[2008] Usercontrol Rendering On Wrong Control?
Jan 18, 2009
I've built my first usercontrol for use in a GPS Mapping forms app.
pic1 shows "panel1" containing some picturebox "tools" with a map(another panel containing a picturebox) underneath.
Pic2 shows that I dragged the map and the "tool" have not moved with the drag.
"panel1" also contains my usercontrol( this will show a transparent map scale). My usercontrol and all the "tools" definately have the same parent - ie "panel1".
If I resize the form to cause a re-paint of all the controls I get Pic3 - the red T bar (my usercontrol) will be the map scale.
Everything looks OK until I drag the map - the user control goes with the drag. Pic4 shows that the usercontrol image has been erased as it passed under the "tools".
I don't understand why the "tools" stay put and on top of the map and the usercontrol does not - even though they all have the same parent.

I am using a server report, which I am rendering in VB.net using reportviewer.serverreport.render into a PDF document.Strangely, when i do this the text in my graphs is really small compared to in the designer or when I view the report in a web browser.

I have a web application that works in our stage/test environment fine but once we moved it to our production environment something weird happens. All the control ids change. a label went from ctl00_cphMainContent_lblPetName to _ctl0_cphMainContent_lblPetName. Why would this happen? What could cause something like this to happen. The only two differences I know of are the production environment has HTTPS and I've disabled debugging.

I've pulled down a webpage using a WebRequest object, and need to parse it, but first I need to render it since there is scripting on the page. I don't want to use the WebBrowser control because that forces me to jump out of my current function to the DocumentCompleted event, and "lose my place" (so to speak). Is there any way for me to pull down a URL using a WebRequest object and have the page rendered but still stay in my function?

I can't seem to find a way to use the IE9 rendering engine in the WebBrowser control, instead of the IE7 rendering engine, using Visual Studio 2010 and Windows Forms.

I tried this registry below and it didn't work. My application name is 'Testapp', using VS2010 on windows 7 with IE9 installed. I want to render the pages in IE9 not IE7. [URL]used this registry below, by making one separately then registered in registry. After that I launched my app but it still loaded in IE7.
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftInternet ExplorerMainFeatureControlFEATURE_BROWSER_EMULATION]
"testapp.exe"=dword:00002328
how can I use IE9 as render instead of IE7.

Dim tabnum As Integer = mycontrol.TabIndex
If My.Forms.Sessions.GroupBox1.Controls(tabnum).Enabled = True Then
mycontrol.ForeColor = Color.Red[code]....
I have checked and double checked the tab order on the controls and run traces with debug. The control found in my.forms. sessions. groupbox1 seldom returns the proper tab. Using a 'watch' I can see the tab names and the tabname (my.forms.sessions. groupbox1. controls (tabnum).name is often the incorrect one.

I ran into a situation where FindControl was returning a control that wasn't a complete match of the Id I was searching by. There are two controls in the parentcontrol with similar Ids like: "MyControl" and "MyControlAlternate". When I call FindControl("MyControl") the control returned is "MyControlAlternate". I was wondering if anyone had any explaination why or thoughts as to what might be causing this problem. The way I got around this was implementing my own version of FindControl.

I am trying to make a graphics program with mousewheel-controlled zooming using GDI+. My plan is to provide rapid feedback, such as a low resolution render or even just a bounding rectangle, followed by a full resolution render as soon as possible afterwards. It seems logical to me to try a BackgroundWorker for the latter task. This is my first attempt to use one of these, or any other way of multithreading for that matter. Mousewheel events can follow one another much more quickly than I can render to the screen. That means I need to kill any rendering process that is already running and start a new one with the latest value of the zoom scaling factor.[code]The above class coexists with a DrawingSurface class, a UserControl which listens for the ProvideFeedback and ScaledImageReady events and paints the image accordingly. It also raises mouse/keyboard events for the zoom and other tools to deal with. My problem arises in the DO loop waiting for Cancellation to finish. The zooming routine works for one or maybe half a dozen renders, depending on the image size, but then it hangs in that loop and never comes out.

I'm trying to include a user control in an aspx page, it works fine, but my control does position itself where I want it and always appears at the very top of the page. Could it have something to do with the masterpage? I've tried registering the user control in the master page, but I don't know how to reference it in the content page.[code]

I've got a DataGridview I want to remove columns from as it greatly increases performance when I format the DGV. The first time I remove columns in a loop (using the removeat) property, everythings fine. But when I try to remove more columns in another loop, it appears to remove the wrong columns and displays the wrong data. In other words, it displays the wrong data and headers; and the columns it does show has headers and cells that don't match.

I have this database and I need to load it with a visual basic form in Visual Studio 2005.The database has 6 tables and they contain wrong data that I must filter when loading the database in the form.
A quick example:First table is Category, which has 3 fields (id, name, description). In one record I have 2a for id (a numeric only field) and in other record I have m1lk for name (a string only field).
When I click a button I load the database into a DataGridView control. How do I stop visual basic from loading into the DataGridView control those records that have invalid data (like in my example).
I have try with SQL queries using WHERE and LIKE, like in
SELECT IdCategoría, NombreCategoría, Descripción
FROM Categorías
WHERE (NombreCategoría LIKE '[!l]%') AND (IdCategoría LIKE '[!abcdefghijklmnñopqrstuvwxyz]')
but it's really difficult to filter things like Angel* and P3ter and Hood8, all at the same time..

I'm working on my second project; a layered image displayer.
It works like this:
- The user adds a new "image layer"
- The user can set the texture, image, size, rotation and color
- This all can be done using a selection square and some dialogs
It all works fine, but I found that there is one thing still unclear to me:
- Can you render layers without totally starting over (refresh) on every change?
As example, I have 200 image layers. I change one image layer somewhere in between them, and the program has to refresh all those images. (1 - 200)
This takes awfully long.
Now I found a small solution; I gave all layers a "finalimage" so it can render a single layer. Next I used, in the program, a back, active and fore layer. This way the program only has to render 3 images when changing the "active" layer. When you select another layer, all 3 layers will refresh. (with all those 200 layers).
Here is the code to get an idea:
Dim OLDINDEX As Integer = -1
Dim BackLayer As New Bitmap(800, 600)
Dim ActiveLayer As New Bitmap(800, 600)
Dim FrontLayer As New Bitmap(800, 600)
Public CurrentIndex As Integer = -1
Public PerformGlobalUpdate As Boolean = False
[Code] .....
It all works fine, but the only problem now is that it takes ages to select a different layer.

is it add control to a form and add control to a usercontrol is using same method like me.controls.add(newpanel)?im a little bit confuse here because that way is not working. im trying to add a panel, to a usercontrol at runtime. the usercontrol is also added at runtime. for e.g. i have click add bar menu, than a usercontrol appear. then, when the usercontrol is selected and i click on add note menu, it will add a panel that contain labels to the usercontrol. this is what i have done. the 'me' is the usercontrol and i put this code under that usercontrol load event.

I have a WebBrowser control in a VB.NET WinForms app. I am able to set the default printer from code and print without prompting the user. However, there is also a print button that shows the PrintDialog. If this action is done first the page will print.Then if I try to programmatically print later (again setting the default printer to some other printer) the it will print to the last printer selected in the PrintDialog box even though I am resetting the default and see the default printer being changed in Windows.It works fine unless ShowPrintDialog has a printer chosen first. Once that occurs it seems to always use that printer no matter what I do.
For Each strPrinter In PrinterSettings.InstalledPrinters
If strPrinter.Contains("My Printer") Then
wScript.SetDefaultPrinter(strPrinter)

VB.NET 2.0 Framework..I developed a control that implements IExtenderProvider in order to attach to controls and display a form for translating of the text of that control.This works great on regular controls on the form but the IExtenderProvider is not attaching to controls on UserControls by default.Is it possible to modify the UserControl or my IExtenderProvider control to enable it to attach to controls on a UserControl?

I have Visual Studio 2008 SP1 installed and lately it is taking longer and longer to bring up a Resource File (.resx) in its standard editor. Some of the file loads up, but you can see that the screen does not paint/render it 100%.I tried doing some searching on the web and the only thing I came across was doing a edit to the GDIProcessHandleQuota registry entry from 10,000 to 20,000. This appeared to work initially, but the problem came back the next day.I am doing an extensive localization project and this is severely limiting the amount of work I get done.

Public Shadows Property Enabled As Boolean

Return _Enabled
End Get

I have created a usercontrol that contains two rectangle shapes to create a unique button effect and a rounded-corner rectangle shape serving as a border to provide a look similar to a group box. It also contains two labels, one for use with a Text property of the control and the other to indicate the status of expansion of the control. The control is designed to collapse itself when the "button" is clicked leaving only the "button" visible. Clicking it again toggles this affect. I've dubbed it an ExpansionBar. It is also designed to be a container control so that I can add controls to it and allow these to disappear when the bottom portion collapses. The problem is that the controls contained in this usercontrol cannot be accessed during runtime. In other words, I can add a checkbox to it and it will disappear correctly when the control collapses, but I can't select the checkbox to check it... same thing with any other controls, you can see, but can't touch. I'm a novice developer, so I'm sure I'm missing something obvious.

I created a server control which consist only of fews buttons.
CWNavigation.vb
<ToolboxData("<{0}:CWNavigation runat=""server""></{0}:CWNavigation>")> _
<DefaultProperty("Id")>[code.....
I then referenced it in my ASPX page. Take note that the control are in the same solution, same project located in Commun/Navigation/CWNavigation.vb.
<%@ Register TagPrefix="NAV" TagName="CWNavigation" Src="~/Commun/Navigation/CWNavigation.vb" %>
I added it to the page.
<NAV:CWNavigation ID="CWNavigationService" runat="server" />
But the designer file along with the code-behind generate it as.

I have a Windows Form frmMain() holding seven more-or-less unrelated UserControls, ucFlopsy", "ucMopsy", "ucCottontail", etc...I say "more-or-less" because each of the seven UC has three similar public read/write properties:
IsLocked (a boolean indicating if the following two properties are "Locked")
IsLockedID (if IsLocked=True then IsLockedID is an integer)
IsLockedName (if IsLocked=True then IsLockedName is a string)

I had a default Icon I set for my windows form app in the properties section of the form. Since then I have changed to Icon. However, on the Task Bar at the bottom of the screen, if there is more than one form opened and Windows groups them together it displays the old icon image next to the group name. How do I change this to display the new icon image?If I go into the Application settings in the properties of my windows form, it has Icon: of the new icon file. I have changed it here and on the forms themselves. Still, the old icon shows up!

I have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500. To see what I am talking about, create an empty "Windows Forms Application" project and insert the below code into it.

nserting values from a datagridview into an access db. However the values are wrong. As you can see in the code, I've made variables to check what values are fetched from the datagridview, and those values are correct. But in the db there are other values. What's going on?The thing is some of the fields are run-time-created comboboxes and there are also datagridviewcheckboxes. But like I said, the values in the t1...t7 variables are correct.
