• Windows Forms Adding UserControls to control collection at run-time

  Greetings! I am building a survey application for Windows Mobile, in which I am going to read from a .xml file to obtain the questions and then render the questions in a kind of dynamic form on the screen. To do this, I'm trying to create a NameSpace with classes for the different types of questions that are possible, each one of them inheriting from Windows.Forms.UserControl, and I plan on instantiating them dynamically upon reading the already mentioned .xml file. This is how part of the NameSpace looks like: Namespace clsQuestionTypes Public Class TextQuestion : Inherits UserControl Private lblQuestion As Windows.Forms.Label Private txtAnswer As Windows.Forms.TextBox Public Sub New(ByVal Question As String, ByVal TabI ...Show All

• Windows Forms Deleted value is obtained even after the value is deleted from the NumericUpdown control

  Hi We are using NumericUpdownControl of VS2005. Here we have a problem in the following scenario: 1. Enter some integer value(Ex: 1234) into the numericupdown control. 2. Now select all the value from the control and delete it 3. In the LostFocus event of the numericupdown control if we check for the value of this control it shows as 1234. Actually it should not have any value. (We have checked same for the textbox control and followed the same procedure it shows nothing for the lost focus event of the textbox control) So why is that numericupdown control still shows the value. 4. After the numericupdown control looses its focus to next control and if we see the numeric updown control it has nothing in that. But if we click ...Show All

• SQL Server missing credentials

  Hi evebody of the community!! I have a ReportViewer showing a report correctly showing some cities grouped by states.

• Visual Studio Tools for Office Could Not Load Assembly 'Office, Version=11.0.0.0,............

  Hi, I am performing Word 2003 automation using C#, VSTO 2005. When the application is deployed, it works fine on most of the machines, but in a few scenarios i get some errors like "System.IO.FileNotFoundException: Could Not Load Assembly 'Office, Version=11.0.0.0, Culture = neutral, ........." The machines where the automation fails too have Office 2003 installed, but whenever some excel is opened, it proceeds to perform some installation. It could be because of Office not being fully installed. Is there any way to check the same using C# to whether the minimum Word requisites are met on the machine prior to performing the automation using C# Hi Amrish This sounds like a configuration error of the Office install ...Show All

  is there any way of easily converting numbers eg. from decimal to binary fuctions or whatever also how can i send focus to a masked text box on load, i tried using MaskedTextBoxName .focus() but it didn't work, only seems to work on buttons. than after that how do i send focus of the text box from 1 to another like after it is filled, like 3 numbers, like those on programs typing the registration number.

• Visual Studio Express Editions VC express - entries of menus appearing multiples times ..

  Hello, Edit: here is a link to a picture that tells everything! http://img78.imageshack.us/img78/9119/desktopnx1.jpg I encounter a strange and annoying problem with VC++ express (I tried both US and French version - with and w/o SP1) : straight after the install it works but after a while the entries of the top menu (e.g. file - edit - view - format ) are appearing several times : e.g. "'file" may appear 2, 3 or even 10 times .. same for all others items and same for sub-menus (e.g. there may be 3 or 5 "File - New" entries) .. The problem gets worse with the time since the "extraneous" menu entries tend to fill the whole space .. plus some keys like backspace are sometimes not working .. I have re-installed several times but it does not c ...Show All

• Visual Studio Express Editions how to: bind a single control to multiple datasources

  hi, im really new to programming and i was wondering if there's someone out there who's kind enough to teach me how to bind a single control (ex. a textbox) to multiple datasource's (ex. two or more table's). thanks a lot.. to make a drilldown type system from combobox's, you need to have combobox's and implement their selectedIndexChanged event. This is so you can "filter" your records to be displayed on the next combobox. So going from "general" -> "specifics" - logically that should make sense. you are narrowing down your choices. In this example I am going to do, lets imagine having a database. This will store the names and addresses of people. Just an example. So we will want to get the list of ...Show All

• Smart Device Development ActiveSync

  The activesync version I'm using is 3.8, and i'm developing in Visual Studio .NET 2003 in C#. I'm also using the mscomm.ocx for communication to the serial ports. I currently have an application open when I cradle my PocketPC. That works fine. But the point of that Application is to read data. I expect it to be just random characters, I just need to know that it is in fact communicating with the PPC. Any ideas on how I would go about this. I currently have the following as code (InitComPort is a subrouting I created that is initiated in the constructor) private void InitComPort() { com.CommPort = 1; com.RThreshold = 1; com.Settings = "9600,n,8,1"; com.DTREnable = true ; com.InputMode = MSCommLib.InputModeConstan ...Show All

• Visual Basic Use of TAB key,

  Dear all, I am creating a data entry form using VB.Net. I have different controls grouped by different groupboxes to make my form easier to read. I have set tabindex property of all controls in an order but when I use TAB key to move from one control to another, it moves properly within a groupbox only. When jumping from a control in a groupbox to another control in an another groupbox it won't jump in order I set to them. I have used code to force jumping order by using keydown event like if e.keycode=keys.tab then abc.Focus() if e.keycode=Keys.Enter then abc.focus() But only Enter key works, the TAB still doesn't work as I want it to. Pls help me on this thing. Thank you very much. ...Show All

• Windows Forms combobox

  Hi, At present I am populating a combo box in winform .net 2.0 It is populated using something like the following method: cbo.datasource=dataTable .datamember= .valuemember= How can I add an empty item in the very first item I tried something like: cbo.items.add("") before the .datasource line, but no change. This is required so that when the form loads, the combobox is populated but no item should be shown. Thanks We append a blank value to our DataTable (if we don't already have one in the table) before we bind it to the comboBox : With dt Dim row() As DataRow = .Select( "ContactTypeDesc= '' " ) If row.Length = 0 Then Dim row1 As DataRow = dt.Rows.Add() ...Show All
