• Visual C++ First Execution Only...

  Hi, I've been trying to tell my new program to check for a specific condition (whether it is the first execution or not), but I'm having quite a bit of trouble. In fact, it's driving me insane. I spent almost all of last night trying to get this right, but it simply will not work the way I want it to. I've asked a huge number of people for help on message boards across the net, and nobody has been willing to help me fix it. So this is my last chance. PLEASE help me. Anyways, here's what I have so far, see if you can fix it and point out what I'm doing wrong: Prototype : int Config (int firstrun); Cut from main() : int firstrun; Config(firstrun); int temp1 = 1; int temp2 = 0; if (firstrun == temp1) { cou ...Show All

• Windows Forms Different size on ToolstripMenuItems

  Is it possible to mix toolstripmenuitems of different heights in a toolstripmenu Now, if I have a menuitem with text on 3 rows, the other items with only one row will try to align the text relative to the center of the 3-row-height. I've tried everything but nothing works. Look at this picture: http://erik.er.funpic.org/temp/strangetoolstrip.png Here i have an item with a picture that resizes the height of the item to about 100px. The second item will get 100px height automaticly and also centers the text verticaly ( even if i've changed text-align to top-left! is this a bug or does text-alignment do something else ). On the third item i've manually changed autosize to false and height to 20px. But there is no text there, i ...Show All

• .NET Development Cross Thread Problem with SerialPort DataReceived Event

  I am writing a custom Ref Class with C++ 2005 to control a measurement instrument via Serial Port. My class inherets System::IO::Ports::SerialPort. I also define events inside my class to generate action on specific RS232 messaages. My problem is as follows: Inside the datareceived event handler, I raise events based on messages reveived. However, when my class is instantiated on a windows form, if the event handler defined on the form changes properties of a textbox control, the sytem generates "System.InvalidOperation Exception" and goes on to describe that a different thread tried to access the control. I can solve the problem by setting the CheckForIllegalCrossThreadCalls property of the Windows Form to false. ...Show All

• Visual Studio 2008 (Pre-release) Is it possible to show video from MemoryStream not from Uri?

  We need to show video from memory stream, but MediaElement support only Uri as Source How can I solve this problem Should I write own control that inherete some base class such as it realized in MediaElement control Or maybe new release of WPF will support different types of source for MediaElement You're right, currently there is no native way to show video from a memory stream. If you have a standalone WPF app (not an XBAP), you may be able to workaround by saving the stream to a temporary file and referencing that. In future, we'd like to make this scenario possible. I haven't done this myself but you could explore custom protocol handler support in the Windows Media foundation. Perhaps there' ...Show All

• SQL Server Non windows clients

  What about non windows clients (mac, linux etc) Can they access Reporting Services with personal permissions/settings as long as they are given a windows account on the RS-machine/domain Or... do I have to implement custom security in order to give access to non-windows users Regards Andreas At its simplest, the clients can be given access the Report Manager. You can configure the Report Manager for basic authentication and browser would prompt the user for credentials. Once the user enters the credentials of the local Windows account, she will be given access to the Report Server based on the permissions this account has to the report catalog. ...Show All

• Visual Studio 2008 (Pre-release) Selector.IsSelected in RC1

  I have an ItemContainerStyle on a ListView witch has a trigger on Selector.IsSelected, but it seems to have no effect in RC1 Best regards, Thomas Andersen I agree, I would like to change the template as the last resort. there are many places where changing a simple property is not possible because of the way the controls are templated. I thought something like this would work, but it is not. this approach was working before, If I remember correctly < Style x:Key = " st1 " TargetType = " {x:Type ListViewItem} " > < Style.Resources > < SolidColorBrush x:Key = " {x:Static SystemColors.ControlBrushKey} " > #FFFF0000 </ SolidColorBrus ...Show All

  hey. i want to code a program that includes a metronome using c++ and directSound and/or directMusic. this metronome should raise an event periodically, it should be as precise as possible and i need to change the tempo at runtime. now what i need is something like the StartTimer (UINT TimerDuration) onTimer(UINT nIDEvent) killTimer() functions in VC++ but with a higher resolution than milli-seconds and with a way to affect the duration between the timer events at runtime, as mentioned above, thus without having to stop and restart the timer... is there a way to use directSound / directMusic in order to achieve this perhaps sth with IReferenceClock:: AdvisePeriodic or does this problem not really have anything to do with ...Show All
