• Software Development for Windows Vista what does "Minimum operating systems : Windows Vista" mean in MSDN docs?

  Hi, I 'm a novice windows api programmer. I found out that you need vista version of windows platform sdk when function information in msdn says that minimum operation systems should be windows vista. eg) ChangeWindowMessageFilter Function Function Information Minimum DLL Version user32.dll Header Declared in Winuser.h , include Windows.h Import library User32.lib Minimum operating systems Windows Vista Does this mean that the computer that will run my app should be at least Vista even though I compile it using vista version of windows platform sdk What if I do os-version check in my code and call the function only when user computer is vista Thank you in advance. ...Show All

• Visual Studio Express Editions VB Express 2005 crashes very often

  I d/l'ed VB express and install went flawless. But it seemed the more I used it the more often it started crashing. No particular event causes a crash more than another. Seems all random. Its to the point now where its really not useable. So I uninstalled, and borrowed a copy of Visual Studio from a friend. Same thing. Random crashes all over the place. Something odd on visual studio though, after I build a sql database and connect it to my program, and have a dataset, if I try to make a query with the query builder, the dataset will disappear. So, I uninstalled Visual Studio and reinstalled VB express 2005. Seems at first it appears better, but soon after crash crash crash. I'm not at that computer right now so I don't hav ...Show All

• Smart Device Development URGENT: Unknown file 'Microsoft.WindowsMobile.Utilities.dll'

  Hi there, I'm currently writing an application for the Windows Mobile 5.0 platform. I'm using VS2005, C# and CF 2.0. When I deploy my app, there is a missing library on my customers PDA. This library is 'Microsoft.WindowsMobile.Utilities.dll'. I have searched my disks, but can't locate it anywhere! Does anyone know this library and how to get it best regards Reiner Peter, the PDA of my customer IS a WM 5.0 Device! Although it is a few months older and from a different OEM. The most important difference between the two devices is: my Device is a "PocketPC", the customers device is a "Smartphone"! The most important question for me now is: what can I do best regard ...Show All

• Visual Studio 2008 (Pre-release) Qs on .PNG & .TIF encoderparameters (quality/compression)

  Does anyone happen to know, offhand, if there is a way to specify the quality encoder parameter type for .PNG files that actually causes some effect on the degree of compression I have seen 3rd party imaging software that allows settings for this, usually with a compression level from 1-10, which really works and really can produce good reductions in file size, but my impression is that GDI+ doesn't not support this kind of specification for anything but .JPG files...is that the case Also, the documented and often sited way of setting up for saving in .TIFF format works, but choosing the LZW compression type (which is the only one that appears not to result in an unhandled exception being thrown), doesn't accomplish much in terms of ...Show All

• .NET Development Making a delegate for serialport

  Hi, I got a device attached to my serial port which takes a few commands like "get version". But some commands return big strings which the serial port is not passing all through at once. So i want to make a delegate with an event handler which listens if anything has arrived yet and append it to a rich text box. I've tried a few things, but i keep getting all kinds of errors in runtime. So i undo those changes. This is my code: FIELDS: public SerialPort serialPort; public delegate void GetData(string getDataFromBuffer); public event ReadDataInBuffer dataRead; private string buffer. private void SerialPort_DataReceived(object sender, SerialDataReceivedEventArgs e) { this.buffer += this.serialPort.ReadExisting(); } S ...Show All

• Visual Studio Confused. Can someone assist?

  Good karma to all that assist. I'll explain my goal then i'll show how I went about it. Goal: To Print a DataGridView. Simple enough. Let me know if you need to know more. How I did it: I chose not to program Print objects. Too complicated, too messy. Instead, I chose to design a report to 'look like' the DataGridView. There was available a "design a new report" link of the ReportViewer object which I clicked and which brought me to the canvas for the Report. I thought setting its datasource would be as easy as making a DataTable runtime and setting the datasource. Not so. I decided on making a business object which worked well up to designing the Report by click, drag and drop. My report looked great ...Show All

• Internet Explorer Development IE7 and Right Click Menu

  I have an IE explorer bar which makes use of a Right Click menu option. The right click menu option is implemented the usual way by creating a new key under HKCU\Software\Microsoft\Internet Explorer\MenuExt\<menu text> and this menu is pointing to a file in the local file system. This file is basically a VB Script file which parses the highlighted text passed down to it from the browser and uses that text as a query parameter to lauch another URL from the server (using external.menuArguments.navigate(url)). My Explorer Bar captures this navigation, stops it in the main browser and relaunches it using IWebBrowser2.Navigate so that the URL will show up inside my Explorer Bar rather than the main browser window. Eventually this new URL ...Show All

• Windows Forms reusable menus

  Hi I'd like to create a menustrip that I can reuse in different forms and different projects. My idea was to create a controls library and put it in there, but I can't seem to be able to create a control that inherits from MenuStrip. Any ideas Federico You can create a control which inherits from MenuStrip by using Add -> New item... and choosing "Custom Control", then changing the base class from Control to MenuStrip. However, you won't be able to design the menu using the Designer; you'll have to hand-code the instantiation. The easiest way might be to design the menu in a dummy Form and then copy the relevant code from the Form.Designer.cs to your Custom Control. ...Show All

• Visual Studio Express Editions Updating Qbasic code to Visual Basic

  I found a program that runs fine in QBasic on Windows 98 (about 2 years ago), but since updating to XP have been unable to take screenshots of the output to moniter to create images. Is there any simple way to do this, or do I have to update all the code to Visual Basic just to take a "print screen" This seems highly complicated for the very simple action that I wish to do. :-p Many thanks for any help!! Another free program that can do excellent screen captures is the all purpose graphics program 'irfanview'. (I use it for all sorts of stuff. Highly recommended!) http://www.irfanview.com/ ...Show All

• Visual C++ Visual Studio 2003 C++ IDE with SP1 crashes daily druing builds

  I love how fast my solutions and projects load, and how when I hit debug/run the "build check" happens sooo much faster. But...on two different machines the IDE crashes either when we start a build or sometime during the build. We reload the solution and start again and it normally works fine. It can sometimes crash up to 3x in one day. We can go days without seeing it and then it comes back. Before service pack 1 we did not see this behaviour at all. The 2 machines are Windows 2000 SP4 and XP SP2 both with over 2 GB of memory.
