VS 2010 Waiting For A Screen Re-draw To Finish Before Continuing?
Oct 16, 2011
I'm writing a simple program that takes a screenshot of tab1 of the GUI, then takes a screenshot of tab2, then tab3, etc. I've got the screenshot code down pat, but the problem with my current code is that it's taking the screenshot of each tab before the screen has a chance to fully redraw, so the resulting images are screwed up.Is there a way to get the program to wait for each tab (and all the controls in it) to be fully visible before each screenshot is taken?I'd like to avoid using a timer for this, as the screen redraw speed will vary depending on the user's computer, and the contents of each tab, etc.[code]
But I need to wait for it to wait before letting it to go on to the next thing like clear cookies, which would be: Shell("RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 2")
I need to let my webbrowser finish loading before continuing. the problem is, i have the stuff that needs to be done in a do loop, so i can't use documentcompleted.
i currently have
Form2.wb.Navigate(url) While Form2.wb.IsBusy = True 'do nothing End While
to check if the webbrowser is loading, but it doesnt really work.
I am trying to make a marquee progress bar run while my long function is running. When the function is done running, I want the progress bar to disappear.
[code]...
If I don't do t.Join(), the progress bar disappears right away and then the thread runs. If I do Join(), the progress bar doesn't appear until the message box pops up after the thread is done!How would I get the effect of the progress bar running while the thread is running and then stopping when it's done?
Is there a way of stopping the main page waiting for a usercontrol to load before it can finish loading?
I have a usercontrolthat has to do a lot of DB calls which can take a few seconds making the page slow to load. Ideally I'd like the main page to load straight away and then the usercontrol content appear when it is ready.
In my DoWork() function I register with our sip server. Then I have to wait for a response back. However, the response I get is received in another event. However, before I am able to check the flag in the DoWork() the DoWork() has all ready finished and the response comes after.
I am trying to find a way to wait in the DoWork() until I get a response in the Diagnotic event. I have a global flag that is set in that event that I have to check in the DoWork().I was thinking of maybe blocking in the DoWork() until the other event is finished. Maybe using a join.
' Do work in background worker 'Will return less than 8 if there are no error message from the library If (Not Me.bgwProcessLogin.CancellationPending) Then ' Register and wait for response
I have been tasked to do a project, and have been given a list of links from the client - what the Project needs to do is:1 - open google with a specific search phrase - no problem2 - look on that page for any links containing any member of the list of links, if found, invalidate the entry in the list, and auto-click the link, then go back3 - repeat for any other "finds" on that page4 - when done, auto-click on "Next" (no problem) and go back to step 2For now, I am not even attempting to auto-click the found link and go back, I am just listing all found links in a TextBox. The problem I am having is waiting for the next pages to load before looking for a match in the list of links. I tried using webBrowser.DocumentCompletedto set a Boolean - I tried testing WebBrowserReadyState in the DocumentCompleted event ar the code below gives the best results but it is inconsistent, meaning it completely misses some pages that I know have links on them that match.
I would like to execute an external program within powerpoint after the presentation has loaded so i can see if its working. In short my overall objective is to execute the external program which will open up the command prompt and use the sendkeys method to sendkeys to command prompt which help it to run a script at the correct time (which is after presentation is loaded).
Do Until WebBrowser1.IsBusy = False Application.DoEvents() Loop
or use the WebBrowserReadyState however, this doesnt seem to work after I invoke a member For example, I use "invokemember("click")" and then after that, use the WebBrowser.IsBusy or ReadyState, and do another InvokeMember, it doesnt work. It seems after I invoke a button and it navigates, it doesnt seem to matter?
I send a message a while ago and no one answerd, how can I draw directly on the screen (not on a specific window) just on the screen, neither if it's on the desktop or anything else.Is there is any option to bring up the switch between applications window (Alt + Tab), I don't want to use sendkeys because the user need to keep the key down and I just want the user to select the application with his mouse.
I have a button in my application that starts a function to play sounds. But when the function starts a have a problem that my application stops working until all the sounds are played. Then a want to display a waiting screen to show the status of the current application. To this i thought to create a new thread to open the waiting window and then show the messages. But i have a problem that when my thread finishes, it closes the waiting screen. I tryied to put a loop inside my thread, but this crashes my aplication until the loop condition is satisfied.
making verified accounts for my marketing and now I am hooked into improving as it is turning into a very good program I am just stuck with one thing which I can see being a very simple solution but I have search forum after forum and tonnes of Google searches all worded different to solve my my.It really is simple at present I use different buttons to automate different parts/pages of the account creation I am now setting it up so I click say for example a "go" button and it fills in the first page (and heres where I'm stuck waits for a specific url or even just a new url to load before continuing with the next bit of code
asking something like this i know it get's asked alot but i haven't found any code for this or i didn't look good enough. My internet is super slow so it is hard to browse the net , Anyways i want to draw on the screen just like when you draw on your form with graphics how would i accomplish this ? if anyone could provide some code or a link that shows a little about it that would be great,
I've inherited a project in VB6.NET 2008. There is a Panel control where graphs are drawn along with titles, axes, legends etc. What is drawn on the panel is also printed WYSIWYG (on a print command, of course) The problem I have is that the code for printing is entirely separate to the code for drawing. I want to merge the two so that common code is used. I'd like to work in the same units for both, which means setting either the pixels per inch for the Graphics object for the printing (so I can work in pixels) or doing the equivalent of the opposite so I can work in inches (printed inches, not screen inches).
VB Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) WebBrowser1.Document.GetElementById("Login").SetAttribute("Value",TextBox1.Text) WebBrowser1.Document.GetElementById("pass").SetAttribute("Value",TextBox2.Text) WebBrowser1.Document.GetElementById("login).InvokeMember("click") 'now the problem is that the following statments finishes up before the preceding statment
I have a black form with wihte letters in it. All the letters are each label.Fore xample, label1 is for the letter C, label2 is for A. Now I want for the form loading to make label1 appear, then wait 500 miliseconds, then label2 appear, then keep waiting 500, then appear. etc. that's 15 labels.so I did
I am using the following code to click a button for displaying another form to click on:
Dim hwnd As Integer = FindWindow(vbNullString, "Virtual CDRom Control Panel") Dim x As Integer = FindWindowEx(hwnd, 0, vbNullString, "Driver Control ...") SendMessage(x, BM_CLICK, 0&, 0&) Thread.Sleep(200) hwnd = FindWindow(vbNullString, "Virtual CD-ROM Driver Control") Debug.Print(hwnd)
I know I'm not the only developer experiencing this issue but only within the last month I started receiving Visual Studio 2010 hangs while running running a simple ASPX web project within the IDE. On stopping the execution or closing the web page VS2010 hangs and becomes completely unusable - stating that VS is busy. It never returns and I have to stop the DEVENV process, resulting in a complete shutdown of VS.
Until now (1 1/2 years) I've been developing a Winforms application with no issues, other than VS2010 IDE errors that have been documented and I've been able to work around. Now, like my Web project, I am also experiencing the same hang but not as frequently. Other documented cases is this forum don't apply in this case since I'm not working with an IIS web site.
Additionally, in reading the forum messages I notice this issue has been around for years and has caused a great deal of grief and delay to many development projects. I'm running Win7 Pro, VS2010 pro on a Pentium Dual-Core CPU 2.20 Ghz with 4 GB memory laptop running in 32 bit mode. I'm very concerned at this stage of the process to upgrade to VS2010 SP1 since I've read too many horror stories online and can't take the risk of affecting the only support environment i have for Winforms application that is currently in production
I have things set up so that the program is ready to start logging ,only when Recieving=true.This is controlled with Button1. So I click button1,Serial port is open and waiting for some signals from the Dyno.When 1 signal come it put a "1" in TextBox1 ,and for the second a "2" and so on. Thing is sometimes it starts right away, like I want it to,and sometimes it lags a fraction of a second, even though the Port is open.When it lags there are already 5 to 10 signals gone by before it starts logging 1,2,3,...and so on. Sometimes it don't start at all.Then I have to close and re-open the form and it works,but with lagging on the first "set"
"Textbox1 > 0 then" triggers a timer (not seen in this code)that samples Textbox1 once pre interval and writes the value to a listbox. On the upside as soon as a "1" is displayed in textbox1 the timer starts like it's supposed to.I noticed this behaviour before I added the timer and besides the timer has nothing to do with the signals coming from the SerialPort. I have my form setup so I can run "sets".Run one "set"...save...reset...run another "set" ...and compare.It's always the first "set" thats off.If I run multiple "sets" the first one is completely "whacked", and the rest are consistent.
Think this could be the SerialPort lagging,or code problems?
Public Class Form1
Dim resetValues As Boolean = False Dim RPM As Double
I have a little log in screen that pops up if a user selects a certain item on my main form. How do I get my code to stop executing til my log in form closes?This is what I am doing so far. Basically i want o execute the code after MyLogin closes.
BMSSplash.MyLogin.Show() If isLoggedIn Then BMSSplash.MyBuddy.Show() Cursor.Current = Cursors.WaitCursor End If
I have coded a low-level mouse hook. Each time the user clicks (let's say) the left mouse button, a custom event gets fired which is then handled by a form in my application. On the form is a ListView control with the following columns: Time - Application - Button.
I want that ListView to contain the last 1000 mouseclicks made, so each time the CustomMouseClickEvent gets fired, I check for the itemcount of the ListView, I add an item to the ListView and I resize all three columns. Problem is however that this extremely delays the processing of the mouseclick messages.
I'm wondering if it's possible to raise the CustomMouseClickEvent and then handle it in my application while at the same time the mouseclick message is passed on to the next hook to get processed by the systen?
I've been having a problem lately where if I call a sub with a msgbox.styleyesno, it won't go back to the original sub that called it. This is my code:
continuing my project my AV can detect viruses by its filenames.. or fileextensions.. and its a incorrect form of detecting a virus..how will my program detect viruses by its behavior?.. least the common viruses like worms and trojans..
when you start a new projekt, vs2010 makes a new folder for the projekt. when i reach a certain point in my projekt i want to save that version of the projekt.
what i do is make a new folder and copy that projekt to it. projektfolder2 . when i start the projekt in the new folder the sln doesnt work anymore. the vbproj works then. and vs 2010 makes a new sln file one directory down of the old one between the other projekt files.
