    - Setting Application directory as path for database. I want to set my application's database path to the directory that the application resides in so that any location I install this application will look to the installation directory, instead of where I have the file located on my system. (ie C:\Documents and Folders\Users\Current User...) I am setting this at design time using the properties window for the OleDb connection. Can I do this? If not how do I do it?

    - 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: CustomEditor on collection for a component 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? I am using VB.NET, with Visual Studio 2003 with all the latest .NET Framework revisions etc. Thank you. Tag: CustomEditor on collection for a component Tag: 51879

    - 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: CustomEditor on collection for a component 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).

    - Client/Server Samples with Business Logic Layer Sorry for the cross-post, but I didn't know whom to ask.. Are there any samples for a true C/S app (preferably VB, but C# is welcomed) with a middle tier using datasets/datatables similar to the the Fitch/Maher sample w/VB6? The only thing i can find on windowsforms.com & MSDN is TaskVision, which is overly complicated for my needs(dont need to expose data via web services). I have adopted the "MS Building Blocks" data access class, but it's only been used in ASP.Net samples, and would like to continue using it in the BLL. Is this possible?

    - Disable MDI Scrollbars Hi all! Relating to an earier post I made. I tried the EnableScrollBar API which didn't seem to work for me. This is how I'm declaring it: [ DllImport("user32.Dll", EntryPoint "EnableScrollBar") ] public static extern bool EnableScrollBar(System.IntPtr hWnd, int wSBflags, int wArrows); Then using it like so: EnableScrollBar(this.Handle, 3, 3); If anyone has any success in disabling MDI parent scrollbars then I'd love to know how you've done it!

    - 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: CustomEditor on collection for a component 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: CustomEditor on collection for a component 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?

    - Image Resource Hi, I have a picture box control in my form and I have 2 .GIF (animated GIF image). 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. Is there better solution ? I have used Visual C++. Using images in C++ is very easy: just insert them into the resource file and display them with. Is there any easy way to use resource in C# ?

    - Control Licensing Help please! I'm trying to implement control licensing using the LicFileLicenseProvider implementation of the LicenseProvider class, but I cannot seem to get the right format either in my <controlname>.LIC file, or in the first line "myClass name is a licensed component" in the file. (I will implement my own validation once I get the basic structure working.) All I can find in the literature is a reference to using the fully qualified name of the control, and the fully qualified name of the component. My control is called ctlAlarmClock and it's contained in a component class called ctlClockLib. So I would have thought that filename = ctlClockLib.ctlAlarmClock.LIC text = "ctlClockLib is a licensed component" should both work. Any help would be greatly appreciated.

I can even add a new item by running an insert query on the dataset and then adding the same item to the listbox using 'ListBox1.Items.Add(TextBox1.Text.ToString)'. The problem I'm having is with deleting an item. Removing from the listbox through 'ListBox1.Items.RemoveAt (ListBox1.SelectedIndex)' works fine as far as the listbox goes, but after having ADDED a row to the listbox I notice that the dataset # ROWS has not changed and when I try to delete an item whose index is higher than the # ROWS in the dataset I get an error stating that that row does not exist.

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?
