I have a user control in vb.net application.and i have a form in vb 6.
so in my vb.net applciation to this user control i need to mention the vb 6 form as its parent.
Means when i run a vb6 application i should see this user control as a part of that form.
Im Using VB 2008. I have MsgBox() statements in all Mouse & Form Click events to TEST & NOTHING FIRES during Form Load when I click on Form or Button Controls !!! The Form Load event contains code for Displaying the Label.Text control many times with changes in the Text to simmulate annimation.

I'm using the VS 2010-Net 4.I have develop an usercontrol that is compiled on one DLL and when I reference this DLL in other applications the usercontrol doesn't look like it was desined. It looks all wrong.
In the same project of the usercontrol if I put the control inside of a form there looks the way it supose to but in other projects as reference doesn't.
I have a customer which as a Visual Basic Project in single instance mode with a wired presentation logic.
The main form contains a TabControl with mutliple TabPages.If I click on TabPageA another form is shown in front of the Form and resized to have the same size as the TabPage.
If I click on TabPageB the first form is hidden and another form is displayed.So basically for the user it looks like you have a TabControl with different TabPages which is not the case.
I tried converting the Forms to UserControls and put them inside the TabPage, but, thanks to the SingleInstance app, this would take a whole lot of refactoring. I tried it but eventually gave up because of many many runtime errors and I don't want to put any more effort in this.
Am faced with the above problem which I have failed to understand. the details of the error are given below.

I have a DataGridView in one of my form which at a certain point I resize an change it's position. I would like to be able to restore it to the designer's default position at runtime. I know I could save it before changing and then restoring it later, but I feel like there surely is a way in .NET to just restore a control position to it's default.
View 2 RepliesI am developing a software using microsoft visual studio basic 2010. I used a datagridview control to display a list of data from product table. What I want to do (actually I am not sure how to do it, or is there a way to do it), when I choose one of the value in one of the column inside the table, I want it to open a form that contain data(details) based on that value.
How to do it? How to call the value that I pressed, so it can be used to open a new form containing the details of that value
Example of the data: (the "system" column) SYSTEM
topaz
nex1300
Nec
If I pressed "topaz" system, it will prompt me to a new form containing the details of that "topaz" system.

I am making an invoicing application. I have a label (lblCost) inside of a UserControl (InvoiceEntry) inside of a FlowLayoutPanel (pnlEntries). InvoiceEntry represents a line item on the invoice, and pnlEntries is the "body" of the invoice. pnlEntries can hold several InvoiceEntry controls.
I am attempting to sum all of the lblCost values from each InvoiceEntry control to make a subtotal, and I want that subtotal to change automatically if costs are changed (e.g., a change in quantities being ordered). Is there a way to handle when the lblCost.Text property of any of the InvoiceEntry controls contained within pnlEntries changes?

View 4 RepliesI 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."
How are you supposed to add controls to the pages control collection from inside a user control?
I have created a user control and am able to add it to a page with out any problems, but how to I reference a control that is inside of the user control For example if I have a text box inside the user control and want to set the text property through code or get the text property, How can I reference the control inside the user control. I have tried a few different things but nothing seems to work when I type the usercontrolname.control.property I just get an error.

I have a UserControl.ascx which essentially outputs the Name and Email of the user currently logged in (stored in session variables, for the record) at the top of every page on my website. Said control is currently called by Site.Master using <%Html.RenderPartial("UserControl")%>.
It works fine when I log in for the first time and my details are displayed correctly, but when I log out and try to log in again something strange happens...
The Control itself tests the condition Session("auth"), which my controller sets to true upon authenticating a user and which it forces to false when the logout button is pressed. All session variables are cleared upon logging out.
(For the record, my user control used to check Request.IsAuthenticated rather than Session("auth") to determine the current Session State. The same issue arised.)
The problem is that when I try to log in as a different user, instead of showing the new user's information in the header, nothing appears beside Name: and Email: (see code below). I suspect this is because UserControl.ascx is not updating its state.
Ideally, I'd like a solution which would force UserControl to check Session variables every time a page is loaded. Is there a clean way to achieve this?

I have just turned to using VB.net and would like to know why when I load an RTF (with tables in a 9x9 cell format) all appears in a 1x9 format...i.e. instead of loading the tables (some are side by side), they load up in series (below each other).
