XP system (i.e.: with windows themes turned on) and flatstyle is set to System (to enable visual styles). This affects all applications written for .NET and which use windows forms and nested groupbox controls, applications which used to work perfectly on .NET 1.1 but are now showing corrupted caption. See for a screenshot: http://weblogs.asp.net/fbouma/archive/2005/01/20/357210.aspx See for a repro case: http://weblogs.asp.net/fbouma/archive/2005/01/21/358006.aspx As the bug is pretty severe, and requires ISV's to change their applications to make them work on .NET 1.1 SP1 while there is nothing wrong with their code, I'd like to ask Microsoft to fix this a.s.a.p. I tried to contact PSS / online support but apparently I have to pay (!) for sending this information to MS, so I try to get your attention through the newsgroups. Please fix. Thanks.

    - Scrolling Problems in a Form Hi everybody, I have a little problem, no two. First my english is not quiet good so please try to understand what I want and help me, please ;) And second: I habe a Form. In this form is a ScrollableControl (modified, so it could raise scroll events), containing another Control painting an image. Okay, everything works fine, but if I deactivate the Form (it's a mdi child form) and activates another Form and than go back, the scrollbars are reseted to the default settings, very top and very left! I will get the same behavior, when I deactivate the hole application an than activate it again. If the mdi-child Forms are deactivate, there are showing the right scrollbar positions and the correct clipping of the image. Only when I activate the form, the form resets the scrollbarpositions :( Me first solution is, receiving the activate Event raised by the form and than set the scrollbar positions. This dosn't work! Than I try the receive all window messages to get the WM_ACTIVATE, WM_MDIACTIVE, WM_NCACTIVATE, WM_SETFOCUS and the WM_IME_SETCONTEXT messages. If I acted on these messages I got a really funny behavior of me application. I have deactive (by clicking to no application on taskbar) and than have activate (by clicking the taskbar icon), than the scrollbar shows again the wrong position, but when I moved the mouse of the form, the scrollbar reposition them self and show the correct positions. Now I react on every message posted throu the WNDPROC function and set the scrollbar positions. This works, BUT if I do a large/small de/in-crement scroll with one mouseclick the scrollbar do the de/increment and immediately set them back to the previous position. This isn't good :( Maybe some of you know the correct window message, so I can set me scrollbars I the form will activate by clicking the nonclient or client area, or the application and so on.

    - 2 Simple Questions Hi everyone, I have what I think are 2 pretty simple questions. I know I have done it before, but can't remember how I did it. #1: I have a windows form with a textbox. The textbox is getting filled from within a function. I need to have the scroll buttons on the text box accessable at all times, not just when the loop that fills it gets back around to the application.doevents line. I'm pretty sure there is an easy way to do this with threading. #2: This one is really dumb, but I'm having a slow day. How can I get the text box to autoscroll to the bottom everytime & add text dynamically to it? Thanks all in advance, Matt Tag: Intercepting text a RichEdit/Textbox control in another application?

    - Creating a Form From A Non-UI Thread I have a non-UI assembly that contains a Form similar to the MSN Messenger pop-up that appears when a user comes online. I have a Timer in this assembly that on regular intervals goes and looks for new information and if it finds any, displays the Form to the user right above the System Tray. My problem is that the Form comes up alright, but it seems to not be getting any Windows events like Paint and Click. Also, when I put my mouse over the Form an hour-glass displays. I am assuming that there is a problem with the Form being called from the Timer thread and have been trying to figure out a solution with no luck. One note, Iâ??m trying to design this assembly to be called from a normal WinForms application and an application that starts in the System Tray so it might or might not have a Form running. Any help would be greatly appreciated! Iâ??m done with this project except for this one â??majorâ?? problem.

    - FileSystemWatcher fails I have an app (that should really be a service, but I haven't got round to it yet) that just monitors a network folder via a filesystemwatcher for new files and then does its thing. Generally, it works fine, but it fails about once a month - which is about one every 2-3 hundred files. No error message or exceptions... it just fails to notice that the file has appeared. After that, any other new files are also ignored. I'm thinking of switching to a dir function running every ten seconds or so....but was wondering if anyone had any ideas about the situation.

    - ComboBox DroppedDown property bug. If set in constructor, WndProc messages are missing I believe I have found a bug in the System.Windows.Forms.ComboBox object. Quick background, there is a ComboBox event for when the drop down list is shown, but not one when it is closed. This is because the ComboBox does not receive any messages when it's drop down list is being closed. It's parent is what receives the CBN_CLOSEUP event notification (from the WM_COMMAND message). I wanted to know when a ComboBox was closing its drop down list so I created a UserControl with one ComboBox in it. I then overrode the UserControl's WndProc, looked for WM_COMMAND message and so on. Now for the bug... When I use this UserControl on a form, all worked fine. But to get the UserControl to act more like a ComboBox, I have to expose all the ComboBox properties by declaring them through the UserControl as properties. The first one I did was the DroppedDown property. Here is where the bug comes in. In the constructor (New subroutine) of the MainForm for the windows app, set the DroppedDown property of the UserControl to False. Now when you run the app the WM_COMMAND message is never sent to the UserControl. Uncomment out the DroppedDown = False in the Main Form constructor and the WM_COMMAND messages are now getting sent again. The steps to reproduce are below. I am not sure what is all effects, but I am running VS 2003. I believe it occurs in both C# and VB.NET along with Debug and Release mode. Steps to reproduce... -Open VS and create a new VB Windows Application (named MyTestApp) -Once it is open, right click on the project in the Solution Explorer, and select Add User Control (named UserControl1) -In the user control, add one combo box (named ComboBox1) -In the code for the user control, override the WndProc function (copy and paste) (Note that &H111 is WM_COMMAND) Protected Overrides Sub WndProc(ByRef msg As Message) MyBase.WndProc(msg) If (msg.Msg = &H111) Then Dim x As String = "" End If End Sub -Also in the code for the user control, expose the ComboBox's DroppedDown property (copy and paste) (Make sure to include the DefaultValue property) <System.ComponentModel.DefaultValue(False)> _ Public Property DroppedDown() As Boolean Get Return ComboBox1.DroppedDown End Get Set(ByVal Value As Boolean) ComboBox1.DroppedDown = Value End Set End Property -You are done with the UserControl, now go to the designer for the Main Form (Form1) -Drag a ComboBox from the "Windows Forms" tab in the toolbox anywhere on the form -Go in the code for the Main Form and change the two occurances of "System.Windows.Forms.ComboBox" to "MyTestApp.UserControl1" -In the UserControl code, put a breakpoint on the Dim x As String = "" line and press F5 to run the application. -You should see the breakpoint hit before the app even fully loads because the UserControl will have focus, which CBN_SETFOCUS is on of the WM_COMMANDs that is sent -Once you verify that the breakpoint is hit, press Shift+F5 to stop debugging -Now go into the Main Form's code and find the New() sub (it will be in the "Windows Form Designer generated code" region) -Right after the InitializeComponent() call, set the DroppedDown property of the UserControl to false (copy and paste) ComboBox1.DroppedDown = False -Make sure your breakpoint is still set on the same line and press F5 to run the app again. This time you will notice that by setting the DroppedDown property in the constructor, the UserControl now does not receive any WM_COMMAND messages. Comment out the line and you will see that once again it receives the messages. I cant figure out why this is. It seems to be a bug, but I would imagine it does not come up that often. Here is a similar topic I found but I am not sure if it is the same behavior. It references a HotFix from Microsoft but that does not sound like the same behavior I am getting. http://groups-beta.google.com/group/microsoft.public.dotnet.framework.windowsforms.designtime/browse_thread/thread/2bf345185534b268/b02fad6f3c9afc85 Tag: Intercepting text a RichEdit/Textbox control in another application?

    - Dynamically Added Textbox (no KeyDown, KeyUp, KeyPress events fire) I am having a strange problem with a textbox that I am dynamically adding to a form. What I am currently doing ------------------------- I have a set of questions defined in a database. Each question can have a variable number of possible responses and can be laid out differently. I have an answer factory class that gets the correct answer control (RadioButton, TextBox, CheckBox) and provides it to a question control. The question control then adds the answer to one of its panels. All this seems to work a designed...I can add any number of questions and answers to a question list control in a variety of different layouts. The Problem I am Encountering ------------------------- The problem occurs with textbox controls. They display correctly, however, the KeyDown, KeyUp, and KeyPress events are not firing for the textboxes (in other words, I can't type anything into the textbox). However, if I have 2 textbox controls in the same container (panel), I can always get the KeyUp, KeyPress, and KeyDown events to fire by tabbing from the first textbox to the second. Once I do this, I can then start typing into both textboxes without problem. I am completely stumped. Thanks for your help, Doug Tag: Intercepting text a RichEdit/Textbox control in another application? Tag: 83034

    - DataGrid Control Selected Index Hello, I am using a DataGrid control to populate an all customers list. I would like the users to be able to scroll up or down the list press Enter and the customer record populate on another form. I am able to accomplish this only with the Click Event, and it only works if you Click the Row Indicator on the far left side of the DataGrid. The problem seems to be realed to the cells of the DataGrid having focus at the time when the Enter key is pressed. I've tried using the CurrentCellChanged event and still cannot get the KeyUp Event to fire. Is there anyway to accomplish this? I would rather cell browsing not be available to the users and the DataGrid's RowIndicator to all ways have focus. Any Help is appreciated. Thank you Tag: Intercepting text a RichEdit/Textbox control in another application? Tag: 83027

    - Can't override ShowDialog Hi: I have a set of derived forms that I wish to implement an 'Execute' method to launch these forms, but I also wish to hide the 2 inbuilt ShowDialog methods so these can't be called unwittingly. I have tried: private new DialogResult ShowDialog() { } private new DialogResult ShowDialog(IWin32Window aParent) { } but these are completely ignored and the 2 methods are still visible and usable. How can I hide these? TIA, Martin. Tag: Intercepting text a RichEdit/Textbox control in another application? Tag: 83006

    - Probs with visual inheritance and DataGrid columns Hello! I've got the following problem: I add a form frmBaseForm to my project, this form contains the DataGrid named let's say dgInvoices which has the table style named tsInvoicesData with several column styles named: tsCompanyName, tsValid, tsValidUntil. Then I add an inherited form to the project, which inherits frmBaseForm that's where the problems start: in the inherited form I have a DataGrid with the same name as on the base form dgInvoices, BUT the table style name is DataGridTableStyle1, more than that, column styles names (shown in property browser) are DataGridTextBoxColumnStyle1, DataGridBooleanColumnStyle1, DataGridTextBoxColumnStyle2. Why it happens this way? Why Buttons, TextBoxes, Panels etc. are shown in the inherited form with the same names, but Table/Column styles are not. The most interesting thing is, that if I go through inherited form members in run-time using Reflection I find these Table/Column styles under names which are assigned to them in the parent form (tsInvoicesData, tsCompanyName, tsValid, tsValidUntil) not which are visible in the property browser for the inherited form. Could please explain me this weird behavior of the IDE, is it normal or not, if it is normal, then WHY?! If not, then is this fixable and how?

    - Custom Control Property HelpText Property Yeah, reading the subject, it makes no sense...but here goes.. I made a textbox control w/ some added features...the problem is, whenever I go to use it, I forget what my custom properties do. Is there a way to put helptext into the custom properties so it appears in the bottom of the property window like all of the standard properties of standard controls? I think if it can be done it has something to do with accessing the appropriate attribute of the property using the system.reflection namespace...but yeah, I don't know, that's why I'm asking!

    - "Restructure a Windows application" from scratch in 2 months Hello Everybody, Please guide me so that I can fulfill this challenging assisnment ... I have been asked to "Restructure a Windows application" from scratch in 2 months. The existing application which is working but it is very heavy as no proper application architecture and layering has been followed for this. It was really hard to maintain (as I was maintaing it till now) . First let me tell u a bit about my application ... This appliction uses Window forms UI with a lot of panels put one on the top of other.There are few separate forms for login etc. This UI interact with webservices to get the data from our database and show in turn on UI. Three Windows services are updating our database from some other remote database after regular interval. So in this way we keep our database updated with real data. Thus client UI don't has to wait for long to get the real time data directly from the original source.We are currently deploying the Client UI from web and using C# as language. Being new to dotnet technology, I don't know how to start with this. Some of the facts/questions that are coming to my mind after studying my application and the concepts ... 1. There is a lot of hype and demand about UML Tools like "Rational Rose" etc. I want to use it to redevelop my application. 2. Microsoft recommends the "Application pattern and practices" to design the application. I am presently going through the following topics ... .NET Data Access Architecture Guide http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnbda/html/daag.asp Desinging Data Tier Components and Passing Data Through Tiers http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnbda/html/BOAGag.asp Although these are very good resources but these are very vast and taking a lot of time. Sometimes I am not able to follow these articles as I don't have extensive experience. Could you please point me towards 1 or 2 sample applications of "Similar Kind" (Preferably with Full UML diagrams/documents) with of course easy to understand documentation and source code, so that I have the practical view of "Microsoft Pattern and Practices" and I can instantly follow them. It would be better if these applications are not very complex and yet inclue the layering concept as well as the usage of all technologies -Web Services,Windows Services,UI,SQL Server connectivity etc. 3. What is the best way to use Panels/Forms. Is it good to show multiple panels on the same form and when needed use visible for 1 panel and invisible for multiple panels or use multiple forms? And why the respective practice is used? Thank you for all of your patience to go through such a long mail. Please advise me the best way to go about it keeping in mind the time constraint of 2 months. Thanking you in advance, Regards, Rajat Tandon.

    - Calling winForms in Installer project I had build an installer project for my ASP.NET project. And found that several fields need to be configured, like the web.config files and etc, which requires user input. Also I need to attach my database using the installer project, anybody could suggest how I could perform similar action? One of my idea is to build a winform project which accepts athe user input and configure the fields during installation, but I had no idea how winform object is being called during installation. Any idea and suggestions are welcomed! Thanks in advance. Regards; weichung Tag: Intercepting text a RichEdit/Textbox control in another application? Tag: 82994

    - Smooth scrolling I am developing a windows application for scrolling through multi page tif documents (similar to ms word style). I am having difficulties achieving a highly smooth scrolling affect. I load the entire tif into a memory stream and access it from there. I am using a picturebox like control to view each page of the tif, I scroll through viewers using the autoscrollbar on the form. The problem seems to lie in the way the image is being repainted, when scrolling up or down quickly there is the 'frames' affect, the screen does not seem to finish repainting the new display area before the paint event is raised again and another repaint begins (theorizing?). As I continue to scroll down it looks as if the same small portion of image is repainted a dozen times until it fills up the screen, the problem is solved after the scrolling has ended and the paint is able to redraw the screen completely. How can I smooth out the scrolling?? As well, is there any limit on the size of a form and distance a scroll bar can scroll?

    - Update a database Hello, I have an application that sends a transaction across a Domain (on a LAN) to another computer inside the domain that is functioning as a Datastore. When the transaction is sent to the datastore it is always successful, but 90% of the time the first 3 entries (Paramaters) are being duplicated from the previous transactions.i.e. InsertCommand.Text = "INSERT INTO Customers Values(?,?,?,?,?,?,?,?,?............)" Parameter(0)....... Parameter.Value= IDNumber Parameter(1)....... Parameter.Value = CustomerAccountNumber.Text Parameter(2)...... Parameter.Value = txtLastName.Text etc. etc. etc (About 110 Parameters, Above example is not actual code just brief idea to explain the problem) when this command is wrapped in a transaction or simply sent to the datastore. The querry is sucessful, but alot of the time the IDNumber will be good, but the CustomerAccountNumber (Built on the fly) and the txtLastName are being duplicated from the previous customer information. I have noticed it is only happens to the first 3 or 4 fields. I am sure that the form has different data but the database is showing (When I view it) that there are multiple individuals with the same account number. Could this have something to do with the network? The network is using DHCP and the DSN for each computer on the network are routed to the Datastore IP and the Domain Computer's IP. Any suggestions will be greatly appreciated. Thanks, Chuck Tag: Intercepting text a RichEdit/Textbox control in another application? Tag: 82982

Hi,

Anyone know how to intercept the messages/text to a textbox control in
another application using .Net? I know that Spy++ can do this, how is
this accomplished?

Been trying to avoid using global hooks to do this, but i don't know of
any other way.

As a workaround, I've been able to use the SendMessage with WM_GETTEXT
to poll the control on a timer to retrieve the text, but ideally I'd
like to intercept the messages to the textbox instead, if at all
possible.

Any advice?

Thanks,
kc
