'True' Control Transparency - Control With Motion Graphics (simplicity, A 'video Player' Control)
Dec 29, 2010Here's my situation: I have a control with motion graphics (for the sake of simplicity, a 'video player' control) in my project. Think of a PictureBox with constantly-changing images. In front of this will sit a second control (such as a second PictureBox of the same dimensions). The topmost PictureBox will be drawn to in its Paint event.
I need to draw very few elements, and the bottom control is updated much more frequently than I need for this drawing. So these elements are drawn to the topmost control. Think of a news broadcast, where they have live video in the background, with a news channel logo, news ticker, and sometimes gradient visible in front.
I'm trying to create that 'foreground' control, and the closest I believe I have gotten so far is the following:
Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.Drawing.Drawing2D
[CODE]...
The 'Opacity' property in the code above is a sort of "scaling factor." The image drawn to the top control may, in different parts of the image, have any alpha value from full transparent to a full 255. This 'Opacity' property is applied to the entire image being drawn, scaling the alpha values of each pixel.

View 2 RepliesTreeview Control That Works Similar To Apples Finder Control In Column View?
Feb 1, 2012I have a requirement for a new application development where I must present some information to the user for selection via drag and drop. VB offers the TreeView control which would work nice, however the user does not like the Treeview control's presentation. The user wants a control that work similar to the Mac's Finder control while in column view.
Apple's Mac Finder Control works similar to window's treeview. Finder has a nifty view capability that my users would like in some new development that is being done. The finder supports a "column" view. Similar to the treeview, it starts out in a root list. The difference being, when a user makes a selection and clicks on a node, the node doesn't expand, the sub nodes appear on the pane to the right of the list. Clicking on a sub node, will cause the pane to split again and the items within that sub node appear
to the right again.
This will happen again and again with the left pane getting narrower as the user drives deeper into the sub nodes. That is what I am trying to replicate. Obviously, once the user reaches the base list of items, we have to support drag and drop capability. Does anyone know of a control for VB.NET that work similar to the Mac's Finder control?

C# - Prevent Design Mode Enabled Child Control From Being Moved Outside Of Its Containing Control?
Jun 30, 2010I have a UserControl that contains other controls that I would like to be able to rearrange or resize at design time. So I have a custom designer for the UserControl that inherits from System.Windows.Forms.Design.ParentControlDesigner, and I call EnableDesignMode on the child controls from within the designer. That way, at design time, I can drag and drop the child controls to move them, or resize them. But I can also drag and drop the child controls somewhere else on the form that is outside of the original UserControl. Is there a way I can limit the child controls from being moved or resized outside the UserControl?

View 4 RepliesMake Assembly FULLY Trusted - Use The Web Browser Control In User Control
Dec 19, 2009I am trying to use the Web Browser control in my vb .net user control. I am using VS 2008. Finally, I will be calling my assembly (.dll) from a web page. I wanted to display the usercontrol with the web browser control inside this web page. The problem is I cannot proceed since the Web browser control cannot be called from a partially trusted assembly. Using VS 2008 I have created a strong name for my class, also added the <Assembly: AllowPartiallyTrustedCallers()> to the AssemblyInfo. But still the web browser control cannot be seen in my web page. Do you how I can make my assembly fully trusted so that it can access web browser control? If you have used web browser control, can you confirm if this step is really required?!
View 2 RepliesProcess Of Designing A Computer Control Program To Control A HF Communications Receiver?
Jul 11, 2008I am in the process of designing a computer control program to control a HF communications receiver (radio), and have found a problem with the Serial port. I am using VB Express Edition 2008. This module of the program is supposed to take an input string from another part of the program, format it, break it into 4 bytes, and send it to the radio in hex form via COM port 1. The problem comes in when you try to enter a frequency with an 8 or a 9 in it. The 8 or 9 is usually replaced by 45, ex.-input 9900, receiver tune 4545. The exact same thing happens with 8's, input 8800 and receiver tune 4545. All other numbers other than 8 or 9 work fine. The strange part of it is that sometimes the 8's and 9's work, and work correctly. For instance, 900, 1900, 2900, 3900, 4900, 5900, 6900, and 7900 all work correctly. This led me to believe that is may only be when the 8 or 9 is in the first position, but that is not the case, it also shows up in other positions as well. All other frequencies that do not have 8 or 9 in them also work. I ran into this same problem with VB Express 2005, and worked on it for weeks before giving up and going back to VB6.0. This same module (with exception of the port open command) runs flawlessly under VB6. I have even tried importing the MSCOMM control from VB6, but it gives the same results. In de-bugging mode, all of the inputs, decimal and hex seem to be correct, so the problem must come in after you click the command button, but before it leaves the COM port.

Set The Properties Of A Base Control So That Instances Of That Control Inherit The Property Settings
Dec 11, 2009I would like to be able to set Control visual properties such as color, boarder, flat style, etc. on the base class of the control so that as I add new instances of the control, each instance inherits the visual properties of the base. I have tried using Application Settings but it appears as though I need to reference an application setting manually each time I add the control to a form. This is a Windows Form question.

VS 2008 Writing Some VB2008 Code To Control Four 7-seg LED's / Serial Port Control?
Nov 10, 2010I'm writing some VB2008 code to control four 7-seg LEDs I bought from Velleman. They came with some example code in VB 5.0, and with instructions telling me to input 5 bytes at a time in the format Chr$() & Chr$() & etc. for the rest of the 5 bytes. When I try to do this using VB2008, it rejects the $ sign, so I've tried it using the Chr() format, which VB2008 allows. However, it doesn't work. Is Chr() the new version of Chr$() or are they different entities? In sending data to the LEDs, I'm using LiveComPort.WriteLine() as my command. (My serial port is called LiveComPort) I also tried it with LiveComPort.Write() asthe command. I know that my serial port and the LEDs are working, because they respond to the demo program provided by Velleman.

Can a usercontrol inherate an application defined class ie.. could you inheritance a classic rect class into a user control to add the hight and width properties to the control without having to do all the coding all over again? Currently I just declair a private instance of the class within the control and then encapsalate. It would be nice if I could just inherit all the functionality of my classes into controls designed to implament the classes.
View 1 RepliesOrder Of Creation Or Adding To The Parent Control Determines Whether Or Not A Control's Dock Property Supersedes Another's

View 2 RepliesMake The Controls Stack And Fill Up The Available Space Left By A Control If The Control Is Hidden Or Removed From The UltraGridBagLayoutPanel?
Sep 8, 2011I am wondering if anyone has any idea how to make the controls stack and fill up the available space left by a control if the control is hidden or removed from the UltraGridBagLayoutPanel.
Example:
[Textbox 1]
[Textbox 2]
[Textbox 3]
[Textbox 4]
[Textbox 5]
If I hide [Textbox 3] as of now, it will disperse the space left equally and pad the remaining text boxes with the space. However, I would like it to do this...
[Textbox 1]
[Textbox 2]
[Textbox 4]
[Textbox 5]
Where all the text boxes will move up and [Textbox 4] will completely consume the space left by [Textbox 3].

Asp.net - Adding To Page Control Collection From Inside A User Control?
Feb 12, 2011I have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs. As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup.
The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using. ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False) which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."

Bind Control.Text Property To Control Position In FlowLayoutPanel?
Jun 6, 2012Is there a way to bind the text property of a control to an expression? I have a user control that I add to a FlowLayoutPanel. You can see I have 4 controls in the FlowLayoutPanel below. The first control is a LinkLabel and the other three are my user controls which are numbered 1, 2, & 3. I'd like to bind the label that shows the 1, 2, or 3 to the user controls index within the FlowLayoutPanel.
If I happen to remove the 2nd user control I want the 3rd user control to now display 2. I could use the FlowLayoutPanel ControlAdded or ControlRemoved events, but wanted to see if I could do some binding first.
Bind Property Of User Control To One Of The Parent Control's Fields?
Dec 30, 2011If I need access to the value of a user control's property BEFORE PreRender, would I need to base the custom control off of one of the preexisting data controls (repeater, listview,etc.)?One of my user controls features a gridview control that is configured based on the user control's properties on which it resides. Several of the key properties alter the SQL Statement for the underlying recordsource. I'm now in a situation where the property that sets the WHERE statement for the SQL Statement needs to tied to a value in the user control's parent FormView. Think of the formview as displaying a customer detail record. The user control takes the customer's account number and then displays data from a related table such as Customer Contact Names. Since the gridview is created before the control's prerender event, working within the prerender event doesn't seem efficient.
