    - Display Union query in a datagrid? Hello, Is it possible to display a union query in a datagrid? If so how? If not what alternatives do I have? What I am trying to do... Primarily; I have two tables that contain related information and share similar columns. I want to merge them for reasons of display. Secondarily; I hope to be able to update either table individually - Column content will distinguish for the system which table to update. Is this possible?... how? -- dbuchanan Tag: System.Windows.Forms.TextBox and Magtek Credit Card Stripe Reader Tag: 92366

    - Catching MDI Application Closing I have an MDI application with a number of child windows. In each child window I am catching the Closing event and having the child window decide if it should set cancel to true. The intent here is to ensure that no child window can close while it is in a state where user entered information can be lost. I have just noticed that while the Closing event is caught if I click the X on the child window, it is not caught if I click the X on the MDI parent window. Is there some other event that I am missing here? Thanks, Ron L Tag: System.Windows.Forms.TextBox and Magtek Credit Card Stripe Reader Tag: 92365

    - error with events in html-document in mshtml/axwebrowser? HELP !! When using AXWebroswer in my Windows-Forms app it is impossible to catch all events of the displayed html-document. It only works with a few events. See the following example: //get the IHTMLDocument2 mshtml.IHTMLDocument2 htmlDoc = axWebBrowser1.Document as mshtml.IHTMLDocument2; if ( htmlDoc != null ) { // get the input item elemnet HTMLInputTextElement input = (HTMLInputTextElement) htmlDoc .all.item("id1", null); if ( input != null ) { // register eventhandler ((HTMLInputTextElementEvents2_Event)input).onclick += new HTMLInputTextElementEvents2_onclickEventHandler( this.Text_EventHandler ); } } private bool HTML_EventHandler(mshtml.IHTMLEventObj e) { MessageBox.Show("Alert from the html:text event" ); return true; } It is possible to register the appropriate event handler, but it is never called !!! But it works when i register an event handler for the click-event, see the following example. // register eventhandler ((HTMLInputTextElementEvents2_Event)input).onchange += new HTMLInputTextElementEvents2_onchangeEventHandler( this.Text_EventHandler ); Is there a different and working approach to catch these events?

    - 4 pane SplitContainer The SplitContainer divides the space in two, either horizontally or vertically. I'd like to divide the space in four. By adding more splitters, the problem is that they don't keep in synch automatically. It'd be nice if when the mouse hovers in the center of the four regions a cross movement icon is displayed, and movement in the two axis is allowed. With the solution of adding more splitters the user is forced to first move in one direction and then in the other one. What do you recommend to achieve this? Thanks.

    - Adding forms into a panel Hi everybody: I am adding several forms into a panel to give MDI appearance to my panel.. Though the forms inside my panel looks fine, I have three problems: 1. The focused form does have the title bar activated (it is gray, like the inactive forms) 2. The only way to bring to front a form is clicking the title bar (in a MDI container, the user can click at anyplace in the form and it gets activated). 3. Cascade, horizontal tile and vertical tile functionality is not provided. Well, the tile and cascade window organization can be implemented, but I do not know how to deal with the focus and mouse problem. Am I doing something wrong? There is another way to implement this functionality? Thank you in advance Ernesto Tag: System.Windows.Forms.TextBox and Magtek Credit Card Stripe Reader Tag: 92332

    - MDI Child Controls If I have a second form that is a mdichild, let's say frm2 and I want to update a textbox control pragmatically... In my MDI parent, I open 5 instances Dim f as new frm2 private sub OpenForm() for i = 0 to 4 f = new frm2 f.mdiparent = me f.show end sub Now, from my parent, I want to update a textbox1 in the active mdi child, how can I? When I just try f.textbox1.text = "some text" it updates the control on the last handle created. I tried finding the active child but couldn't determine how to go from there after I got it.

    - Forms are re-locating Hi, I have an application which shows forms on two different independant screens. The Windows desktop is spread across these screens. The forms are all set to manual positioning, and so to show a form on the second screen, I simply set the coordinates to be on the second screen and that is where it goes. It now seems to have developed a problem however: When I trace through what is happening all the coordinates get set correctly, and then I call Show() for the form. When show returns, the forms coordinates have been changed to show it on the first screen. I can't trace into the Show function, as it's part of the framework, but something weird is happening. Has anybody seen this before or got any idea what could be going on? Thankyou in advance. Paul Cheetham. Tag: System.Windows.Forms.TextBox and Magtek Credit Card Stripe Reader Tag: 92320

    - FindDialog for RichTextBox problem Hi! I created a FindDialog for RichTextBox. I have 2 problem with it: - when I ShowDialog() my FindDialog, it got the focus and the RichTextBox stop displaying its current selection (it apparently need the focus to draw it), so when the user click "Find Next" I select the next match, but the user has no visual feedback :-/ - I also try the RichTextBoxFins.Reverse option, doesn't seems to work at all! Any ideas? -- If you're in a war, instead of throwing a hand grenade at the enemy, throw one of those small pumpkins.

    - Combo refresh/binding problem Hi- I have two combobox controls (among other controls) that are all bound to dataset0 from the "Main" table. Combobox2 is bound to a column that contains a FK (system_id) which corresponds to the PK from the "Systems" table. These combobox's also function as picklists and as such are filled from two corresponding datasets (dataset2 contains the system_id (PK) and SystemName column from the the "Systems" table. The contents of Combobox2 depends on the selected item in combobox1. usage model is as follows: The controls are all bound to dataset0 by a hand-coded procedure at form load. This works fine. Combobox1 is populated by dataset1.fill. The user can scroll through the dataset0 records from ""Main" table by navigation buttons. The displayed string values in the comboboxes change accordingly. When the user wants to make changes, he opens the current record for editing but using a button which unlocks the controls. He then makes a selection from dataset1 loaded in Combobox1. All good so far. The change event on Combobox1 fires, and the contents of Combobox2 should then be loaded by dataset2 which takes a parameter based on the selection made in combobox1. This is used a parameter to the dataset2 which should populate combobox2 with the appropriate choices for the selection made in ComboBox1. But what is reflected in combobox2 is a bunch of rows that all say "System.Data.DataRowView" I should mention that this was a port from a VB6 where this worked correctly. The combobox2.datafield property was set to an integer (system_id) representing a FK in a column in dataset0. When the user chose the value in Combobox1, the value was sent as a parameter which was used to a recordset which yielded values to populate ComboBox2. This recordset came from the Systems table. ComboBox2.boundcolumn was set to Systems.system_ID (the PK), and the Combobox2.listfield was set to Systems.systemname. Since the control was bound to FK system_id from dataset0, whatever value it was sitting on, would display the correct systemname. Obviously, I have no idea how to make this scenario work in .NET. Any help would be appreciated. -- thx, jf kaminsky Tag: System.Windows.Forms.TextBox and Magtek Credit Card Stripe Reader Tag: 92315

    - What makes this code slow This code resets a form with two cbo's (comboBoxes) and one datagrid. The first cbo (cboSelection) selects a main table and filters the second cbo. The second cbo (cboView) selects the secondary table which determine the dataAdapter used to fill the dataGrid. Both cbo's are populated by filling dataAdapters.

    - Application.ThreadException becomes unwired? Hi, I'm writing a C# application that uses Application.ThreadException to handle uncaught exceptions gracefully. However, I'm having a problem where it is failing to catch some exceptions, and I've determined this is because the event handler is becoming unwired: if I reinstall the handler just before the code that causes the exception, the Application_ThreadException method is called. Do you know of anything that can cause this to happen? I've tried to replicate the problem in a less complex testbed project, but have had no success.

    - Satellite Assemblies and Win Forms Hi, Iâ??m creating a project which uses Satellite Assemblies (SA) to isolate localized resources. The solution contains eight library projects, one GUI control project and one Windows Form project. I know how to approach SA for library projects, but I do not have any idea how to do it for Windows Forms and Controls. Should I use Localizable properties on every win form and win control that I create and copy resource files associated with form/control to SA? Or should I just create resource file in SA with the exact name as the resx files of form/control? Which approach is better? Or maybe there is another, different approach that I should consider? Which approach will allow me to modify form/control in the design view? --Start: Different question but still about resources Can I use String Resource Tools to create resx and corresponding cs file and then split them into two separate projects â?? resx and string file (string file is created by String Resources Tool) will go to SA, and cs file to new library project? Or maybe I can access cs file in file created by SA? --End. Iâ??ll be grateful for yours help. Kind regards, Jakub G. Tag: System.Windows.Forms.TextBox and Magtek Credit Card Stripe Reader Tag: 92259

    - Problem using API CreateBitmap function and keeping transparent co I have a C# DLL that loads a bitmap object from a PNG file. Thanks to Bob Powell's advice i managed to access the Bitmap data using the lockbits method and then call the Windows API function CreateBitmap successfully. Then the DLL provides a COM interface which returns the handle to the bitmap created using CreateBitmap function. The problem is that the initial bitmap has a transparent background color, and when using the CreateBitmap function, the bitmap seems to loose this color, which is then replaced by black (maybe something to see with ColorPalette). Furthermore, the createdbitmap is a 32bit bitmap so the alpha layer which contains transparency informations should be the same. So i don't know what i missing or doing wrong. here is the code that creates the bitmap : Bitmap bitmap = (Bitmap) Bitmap.FromFile(@"C:\tmpicon.png"); BitmapData data = bitmap.LockBits(new Rectangle(new Point(0,0), bitmap.Size), ImageLockMode.ReadOnly, PixelFormat.Format32bppArgb); IntPtr HBITMAP = CreateBitmap(bitmap.Width, bitmap.Height, 1, 32, data.Scan0); NB : I also noticed that when opening the PNG file with MS Paint, the transparent color is replaced by black, whereas opening it with Photoshop or Windows Picture viewer, the transparency is visible. Can't explain this... I'd like to understand what im missing to keep the transparent color on the created bitmap. Thx for any help.

    - MouseUp event "falls through" FileDialog and activates control underneath Hello, In my app I have a UI control that responds to MouseUp events and opens a FileDialog. If an item in the dialog is double-clicked (instead of clicking on it then clicking OK) AND that item is over my UI control, the final MouseUp of the double-click is registered by my control and its handler is called, opening the FileDialog again. The events happen in this order: MouseDown MouseUp Dialog Opens Double-click in dialog Dialog closes MouseUp DialogOpens, etc. I'm looking for suggestions on how to correct this. I've tried removing the MouseUp handler when the FileDialog is opened, and adding it beck when it is closed but that doesn't work; it still gets called. I've tried looking for a way to "eat" the MouseUp but haven't found a way that works. For example, purging the event queue or marking the event as being handled/ignored. So, any suggestions?

' Me.HideEditBox() ' return focus to the DataGrid control Dim box As DataGridTextBox = CType(Me.TextBox, DataGridTextBox), Value As String ' Do not write data if not editing. If box.IsInEditOrNavigateMode Then Return True If TextBox.Text = "" Then ' in this example, "" maps to DBNull SetColumnValueAtRow(cm, RowNum, DBNull.Value) Else ' Parse the data. Try If ValidateContents(TextBox.Text) Then Value = FormatContents(TextBox.Text) Else return false ' to retain the old value This is the problem. End If Catch Return False ' Exit on error and display old "good" value. End Try SetColumnValueAtRow(cm, RowNum, Value) ' Write new value. End If Me.EndEdit() ' Let the DataGrid know that processing is completed. Return True ' success End Function Commit function is being called twice when I have the return stmt. If I take it out the Value is nothing and I am losing the old value in the cell. Tag: System.Windows.Forms.TextBox and Magtek Credit Card Stripe Reader Tag: 92206

    - Application.Run() Does anybody know why some components like Microsoft.DirectX.AudioVideoPlayback.Audio rely on the Application.Run messaging system while other events in other classes dont? Anyone got a reasonable way of testing that using NUnit as well? Thanks in advance for any help offered. Jax Tag: System.Windows.Forms.TextBox and Magtek Credit Card Stripe Reader Tag: 92205

    - changed Property of Public Control a Designtime on UserControl disapears! Hi, I'm having some weird behaviour, and I can't find any solution to this. I made a UserControl (uclCommands) which contains a Toolbar (ToolBar1) with Modifiers = Public. I put this usercontrol on my form and call it Ucl1. In the Property Window in the Windows Forms Designer I change Ucl1.ToolBar1.ButtonSize to a bigger value. Everything goes fine: The buttons get the larger size. but after I compile, the ButtonSize gets again the original size..... Does anybody knows why this happens, and what I can do about it? I really need this because my Usercontrol must have different sizes in my application. I tested this with Visual Studio 2005 beta 2 and VS 2003: Both the same behaviour... Any help or hints would be really appreciated! Thanks a lot in advance, Pieter Tag: System.Windows.Forms.TextBox and Magtek Credit Card Stripe Reader Tag: 92204

    - Howto pass a cookie to a web browser I have a windows application in vb.net which communicates with different webservers. In some cases I want to start the internet explorer (or another browser) with the current session. How can I pass the session cookie to the browser?

I am writing a Windows Forms application where I am using a Magtek credit
card reader, a "wedge", to read input into a TextBox control. I am trying to
process the input in the TextChanged event handler. The problem I am having
is that only the first character of input from the card magnetic stripe is
captured in the Text property. In fact, when running in the debugger with a
breakpoint in the event handler part of the text that is read gets written to
the source file! This causes all kinds of problems in the application.

I have done this on a Web form using the System.Web.UI.WebControls.TextBox
without problem.

What, if anything, can I do to capture the input from this device into the
Text property of the Windows.Form.TextBox?

Any input would be appreciated

Thank,
EagleRed
