    - Why To Not Use Threading.Sleep in Your Application First of all, I hope that everyone who is interested joins in this conversation especially SJ, Carsten, Spotty, Andreas and Nobugz. Experienced developers here often see new developers experiencing difficulty after calling Threading.Sleep and more experienced developers take issue with its use but rarely is there ever a comprehensive explanation for that. I thought I’d start a thread on this with background as to why we say these things. First of all some background information is needed. In Windows operating systems, when one runs a process, they are starting a process. A process is a contextual environment for a program and it will allow a program to call the things it needs to run. These aspects of a process are kept fairly transparent to a developer but a process has properties external and internal to it. Externally, a process needs to send and receive messages so that controls (including forms) can behave as expected. Internally, transparent to basic developers there are message pumps for dispatching these messages to a users code and controls. A basic property that is expected of a process is that it be able to send and receive these messages which enable Windows to work. Threading.Sleep disables that ability. Often we see upset users who have strange problems who have just called Sleep. “Sleep” disables a process ability to respond to anything internally or externally for the duration of Sleep call. Fundamentally then, a basic principle of a windows environment is that it is event driven and sleep disables the ability to process any and all events. Symptoms will be controls not working and forms not updating. Often the new developer wants to wait on something and they call sleep and because the basic properties of a process have been altered, the new user see unexpected results. Here is a design often seen here: Private Sub PD() While Not Condition ‘ User Loop ‘Process Data ‘Process Data Sleep If SomeCondition then Condition = true End while There is a strong desire on the part of the beginner to want to use sleep to manage basic design flaws which disables a programs ability to respond to internal messages and events. Beyond the process put into sleep states inability to respond to low Level GUI messages, the process also cannot respond to timers. In other Operating systems there are states analogous to Sleep which is not as severe. A process can wake up to handle asynchronous execution so you might see designs analogous to this: Subroutine Main() Hibernate End Sub ASynchronousHandler1 End Sub ASynchronousHandler2 End Sub Such a program is immediately put to sleep and when there is the delivery of an asynchronous event, it’s processed and the process goes back to sleep. The event could be a timer expiration or I/O completion etc. This architecture is useful for a program that handles something and then goes back to sleep. In other words, it’s the basic design for a server. There is no analogous state in Dot Net and hence other techniques are used. This discussion would not be meaningful without offering models for the proper way code deal with issues like these: Class Whatever Protected Structure Wood Public Arg1 as integer Public Arg2 as Integer End Structure Private Wood1 as Wood Protected friend withevents tmr as new System.Windows.Forms.Timer Form1_load ( ByVal sender As Object , ByVal e As System.EventArgs) _ Handles Form1.load Tmr.stop tmr.interval = 250 ‘ one quarter of second interval ‘ Your load code End Sub Private Sub ProcessData(ArgA, Argb, ArgC) Wood1 = new wood Wood1.Arg1 = ArgA ‘ pack up data to process (Context) Wood1.Arg2 = ArgB Tmr.Start End Sub Private Sub Tmr_Tick ( ByVal sender As Object , ByVal e As System.EventArgs) _ Handles Tmr.Tic Tmr.stop ‘Unpack the data and process it ‘ From the data determine if we are finished If Finshed then CompletionRoutine(wood1) else Tmr.Start Return End Sub ‘ Private Sub CompletionRoutine(Wood1 as Wood) ‘resume whatever you need to do End Sub End Class This way the process never goes to sleep and remains responsive to users and data. With a little added complexity much is gained. I’ve written over one hundred thousands lines of Dot net and have only used Sleep once. It was in a toolbar which moved itself. The effect I wanted was a gliding effect so I’d move the toolbar a couple of pixels and sleep for a few milliseconds, schieving exactly the effect I wanted. But here is what often turns up in this forum: Private Subroutine Foo() WebBrowser.Nagivate(“www.foo.com”) While Not WebBrowser.DocumentComplete Sleep (50) End While ‘Continue processing End Sub This is REALLY BAD code. What if the URL is not there or it times out This process will never wakeup and sit like the rock of Gibraltar on your desktop until you kill it with Task Manager. Here, the user should have used an event: Private Subroutine Foo() WebBrowser.Nagivate(“www.foo.com”) End Sub Private Sub WebBrowser_NavigationComplete ( ByVal sender As Object , _ ByVal e As System.NavigationEventArgs) _ Handles WbBrowser.NaVigationComplete ‘Process the data and continue End Sub I’ve come to see calling Threading.Sleep is having strayed into a fundamental design error, the possibility that a developer does not understand event handlers or they have missed a control or a component's events.

This is what i have so far in a button click event: Me.MaintableDataGridView.CurrentCell.Selected = False Me.MaintableDataGridView.Rows(0).Cells(0).Selected = True This works great but i just want to move 1 cell up, not by coordinates.

    - form transparent sometimes We are developing a windows application at the moment. I built the program successfully, and then copy them across to one of my colleague's computer for testing. Generally the program works fine, except sometimes my colleague can see through the form (see the background image) when he showed the menu dropdown menu items across the toolstrip and even click on the icons behind! This weird behavior of the program is not visible on my computer. Note I copied all the dll,exe,manifest files from the debug folder to his computer.

    - web browser stuff.. Heya guys. I have a few question regarding to building a C# web browser using the web browser tool in VS C# Express. I was hoping you could answer me. I'm really new so I'd appreciate code examples or not too complex explanations. 1. When I enter my web browser application a splash screen I built pops up. I want it to pop up only the first time I enter the application and then, when I want to open more windows of this same app or so, I'll get it straight away with no splash screen (I created the splash screen for visual effect only, I don't really require it). 2. When I navigate to a site I want to get its title. For example "Google search: bla bla". Just like in all decent web browsers. I found out that when you hit properties on a page it gives you the title of it. How can I access this info and how can I throw it into my form name 3. The problem that annoys me the most is when I hit links that need to open in new windows in my own browser, they open up in IE. I have no idea how to fix this one. I would also like my app to open another window when I right-click a link and hit Open In New Window. How can I do this (I have a feeling I'll have a rough time understanding your suggestions so remember I'm a newbie). If it would help I could send you the solution and you'll get to see the mess I wrote here. That's about it.. I know it's a lot but I'll be grateful for anyone who will help me with those problems. Thanks, tnl. Tag: Visual Basic Express Edition Hide Password Characters? Visual Studio Express Editions

    - Need help sorting this out databases, arrays, for loops, etc I am trying to figure out the best way to do something: I have 2 datasets. One dataset is called Grid and the other is Coords. I want to do a For Each CurrentRecord As Datarow in Coords In this For Loop I want to subtract each CurrentRecord Value from each CurrentRecord value in Grids and out put them to an array So now I should have seperate arrays for each CurrentRecord value. ie example data/database setup Coords Table Record | X1 = 5 Record | X2 = 3 Record | X3 = 5 Record | X4 = 10 Grid Table Record | A = 1 Record | B = 2 Record | C =3 Record | D = 4 The out put after running the For Loop should be to this effect Array 1 X1 = 5-1 = 4 X1 = 5-2 = 3 X1 = 5-3 = 2 X1 = 5-4 = 1 Array 2 X2 = 3-1 = 2 X2 = 3-2 = 1 X2 = 3-3 = 0 X2 = 3-4 = -1 Array 3 X3 = 5-1 = 4 X3 = 5-2 = 3 X3 = 5-3 = 2 X3 = 5-4 =1 Array 4 X4 = 10-1 = 9 X4 = 10-2 = 8 X4 = 10-3 = 7 X4 = 10-4 = 6 Okay now that we have the data in an array I would like to run a IF Then statement (maybe) to find out which number is the lowest in each array Array 1 X1 = 5-4 = 1 Array 2 X2 = 3-4 = -1 Array 3 X3 = 5-4 =1 Array 4 X4 = 10-4 = 6 In this sample data all the arrays point to Grid D (this is only sample data and will not the the typical outcome). I want to either create a new array or dumb this into a new database table/xml file that X1 is D, X2 is D, X3 is D, X4 is D. I'll also do this for Y and Z, but they will be seperate in data. Anyone willing to help me get started with this Thanks Tag: Visual Basic Express Edition Hide Password Characters? Visual Studio Express Editions

    - Of Pictureboxes, Transparency, Movement and Backgrounds Hi there, I am trying to make a picturebox move over another in a program - one, a stationary red arrow, the other a moving green arrow. When the green arrow picture box moves over the red, you can clearly see that the green picturebox is only *pretending* to be transparent; you can see that the green picturebox is filling the empty spaces with the form's colour, and that box moving over the arrow beneath it. Basically, it looks fairly unprofessional. Is there some way to fix this, so that you *only* see the green arrow moving over the red, and not the form's foreground colour with it I hope that made sense; please let me know if I need to clarify.

Save the file in Unicode format to prevent data loss The point is that the offending line is not designed to work with MSVC. I do not think it right to give such a warning. I found this when compiling a cross-platform project. It has code like above for other platforms. Earlier versions of MSVC do not report this error. The suggestion is useless in my case (won't work). What is more, even for MSVC, the suggestion seems problematic.--When I commented the preprocessor lines except the offending one and saved the file in UTF-16, the character literal passed to printf becomes ` '.--Should the build environment affect the code in such a significant way while providing no controlling options (no encoding or charset options have been found) If I do not set the locale to English and reboot, it seems simply not possible to work without make significant changes to the code (like wprintf(L"%c\n", L'￡'); ).

    - Adding Number in VB I need VB to add a series of values which are stored in text boxes. The code which i am using is: txtTotalQ.Text = txtQuantity1.Text + txtQuantity2.Text + txtQuantity3.Text + txtQuantity4.Text + txtQuantity5.Text + txtQuantity6.Text However it doesn't actually add the numbers up, it just combines them together For example instead of 10+10 = 20 I get 10+10 = 1010 I know their is a basic solution to this, i just cant seem to come up with one (the values in the txtQuanitiy's text boxes, are variables that have been declared as integers) Tag: Visual Basic Express Edition Hide Password Characters?

Is there a way to hide the characters the user enters into a text box, in the same way other applications do when entering a password

Just set the PasswordChar to what you want to display, e.g.

TextBox1.PasswordChar = "*"c

will display asterisks instead of the actual characters you enter.
