Whenever I switch tabs in my tabpanel.for example when switching from 'armory' to 'Mystats'.You can clearly see there's a serious delay in drawing the containers, textboxes, pictures.. The 2 backgrounds of the tabs are different and the Mystats tab has several very small images like 1kb each about 24 of them ).PS: at the moment of the screenshot the upper half is of the Armory tab and the bottom half is of the Mystats tab.
View 2 RepliesI know that time delays have been covered before around almost everywhere. however a method that forgoes forcing the GUI to become temporarily non-responsive, is all but a myth, or at least to my findings. i have the need for a GUI program to delay before the next command, however using the current method, detailed following, it causes the desired effect however it dose make it much less polished as when you click anything else on the GUI it goes un-responsive for the directed time. [Code] make a sub called say Tdelay( milseconds as integer) and have it run a loop as many times as the milseconds variable indicates and each time making the thread delay for 1 milsecond and then update the GUI/form in some way, then re-loop.

Winforms, VS2008 I have a mainform that has 2 usercontrols: UC1 and UC2.UC1 has a treeview with treenodes. UC2 has tabControl with few tabPages. Selecting different nodes displays different details view in the TabControl's TabPages. What I need is canceling the event when the user has selected a node in the treeview, then he selects another node (i want to be able to cancel this last event:selecting another node, all depending on a certain logic)I mean: When the user is working on a tabpage in the tabControl, when he clicks on a different node in treeview (different from the currently selected node), before displaying the new node's details in the TabControl, I perform some logic, then depending on that logic, I set
e.cancel = true in the UC2 Validating event handler. (Rememebr UC2 includes the TabControl and the user, supposedly, has the focus on a control somewhere in TabControl)
But mysteriously, the event gets never canceled and the user still moves to the next node, displaying its details in the TabControl, although I set e.cancel = true.

View 2 RepliesI need some code to draw a resizable, draggable rectangular cursor (or selection box) on a picturebox. I found some excellent code (albeit rather old) that does just that, but on a form rather than a picturebox. I have tried converting the code - basically moving things to the picturebox events (Paint, MouseDown, MouseMove etc). It nearly works but leaves a trail behind it when you move or resize the cursor. In other words, the selection rectangle is not being erased before being drawn in the new position.
Is there some fundamental difference between drawing graphics on a form and drawing on a picturebox that would cause this behaviour? Something like, when you invalidate a form and cause a redraw it erases what you did last? If not, then I just need to dig a bit further and work out how the cursor is being erased from the previous position.
Here's the original code that works fine on a form:
Private DragRect As New RectangleF(20, 20, 100, 80)
Private Adornments(7) As RectangleF
Private MouseInRect As Boolean = False

Say I have 3 Buttons, labelled: Unit 1, Unit 2 and Unit 3. When I click on any button I want a drawing of that unit to appear on screen at a pre-specified starting point.

i'm developing an app where i'm reading a value from a device and putting it into a mysql db, i have setup a function where the vb will calculate whether the new value being read has changed by 3% from the last value and if it has run the mysql query. What i need to do it read the value into a variable, then a new value and compare the two with the % function, how do i read a value and maybe add a delay before reading the new value (and it being overwritten) and doing the calculation?

View 2 RepliesI would like to enquire how I can set a delay in between chunks of code.For example, after some code which interacts with a server, I am supposed to get a corresponding information from the server before it is appropriate to proceed on to the next part of the code. As the server response is not immediate, therefore an arbitrary delay is needed.What is the proper code format that I need to add?
View 7 RepliesI am dealing with a web application that includes VB.NET (UI) & VB6 middleware (DLLs).One of our installs, a Win 2003 Server/IIS 6 environment shows a 2 minute delay after the application login page.The application has been added to Trusted Sites & is not in a DMZ. It uses Forms authentication.
I am looking for ideas on what might be causing the delay. The code is difficult to access and I would like to leave that as a last resort. I realize it's not much to go on but I am hoping someone here has run into a similar problem.

My dilemma: I have a POCO: "ReportSource" that is generic. I have a user control wrapping up some report building logic. My user control defines a ReportSource property but it will ultimately be the job of the page that calls the user control to assign that ReportSource property. How can I define the property in my user control without specifying a T? Btw, I tried (just for larks) to make the user control generic... That ended badly. public ReportSource<T> ReportSource {get; set;} (Note that I've tagged this as C# and VB.net... C# is my norm, but I'm having to deal w/ legacy.
View 2 RepliesNow there's a user "A" who has 100 followers...now what i want to do is whenever user "A" submits an article in the website all his followers should get an email with the article link...that is okay i can do it.
Problem: Now, there's a submit button on the page which stores the article in the DB and sends email to the followers...as there are many followers it takes a lot of time sending the emails...so the page keeps showing loading msg till all the emails are sent..how can i send all the emails asynchronously ??
i mean after the article has been submitted ...the emails should go automatically to the followers without putting the email sending function in the click event of the button....hope am not confusing you folks.
can i do something like store the article in the DB , redirect to the article page , start sending emails in a batch of 10 per 10 mins automatically...this process should start as soon as an article has been submitted by an user.
