I'm tired of having my dropdownmenu come up in my printpreview and print, so I've decided to use a timer and a progress bar to wait a few seconds before the print or printpreview is started.[code]The problem I have is when I go to print or printpreview, it will work but the program stops debugging and tells me that the form has to be focused. What up with dat?

I'm have a program filled with forms for the user to enter data to determine fluid and reservoir properties. I want the ability to be able to print out the forms so they may be kept in binders. I'm using the PrintForm function from the Visual Basic PowerPacks but I'm having a problem getting some of the larger forms onto a single page. Is there anyway to zoom or autofit using this function? I've already tried adjusting the margins and that is not enough. I've been trying to look through the object browser but it hasn't worked very well yet.
View 10 RepliesI have a form which i need to print, however, I need to know how to format it, margins, etc... I've got it to work by adding the PrintForm powerpack and using the simple code below, but the margins are too big and it is not printing the rich text box I have.[code]....
View 9 RepliesI have created a windows application and it was working fine, then I added in the printform component from PowerPack3 and here the error starts. The application works fine on the computer I wrote it on, but when I move the exe over to another computer (which I have installed PP3 and the .net framework) I get an error. The only difference between the computer I am writing it on and trying to run it on, is that this computer has vb.net 2010 express edition installed. What do I need to do from here to get this working?

View 11 RepliesI have a form that I am using "PrintForm" to print out, however there is a notes section that can contain a lot of text, seeing as the Printform function only takes a bitmap of the form, it cuts off the text.

First is the code for printing the bitmap - second the textbox

I am creating a program that I would like to distribute. I am using printform in VB 2008 to print my form. My form is the size of my computer screen...15 in. If the program is run on a different computer with a different screen size, will it affect the appearance of the form on the screen or the printing of the form? If the form is run on a laptop, for example, with a smaller screen, will it cut off my form and thus cut off the form during printing? Will a bigger screen increase the size of the form and not allow it to fit correctly when printed? I was just curious and wondering.
View 6 RepliesI am printing my form by using the printdocument of VS and the printform found in powerpacks. I never got the preview to work so when ever I want to print I send my information on a new form (form1) which I have altered ( colour borders ) so it is printable. To print form1 I have added a toolstrip with a print button so when the user sees all is ok on the form1 he clicks on it which hides the toolstrip and prints form1. All this sequence works fine. The problem I have been getting lately is that I can print on the first try but when I call another form to print the toolstrip ( with the print button ) is always hidden. I have to exit the application and re enter to get it to show up. Any solution to this or even how to print in a better way. (have the preview to work for example ). I have tried to use printdialog to print but I have never been able to send the document to print.
View 4 RepliesI'm trying to use PrintToFile from the Power Packs PrintForm Class and I have a question. I'm able to save the form to a file, but now how to print it later if needed. MSDN says that it's saved as an Encapsulated PostScript file. Adobe Illustrator claims it will open EPS file, but it won't open this one. How I can print this file in vb.net? If you've never used this before, here is my sample code to save the form to file in case someone wants to test it out.
If SaveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
Me.PrintForm1.PrintFileName = SaveFileDialog1.FileName & ".eps"Me.PrintForm1.PrintAction = Printing.PrintAction.PrintToFile
Me.PrintForm1.Print(Me,PowerPacks.Printing.PrintForm.PrintOption.Scrollable)
End If
I have been working at printing receipts using printform, but the printer does not seem to be receiving any information from the form. Here is the
Public Sub PrintReceipt()

When I use the "PrintToPreview" print action, there is nothing shown on the screen.
I have created a form that we use for our employee goal setting. I would like to let the users print the form. The form is quite large and has scroll bars. I am trying to use the Printform to print the form. I would like to use autofit or some other type of scaling to get the form to fit on one page. I have done some looking aroung and have seen the following instrutions a couple of times.
1.Drag a PrintForm component onto the Form from the Visual Studio Toolbox
2.Set the PrintForm.BodyContainer property to reference your Form
3.Drag a PrintPreviewDialog component onto your Form from the Visual Studio Toolbox
4.Set the PrintPreviewDialog.Document property to reference the PrintForm component
5.Add a button and button click handler. In the handler call PrintPreviewDialog.ShowDialog()
I don't know how to set the PrintForm.BodyContainer propery (number 2). I am using Visual Basic 2010 express.
I'm using PrintForm which comes with PowerPack to print a form with a couple of Labels into it.But the letters appear a little blur and not clear at all, bad quality, I tried by increasing the size of the labels but the result was the same.Under the PrintForm parameters I only found one that could be relevant, the papersize but that doesn't helped too.

View 6 RepliesI need an accurate timer to interface a Windows application to a piece of lab equipment.I used System.Timers.Timer() to create a timer that ticks every 10 msec, but this clock runs slow. For example 1000 ticks with an interval of 10 msec should take 10 wall-clock seconds, but it actually takes more like 20 wall-clock sec (on my PC). I am guessing this is because System.Timers.Timer() is an interval timer that is reset every time it elapses. Since it will always take some time between when the timer elapses and when it is reset (to another 10msec) the clock will run slow. This probably fine if the interval is large (seconds or minutes) but unacceptable for very short intervals.Is there a function on Windows that will trigger a procedure every time the system clock crosses a 10 msec (or whatever) boundary?
UPDATE: System.Timers.Timer() is extremely inaccurate for small intervals.I wrote a simple program that counted 10 seconds several ways:
Interval=1, Count=10000, Run time = 160 sec, msec per interval=16
Interval=10, Count=1000, Run time = 16 sec, msec per interval=15
Interval=100, Count=100, Run time = 11 sec, msec per interval=110
Interval=1000, Count=10, Run time = 10 sec, msec per interval=1000
It seems like System.Timers.Timer() cannot tick faster that about 15 msec, regardless of the interval setting.Note that none of these tests seemed to use any measurable CPU time, so the limit is not the CPU, just a .net limitation (bug?)For now I think I can live with an inaccurate timer that triggers a routine every 15 msec or so and the routine gets an accurate system time. Kinda strange, but...I also found a shareware product ZylTimer.NET that claims to be a much more accurate .net timer (resolution of 1-2 msec). This may be what I need. If there is one product there are likely others.
I have a timer on a page in ASP.NET.
After a certain period of time elapses, I want to disable the timer.
I want to put a static variable in the timers tick event that will track how many seconds have elapsed.
My question is, will this work?
If user X and Y are viewing the page will they both have separate local static variables?
What is the best method of shutting down an ASP.NET timer after a certain elapsed time?
I have a windows application that need to process som quite time consuming jobs. In my first try i did all processing under
the form thread. The result was bad response and update of the form due to the heavy jobs.To get around the problem with bad response from the form i created a new class "processing" where i put all the data processing. Then i instanciated a background worker where i in the "doWork" sub created a new instance of "processing".The "processing" class creates a timer from system.timer, and the timer drives the processing.On the Timer event Elapsed the timer starts a new thread from the thread pool.
My problem is now when i want to asynchronously close the background worker (with the corresponding function call what ever it is called ...) there is still a timer thread out there that causes exceptions for me.
1. How can i close my background worker and at the same time have the timer to be stopped?
2. Is there a way to synchronize the timer event so that the timer executes from the background worker thread?
3. Is there a better approach for me to adapt?
I want to create an array of timer in vb.net. My problem is that how will i raise the tick event for a particular timer, say mytimer(x).tick and inside the tick event there is also a button, say mybutton(x) which changes location every interval. for example:
public class blah
dim mybuttons(20) as button
dim mytimer(20) as timer
private sub form_load(....) handles me.load
for x as integer = 0 to 20
[Code]...
i dont know what to do next, all i want is to pass the button mybuttons(x) to mytimer(x) tick event, in which their index number are the same. i want to create one timer per button. how to do that? please help me and post example codes. i've researched the net but i cant understand passing variables, addhandlers, etc. i'm just new to programming object oriented.
How can I incorporate the timer so once a page loads the timer activates, waits a few seconds then I tell my program what to do next.I tried this code but it didnt work:
Timer1.Interval = 5000
Timer1.Enabled = True

I wrote an application to handle a joystick with directinput. It works fine if it uses the handle of the main window but it doesnt happen the same if the handle is the one of the component that contains the joystick's operation.
I mean:
main form handle: 15
component handle (which is inside the window and the joystick needs the focus of this component to work): 25
It always work if the handle i initilizate the device is the main form (15).How can i use only the handle of the component?

By the way is not a problem of mouse_event, is the timer that doesn't work
I have a timer in vb.net and it's interval is 1000ms ,. i have placed in it's timer_tick event a code that will print screen the screen and save it to a database.The problem is when i click outside of the form, or loosing the focus of the mouse to the form containing that timer/printscreen, the timer stops. As a result the printscreen also stops.here are it's properties:
generate member = true
interval = 1000
modifiers = friend
I recently switched my code from using the windows.forms.timer to the systems.timer.timer and it has resulted in a multithreading error. I'm using the timer to trigger just one event so multithreading shouldn't be an issue. To give more detail I have implemented the timer at follows:
At the top of the class I have: Private Shared timr1sec As System.Timers.Timer
When the program loads (Private Sub Test_load):
timr1sec = New System.Timers.Timer(1000)
AddHandler timr1sec.Elapsed, AddressOf OnTimedEvent
In OnTimedEvent I call several subroutines, and write some data to the screen using a ListView object.VisualExpress throws the multithreading error on the last line of this code, which is in OnTimedEvent

I have a routine which is controlled by a timer. It works perfectly. The problem is that now, I need to run this routine several times, so I need to start differents threads so that my program doesn't get hung up. I've been trying to start my timer inside a thread, but it doesn't work!
