    - DateTimePicker BackColor Property Hi, for those of you, who need a backcolored DateTimePicker control: this ist my implementation of the BackColor property for the standard DateTimePicker Control (which does not work): public class MyDateTimePicker : DateTimePicker { #region internal set backcolor hack private Color _BackColor = SystemColors.Window; public override Color BackColor { get { return _BackColor; } set { _BackColor = value; Invalidate(); } } protected override void WndProc(ref Message m) { if (m.Msg == (int) 0x0014 /* WM_ERASEBKGND */) { Graphics g = Graphics.FromHdc(m.WParam); g.FillRectangle(new SolidBrush(_BackColor), ClientRectangle); g.Dispose(); return; } base.WndProc(ref m); } #endregion } ... seems to work quite well. claudio Tag: Component Errors Tag: 51969

    - Is print preview in .NET wothwhile? Hi! I am preparing to write a small library for generating reports. One of the key features is that it must support print previews. .NET has a PreviewPrintControler but according to the docs it is keeping the whole preview in Images. The library should be able to preview quite large reports (over 100 pages) also on resource starving computers (like 64 MB RAM 300 Mhz Celerons). Would PrintPreview eat the whole memory available or does it have some optimizations to counter the problem? What are your experiences? Regards! Micha³ Ziemski Tag: Component Errors Tag: 51940

    - Possible ToolBar bug The following Form-derived class illustrates a problem I am having when a ToolBar is instanced at the bottom of a Form with a simple Panel at the top. When this form is minimized and then restored, the layout logic leaves the Panel not fully occupying the available client area.

    - Win98: DragDrop registration fails everytime I'm ripping a thread that I created a few days ago, since I used the exact same subject line as a previous one. In addition, I can also say that since I posted this thread, I've come to the conclusion that this application is hitting some sort of wall with regards to Window handles. I'm leaning towards this being one of the primary issues because when a user selects a "tool" from a Form (it launches the core application, which is quite large), you can immediately kill the Form, go back to the tool selection Form...select it again, and it will _always_ fail to load the 2nd time. The application just dies. Furthermore, I've got try/catch blocks all over the place, sending the Exceptions to a logfile, and nothing ever gets logged once it gets in this state. You're forced to do the ole' Win98 CTRL-ALT-DEL at that point. So, the question is this: If I'm correct (or partially) in that Window handles might be the culprit, how do I resolve it? I spent an entire day forcing dispose() on everything I could possibly think of, as well as using things like the Performance Counters to identify problematic (meaning, resource hungry) classes, and I still get the same result... Can anybody (Microsoft?) help or even give me some kind of direction? Here's the original post... ----------------------------------------------------------- I have a C# Application that is posing some interesting issues when run within Win98. Let me preface this by saying that everything works like a charm under Win2000. Anyhow, the current issue is that under "certain" circumstances (there's no logic as to how/why this happens), you will fire up this application under Win98 and get a "DragDrop Error: registration failed" MessageBox from JIT. The source code line in question is, of course, a simple "this.AllowDrop = true;" property. If I were to remove it, the problem would go away. Of course, I need that call in order for the application to function correctly. And before anybody asks the obvious, I _do_ have the following line in my main Form: [STAThread] static void Main(string[] args) I can't really make heads or tails out of this issue, and it definitely presents itself only under Win98. This particular Win98 machine is up to scratch, in terms of patches/updates/etc. The OS has IE6.0 installed, as well as .NET runtime v1.1. The Application is compiled using .NET Studio 2003. Can anybody shed any light on this? Any workarounds? Tag: Component Errors Tag: 51926

    - Inherited Forms Lose Tab Order 1.) Create a form with a tabcontrol. 2.) Change the modifier of the tab control to "protected" 3.) Add 1 tab to the tab control. 4.) Create a second form that inherits from the first. 5.) On the new form, add a 2nd tab to the inherited tab control. 6.) Swap the order of the tabs so the new tab occurs first. 7.) Save and close the forms. Re-open the 2nd one. Notice the tab order was not preserved. Bug? Workaround? Tag: Component Errors Tag: 51918

    - CustomEditor on collection for a component I'm trying to use a custom editor for a property in a component. The custom editor shows a dialog. It appears the custom editor is not calling the SET property when its done. I've tested this with other samples and it does there. Could this have anything to do with the fact that the type of the property is an ArrayList? Bill Tag: Component Errors Tag: 51917

    - Setting Application directory as path for database.

    - Validation + Malicious input Hello All, I am currently developing a windows form which transacts data with a database, using web services. These transactions are the heart of the application, as 98% of the tasks allowed on the UI bind to the web service. Due to the implicit need of assuring the user does not enter wrong data (SQL Data Types) or INJECTS malicious code, where can I find good information on windows forms data validation->(priority 1) and avoiding malicious code avoidance->(priority 2)? - The big question is: is there something like a asp:InputValidator on WindowsForms, or do I have to deal with it down to the nitty gritty? Thanks for all the replies, any resources are welcome Francisco Tag: Component Errors Tag: 51904

    - HelpProvider bug? Close the .CHM window and application closes too! Has anybody else seen this? I have a Windows Forms application that simply uses the HelpProvider control to open a .CHM. I use the helpprovider.show method and it works fine. However, when the Help window (*.chm) opens, if I quit (i.e. close) the Help window, then it closes as expected, and so does my application! ?? This isn't supposed to happen is it? how do I overcome this so that when I close the Help window, my application stays open and running?

    - Few questions regarding building MSI using VS.NET Hi, I am building MSI for my projects using Visual Studio.NET and facing some problems with this. 1) I want to add a shortcut to another EXE which is not included in the MSI. How to add this? Visual Studio.NET allows us to create a shortcut for files that are included in the project / MSI whereas WISE allows to do the same. 2) When we create the MSI using VS.NET, the default setting for installation is to install "only for the you" but not for "anyone who uses the computer" ( you can see this option in "User information" dialog while installing any MSI. I could not find any place in VS.NET setup project to change this option. This is very essential to assign the MSI using Group Policy. How to change the default option? 3) Is it posible to change the dialogs and to add any custom actions? Any Help?? Advance thanks, Ramana Tag: Component Errors Tag: 51867

    - ListBox Performance - SetSelected Hi there, I have the case where I am trying to optimize some slow code that selects listBox items. For approximately 6,500 items, the IndexOf method takes about 3 seconds on a 2.4GHz machine, and SetSelected takes about 9 seconds. The label lookup from the lable map takes about 0.004 seconds. Is there any way of selecting items in a quicker, possible batch fashion? SelectedIndices appears to be read only. Surely it can't take 9 seconds to select all these indexes when only 10 or 12 are displayed at any one time. I've tried SuspendLayout() and ResumeLayout() to try to avoid code that updates the display after every selection, but the performance remained the same. for(int i = 1; i <= aenumElements.Count; i++) { string alabel = m_idLabelMap[aenumElements[i]] as string; int aindex = listBoxElements.Items.IndexOf(alabel); if(aindex >= 0) listBoxElements.SetSelected(aindex, true); } Any tips would be greatly appreciated (short of re-working the use case to not require 6,500 elements of course).

    - Is it true that Windows Forms don't use config files? WROX's "Professional ADO.NET" makes the following statement on page 54 when discussing obtaining connection strings from a config file: "In Web applications this file must be name web.config. In Console applications, the configuration file also ends in .config, but is prefixed with application name, such as MyApp.exe.config. Windows Forms applications do not use configuration files." I am curious why Windows Forms do not use config files and also what about Windows Service apps (or they treated as "console" apps?)? Tag: Component Errors Tag: 51842

    - Datagrid: Full Row Select and Other Options like in TaskVision All, Maybe I'm just missing it but how do you do the following three things with a WinForms DataGrid... 1: Make it so when the user clicks on any part of a row the FULL row becomes selected 2: Hide the add new row from the bottom of the grid 3: Remove the grey side bar from the left of the grid For an example see the main grid in the TaskVision Demo at: http://www.windowsforms.net/default.aspx?tabIndex=7&tabId=44 This is the EXACT grid I want. I took a look at the source and I can't seem to find where they made the tweaks. The dgGrid is of type System.Windows.Forms.DataGrid so it is still the basic grid. I'm pretty sure it is something from the class "public sealed class MainFormDgStyle" but I can't seem to find what. -Jason Tag: Component Errors Tag: 51836

    - databinding lose focus Hi, I was wondering if someone could give me a workaround for this... I have a windows form with a number of text boxes that are databound to a datatable. My problem lies in the fact that (to the best of my knowledge) you must tab off of the control (ensure it has lost focus) before it will update the datarow with the information that was typed in the textbox. This is an issue because I give users the option to 'save & close' the form from a menu item, and menu's are specifically designed not to accept focus - thus focus never leaves the control the user was last typing in, therefore the last controls contents never make it back to the datasource. I've tried removing focus from the control programatically as part of the 'save & close' function, but this doesn't seem to work. Any ideas? Cheers, Matt Tag: Component Errors Tag: 51835

And I want to display those GIF image in my picture-box (at first, I want the control to show the first image and a few seconds later, I want the control to present the second image). The following are some ways I have try to deal with this task: - Insert two picture-box control into my form and each control shows only one image; and then, I will toggle the Visible property of them. This is not a good solution if I want to display 10 or 100 images - I make use of ImageList to keep my images. Through it's a very good idea, my animated GIF image stop animating. It's become static image. - Using the Image.FromFile to load image. But I don't want to reveal the images to the user so that they can open,edit them and change my application.

    - ImageList bitmap strip I am attempting to add a strip of images to an image list using the Image Collection Editor. The image strip is a 64x16 bmp and the image size of the ImageList is 16*16. When I add this bitmap it comes in as a single image. Can I use the Image Collection Editor to add a bitmap strip and if so what do I need to do? Thanks, Dan Tag: Component Errors Tag: 51809

    - ImageList image strip Is there a way to load an image strip into an ImageList using the Image Collection Editor? Thanks, Dan Tag: Component Errors Tag: 51789

I am Intermediate VB Programmer. I develop an
application recently which I intend install on a server
network. But when I was testing software on the server, I
encountered a problem(ie when I tried to load the
application on the network from one of the client comptuer
(work-station). It was complaining of Some components
either missing or not properly registered. And these were
some of the component I used for the program such as
MSAdodc.Ocx... Inshort,some most of the activeX component
that I used.
Apart from developing a server and Client
Application,is there no other ways that can make this
applicatio work properly for me while application is on
server system and been accessed from the client computer?
I will be very grateful and thankful, if I can get
the solution right away.

Thanks

Using vb6 I presume? In that case, you're in the wrong newsgroup.
But to answer your question:
An application created with VB6 requires the runtime files, as well as any
ActiveX (OCX) controls to be installed on the users computer.
Installed does noit just mean copied to the users computer - ActiveX
controls must be registered in the computers registry database.
So I suggest you create a setup (A wizard for that is included with VB), and
have all users run the finished setup.
