• VB.NET custom user control graphics rotation

  - by AtharvaI

  Hi, this is my first question on here. I'm trying to build a dial control as a custom user control in VB.NET. I'm using VS2008. so far I have managed to rotate image using graphics.rotatetransform . however, this rotate everything. Now I have a Bitmap for the dial which should stay stable and another Bitmap for the needle which I need to rotate. so far i've tried this: Dim gL As Graphics = Graphics.FromImage(bmpLongNeedle) gL.TranslateTransform(bmpLongNeedle.Width / 2, bmpLongNeedle.Height * 0.74) gL.RotateTransform(angleLongNeedle) gL.TranslateTransform(-bmpLongNeedle.Width / 2, -bmpLongNeedle.Height * 0.74) gL.DrawImage(bmpLongNeedle, 0, 0) As I understand it, the image of the needle should be rotated at angle "angleLongNeedle" although i'm placing the rotated image at 0,0. However, the result is that the Needle doesn't get drawn on the control. any pointers as to where I might be going wrong or something else I should be doing? Thanks in advance

• Very long tree control inside a <frame>

  - by ryancerium

  I have an tree control inside of a frame. It's quite tall, around 2000 pixels. Right now, we use the frame's scroll bars, which is mostly good. Unfortunately, when you select an item near the bottom of the list, the page reloads and the view goes back to the top of the list. I tried calling the tree control's ScrollNodeIntoView() function, but since we're not using the tree's scroll bars, it just thinks that it's displaying the full 2000 pixels and the control doesn't have its own scroll bar. I'm not much of an HTML guru, so I have two ideas, neither of which I know how to do. 1) Tell the frame to not to let the tree render all 2000 pixels and instead stay inside the viewable area. 2) Tell the tree to not render all 2000 pixels and instead stay within the viewable area. Setting the CSS height property on the within the frame doesn't do anything. Thanks.

• How to change position of inherited items in an Inherited user control

  - by Yalda

  I have used a user control as a base class (let's call it BaseUC) with 3 labels (in 3 lines) on it (they are set as protected). And there is another user control that inherits from it (InheritedUC). I have added two more labels in InheritedUC, which are positioned between the base's labels (so there are 5 lines). Everything is fine is Visiual Studio's design UI view. But when I run the application, labels on BaseUC overlap with the ones in InheritedUC and I can't see the ones on the inherited control. Any ideas to fix this? Thank you very much

• Find a control by String from asp.net Web service

  - by jphenow

  Well since it seems relatively difficult to send the object of a WebControl over JSON using jquery.ajax() I've decided to send the name of the control as a string because I know how to do that. Then I promptly realized that, from a web service, I don't actually know how to search for a control by ID name. Since its a service I can't seem to get Control.FindControl() to work so does anyone have ideas or suggestions? All I'm trying to do is call a databind() on my radcombobox. Thanks in advance! For any of you that knows anything about asp.net/rad controls - I'm basically updating a database and want the radcombobox to be in sync with that database again after adding something, before I autoselect what was just added. Other than databind do i have to call anything to refresh that list? Thanks again!

• Referencing control on one form from another form VB.NET

  - by Tom

  My gosh man, why is this so complicated in VB.NET? As you can guess, I'm kind of new to .NET and just want to reference a control on one form from another. Usually I would just do Form.Control.Property but that doesn't work and every example I've found through Google doesn't work for me. It just seems overly complicated with public classes, etc. Is there a more simpler way to do this? I'm ready to throw in the towel and just use a global variable at this point. I have the form containing the control I want to reference, frmGenerate which has a textbox called txtCustomerNo. From this form through a button's click event I want to show another form, frmCustomers, and have that form reference the value in txtCustomerNo. frmCustomers.ShowDialog() It has to be something simple that I'm just not grasping. Thanks.

• Advice Needed on Development of ConnectionWizard Custom Control

  - by SidC

  I have the need for an ASP.NET custom server control that will check the web.config file for a connectionstring name, prompt the user to create said connectionstring if not present, and execute create table stored procedures using the connection. This control will be embedded into a webpart for use in a WSS3.0 solution. Can anyone suggest some good tutorials on creating this type of control - specifically addressing use of connectionstrings? What methods/classes do I need to setup? Should I use the p&p data application block for this project? Thanks, Sid

• How to expose a control collection to a property grid at design time

  - by Stefano Delendati

  I have a custom control that with a property that is a collection of custom object. This custom object hava a reference to some component/controls. When at design time I tray to add an item to the collection and select the object, VS tells me that the control is not serializable.

• Custom Control Events in C#

  - by pm_2

  I'm trying to create a custom control and need to raise an event from it. The idea is to raise an event at the end of the click event (OnAfterClick). I found one or two tutorials on doing this, but am clearly missing a step somewhere; I have the following. In the control: public class AfterClickEventArgs : EventArgs { ... } public partial class MyButton : CommandButton { public delegate void AfterClickEvnt(object sender, AfterClickEventArgs e); public event AfterClickUpdatedEvnt AfterClick; } protected override void OnClick(EventArgs e) { ... Processing here ... AfterClickEventArgs myArgs = new AfterClickEventArgs(); AfterClick(this, newArgs); } In the program using the control: In InitializeComponent(): this.MyButton.AfterClick += new System.EventHandler(this.cmdMyButton_Click); This line is giving me a compile error (cmdMyButton_Click does exist). It tells me: Cannot implicitly convert type 'System.EventHandler' to 'Namespace.MyButton.AfterClick' Can anyone tell me what I'm missing, or misunderstanding about this, please?

• How to Get Control Panel Categories (Groups) on Windows Vista and Windows 7

  - by Bill

  Is there a way to get a listing of control panel categories on Windows Vista and Windows 7 using the shell? Is there a way to determine which category an applet is assigned to using conical Names using the shell? such as Microsoft.Mouse is in which category? I have some code that works nicely to display control panel applet names obtained from the shell in a TListView in a Vista Classic ungrouped list. I'd like to try to group the applet names in the TListView similar to Control Panel Classic Grouped by Category in Vista. Bill

• Enableeventvalidation in web user control

  - by Khushi

  Hi, i have a web user control containing a repeater. The repeater contains three buttons. On button click it gives the following error : Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" % in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. Since user control does not have page directive, so i changed the enableEventValidation to false, but it restricted the itemcommand event of the repeater. Can someone guide me, how to solve this problem?

• What control to use

  - by Tarscher

  Hi all, I have a list of devices that I need to filter on according to options selected by the user. One such option is cooling: when the user selects cooling only the devices with cooling are shown. If cooling is not selected then all devices (with or without cooling) are shown. I wonder what kind of control I best use for this. My feeling is thata checkbox is not a good control since it represents: No cooling (unchecked) / only cooling (checked) while I want cooling and no cooling (unchecked)/ only cooling (checked). What control is best used here? Thanks.

• Access dynamically generated control from code behind

  - by user648922

  I load a piece of html which contains something like: <em> < input type="text" value="Untitled" name="ViewTitle" id="ViewTitle" runat="server"> </em> into my control. The html is user defined, do please do not ask me to add them statically on the aspx page. On my page, I have a placeholder and I can use LiteralControl target = new LiteralControl (); // html string contains user-defined controls target.text = htmlstring to render it property. My problem is, since its a html piece, even if i know the input box's id, i cannot access it using FindControl("ViewTitle") (it will just return null) because its rendered as a text into a Literal control and all the input controls were not added to the container's control collections. I definitely can use Request.Form["ViewTitle"] to access its value, but how can I set its value?

• Running control.exe as process does not WaitForExit()

  - by Lisa Alliss

  I am running control.exe as a process. (Windows 7 OS, .NET 3.5, C#). It does not stop at WaitForExit() as expected. It immediately "exits" the process even though the control.exe window is still open. I have tried the process.Exited event also and that is triggered before the application exits as well. Here is my code: Process process = new Process(); process.StartInfo.FileName = @"c:\windows\system32\control.exe"; process.StartInfo.Arguments = @"userpasswords"; process.Start(); process.WaitForExit();

• Using AuthzSVNAccessFile for controlling SVN Access produces HTTP 400 Bad Request

  - by meeper

  I have a new repository on an existing subversion server that requires us to perform path based authorization within the repository. I found that the AuthzSVNAccessFile directive in apache is directly responsible for allowing this functionality. After fixing several other problems such as AuthzSVNAccessFile preventing SVNListParentPath from operating properly, I am left with one single problem. I can checkout, I can update, I can commit, BUT I cannot execute an SVN COPY for performing branch/tagging operations. The moment I comment out the AuthzSVNAccessFile line in the Apache config everything works as expected except the obvious path authorizations. Versions: The server OS is Debian 6.0.7 (Squeeze) Apache 2.2.16-6+squeeze11 Server Subversion 1.6.12dfsg-7 Clients are running windows Clients tried are: TortoiseSVN 1.8.2 Build 24708 64bit SVN CLI Client 1.8.3 (r1516576) Authentication is performed via AD to a Windows 2003 domain and appears to be operating normally.

I have also confirmed that all files for the repository (/var/svn/authtestbasic) are owned by the Apache user www-data.

• Router behind router network setup

  My relative has bought a router instead of a switch which causes remote-access control issues on his network. His existing network has a 1st router where all PCs are connected via LAN cables. The 2nd router connnects to the 1st router and the remaining PCs are connected to the 2nd router via LAN cables. Normally, I would perform remote-access to help him out with some task. Now it seems all services behind the 2nd router are unavailable to me. How can I resolve this issue?

• Aruba Wireless Controller 200 and AP70 manual

  - by techie

  I have an Aruba wireless system that is currently in use but there is no documentation from the previous person in charge. I have no manuals or login information for the wireless controllers and APs. I checked the Aruba website and you need to register to access the support information but registration isn't instant and takes several days. I've waited for quite a while now and have tried googling and checking the Aruba forums but have found no indication of a manual. What I really need is the ability to reset the controller and APs so I can access the device with the default username and password. There is no reset button on this device so I have no idea how you go about resetting the controller and APs. Hm it seems I can't create a new tag as a new user. If possible can someone add an "Aruba" tag?

• Allowing Remote Connection in IIS on Windows 7

  - by GiddyUpHorsey

  I'm trying to give access to a website in IIS on my Win 7 machine to another person on my network. He's unable to access it. I was wondering if perhaps it was because IIS isn't configured to allow remote connections (I seem to remember having to do this sort of thing on Win XP). I've hunted around in IIS and googled but am not finding a way to configure remote connections on Win 7. Some of the answers I've found seem to refer to Win Server 2008 and talk about a management service in IIS Manager, but it doesn't appear to be present on my machine.
