Measure Character Werdna10-Mar-04 8:22 Werdna 10-Mar-04 8:22  Is there a way to measure single character? Graphics.MeasureString seems to be off. For example if I have character "i", and the particular font I'm using it's one pixel wide, I'd like to know that it's 1 pixel wide. MeasureString adds some extra space. Re: Measure Character Judah Gabriel Himango10-Mar-04 11:22 Judah Gabriel Himango 10-Mar-04 11:22  Look at the System.Drawing.Graphics.MeasureCharacterRanges method, it should be all you need. Be forewarned: that method won't measure more than 32 characters. Call it recursively if you need to measure more than 32 characters. --------------------------- He who knows that enough is enough will always have enough. -Lao Tsu Re: Measure Character Werdna10-Mar-04 11:51 Werdna 10-Mar-04 11:51  MeasureCharacterRanges makes things even worse. What i'm doing is drawing text on a curve, so I need to draw each character seperately, because each character is at different x, y position and different rotation angle. The way measurestring (or measurecharacterranges) work is that it looks like it's done using fixed width font. Re: Measure Character Heath Stewart10-Mar-04 11:27 Heath Stewart 10-Mar-04 11:27  You should also make sure that the StringFormat you're using has the StringFormatFlags.MeasureTrailingSpaces excluded.   Microsoft MVP, Visual C# My Articles AmbientUserMode Andy H10-Mar-04 8:13 Andy H 10-Mar-04 8:13  I am converting a C++ control to a .NET control. In the C++ control in the OnDraw() method I tested for AmbientUserMode, and painted the background with a hashed brush if !AmbientUserMode, or if AmbientUserMode used the BackColor property. How can I test for AmbientUserMode in C# controls? Re: AmbientUserMode Heath Stewart10-Mar-04 10:05 Heath Stewart 10-Mar-04 10:05  Use the protected DesignMode (boolean) property in your control to determine if the control is currently being designed.   Microsoft MVP, Visual C# My Articles Re: AmbientUserMode Heath Stewart10-Mar-04 11:53 Heath Stewart 10-Mar-04 11:53  One other way if you want to separate your design code from the runtime code (common in the .NET FCL with the .Design assemblies), attribute your class with a Type string for a ControlDesigner[^] in a different assembly so that your Type string would look like "MyNamespace.Design.MyControlDesigner, MyAssembly.Design" (".Design" isn't necessary - just a common naming convention). The ControlDesigner lets you paint over your control (see ControlDesigner.OnPaintAdornments. The designer classes and interfaces can be very powerful when used effectively, and most designer support is built right into the .NET FCL (some is provided by the development environment like VS.NET or SharpDevelop). For more information about extending components with design-time capabilities, see Enhancing Design-Time Support[^] on MSDN.   Microsoft MVP, Visual C# My Articles FileAttributes Jonathan Slenders10-Mar-04 7:36 Jonathan Slenders 10-Mar-04 7:36  How can i change the fileattributes of a file (or folder). I will change the Read-only, Hidden, archive,... tags but i can't find it somewhere. It was no problem to change the creation, last access and last written time, but that class (FileInfo and DirectoryInfo) doesn't have anything to change the attributes of it. Can you help me? Jonathan Slenders Re: FileAttributes Mike Ellison10-Mar-04 8:14 Mike Ellison 10-Mar-04 8:14  Hi Jonathan. Try the System.IO.File.SetAttributes()[^] static method. Re: FileAttributes Heath Stewart10-Mar-04 10:14 Heath Stewart 10-Mar-04 10:14  See FileInfo.Attributes (inherited form FileSystemInfo). You can use bitwise operators to change the flags. For instance, to exclude the read-only, hidden, and archive flags, you could do something like this: FileInfo info = new FileInfo("path"); info.Attributes &= ~(FileAttributes.ReadOnly | FileAttributes.Hidden | FileAttributes.Archive);   Microsoft MVP, Visual C# My Articles Just like the System Clock Guinness4Strength10-Mar-04 6:23 Guinness4Strength 10-Mar-04 6:23  I want to replace the System Clock ("Date & Time properties") in the sys tray with my own.

Re: Just like the System Clock Heath Stewart10-Mar-04 6:26 Heath Stewart 10-Mar-04 6:26  Unless you can fit readable text into a 16x16 pixel icon, you can't. The system clock is not a systray icon and is handled specially by Windows.   Microsoft MVP, Visual C# My Articles hello! help for SMSC class ftanriov10-Mar-04 5:59 ftanriov 10-Mar-04 5:59  I've gor the code to send SMS, but it gives an error message!

Since this is not a .NET class provided by the Framework class library (FCL), it's difficult to know what you're doing wrong since this is a third-party control. You should always provide error information when asking for help on an error anyway.   Microsoft MVP, Visual C# My Articles Re: hello! help for SMSC class ftanriov10-Mar-04 6:48 ftanriov 10-Mar-04 6:48  Hi, thank you for your advices Error is: Server Error in '/my_p' Application. -------------------------------------------------------------------------------- The specified module could not be found.

You should put this either in the bin sub-directory of your web application or install it into the GAC by dragging into %windir%\assembly or using gacutil -i theAssembly.dll (only referencing the SMS assembly). Anything beyond that, you should consult the web site for the SMS assembly you're using.   Microsoft MVP, Visual C# My Articles Re: hello! help for SMSC class ftanriov10-Mar-04 6:52 ftanriov 10-Mar-04 6:52  Aaand please check this link to understand what I'm dealing with... best regards jenny Re: hello! help for SMSC class ftanriov10-Mar-04 6:57 ftanriov 10-Mar-04 6:57  https://www.exhedra.com/vb/scripts/ShowCode.asp?txtCodeId=1404&lngWId=10 ups sorry! well, i am sleeping i forgot to write the url jenny Interop with MSDev from a C# application Eric Marchesin10-Mar-04 4:10 Eric Marchesin 10-Mar-04 4:10  Hello ! I'm writing an application in C# that must be able to look for information in MSDev if at least one MSDev process is running. Precisely, I'd like to get the list of the files that are currently opened in the MS-Dev editor. I think I must add a Reference such as : COM / Visual C++ Text Editor But I don't know how to use the component... Does anybody know the right way to do that ? Best regards, - Éric - Re: Interop with MSDev from a C# application Mazdak10-Mar-04 5:03 Mazdak 10-Mar-04 5:03  Write click on Referenes in your project, select Add Reference then from COM tab browse your dll then simply you can add namespace and use it.

You can find more information about this on MSDN, Manipulating the Development Environment[^]. More easily, just create a new add-in project in VS.NET. You can get access to the open files (the text editor itself won't help) from there. If you're trying to do this external the development environment, I'm not sure how you could get a reference to the EnvDTE object or if it's even possible. I do know that devenv.exe does register open files in the running object table (ROT). You could P/Invoke GetrunningObjectTable to get a reference to the IRunningObjetTable (a COM interface, so you'll have to import it or re-define it in C#). You can then enumerate the objects using the EnumRunning method with an IEnumMoniker (forunately, .NET already exposes the UCOMIEnumMoniker interface so you don't have to define IEnumMoniker). From there, you can get file monikers, filtering on devenv.exe to get the open documents. COM programming experience will be helpful.   Microsoft MVP, Visual C# My Articles Re: Interop with MSDev from a C# application Eric Marchesin10-Mar-04 7:33 Eric Marchesin 10-Mar-04 7:33  Actually I'm trying to do this from a standalone C# application other than Visual Studio (so it's not an add-in). I'd like to connect with the MSDev.exe process (if one exists) through a COM interface I guess. I've heard about ITextDocument, ActiveDocument, etc... but I don't know how to reach these interfaces or even if they're the ones I must try to get. I wish I could find an example of 'communication' between MSDev and a .NET application because I don't know much about COM Anyway thank you, - Éric - Re: Interop with MSDev from a C# application Heath Stewart10-Mar-04 9:57 Heath Stewart 10-Mar-04 9:57  In order to get those properties, you must have a reference to the DTE object that the environment exposes. All those interfaces are contained in the EnvDTE assembly. While you won't be making a plugin, you'll still need that to get the objects and their properties within the environment. There is no way to get a reference to the DTE object with the information provided by the Process class. You could, possibly, use Marshal.GetActiveObject("VsmIDE.DTE") to get an instance of the msdev.exe DTE object (msdev.exe is for Visual Studio 6, where devenv.exe is for VS.NET 7.0 and 7.1 currently), casting that to a DTE variable (if the process is alive, in which case it adds a moniker to the ROT). This may work, but it's untested.   Microsoft MVP, Visual C# My Articles Re: Interop with MSDev from a C# application Eric Marchesin10-Mar-04 21:40 Eric Marchesin 10-Mar-04 21:40  It seems to be that... using System.Runtime.InteropServices; But I'm quite lost since I'm not pretty familiar with COM functionnalities. So I want to get the DTE for Visual Studio 6 and when I write : object O = Marshal.GetActiveObject("VsmIDE.DTE"); ... I get a COMException saying "Invalid class string". If you had any idea to help me to solve this issue, I'd be really glad ! - Éric -
