• Windows Forms Temporarily disable an event handler at runtime

  In C# (Visual Studio), can I temporarily disable an event handler at runtime Details please. The classic reason you'd ask something like this is that you're doing something in code that triggers an event handler that you'd normally like to only run when the user does something. Add a form/class member of type bool that you set to true when you make run your code, it will be false when the user does something... ...Show All

• Visual Basic Printing data with Type1 Fonts in VB.Net

  Hi, We are developing Windows application in VB.Net (VS 2005). Our requirement is to print data to the default printer. We are using PrintDocument() to achieve this. As per requirement we have to print in specific fonts, the fonts are of type "Type1". When we used following code. e.graphics.DrawString("My Company Name", New Font("HelvCondBlk", objFont.PassHeaderFontSize, FontStyle.Bold), Brushes.White, rectWB) The application could not recognize the Type1 font. These fonts are also not listed in FontFamily.Families. Please let me know how to print any document from VB.Net in Type1 font.

• .NET Development <?xml version='1.1' . . .

  ...and .NET Framework > Well, I'll BEA monkey's uncle. It's a deceptively short grammatically incorrect question with an exceedingly short answer. Try it in IE7/FIrefox/VS2005, the answer is apparently "no." Nothing in MSXML 6.0 about XML Schema 1.1 Opinions, gripes, thoughts, theories, and even, "w.t.f. " appreciated. I've read the rationale here . Check. Fresh ink. I understand the burning desire...to break competitor's code. Check.

• Visual Studio 2008 (Pre-release) Callback and IsOneWay=false

  Hello, I am working on a service that need to callback to clients, not for notifications only, service need to get data from client with that callback, exactly a Bitmap Object. So, the callback method has IsOneWay attribute to false. It works quite irregular. Normally, the service get the Bitmap for the first call, and then service and client become crazy, sometimes work, and somtimes not. Debuging, my code is ok, by the output pane of VS shows this two times: "A first chance exception of type 'System.ServiceModel.ProtocolException' occurred in mscorlib.dll". Any idea what is happening is a June CTP issue callback methods can not be two-way Thanks for any help. regards David Hi again, tracing, I ...Show All

• Visual Studio 2008 (Pre-release) Arrange with no ArrangeOverride call

  Hello there, I have a panel with some children on it. I use a custom logic to arrange its children, which is accomplished by Measure & Arrange overrides. That works fine. Under certain circumstances children of my panel get rearranged with NO(!) ArrangeOverride call (if it would be called, it simply won't let to re-arrange children the way it happens). Those circumstances include but not limited to the following cases: adorner was added for the parent of my custom table, another element was added as a child for the parent of my custom panel. I'm wondering WHEN and WHAT can cause repositioning of child elements bypassing ArrangeOverride Here’s my understanding - when arranging, using Arrange(Rect) no changes to Margin happ ...Show All

• Windows Forms DataGridView Datasource property

  ArrayList Ips=c1.getIPs(); dataGridView1.DataSource = Ips; The getIps returns an arraylist with count 1 the content of arraylist 0th element is 'Pencil'. but in grid its displaying the length of string i.e 6 rather than displaying Pencil.What should i do to display the content of arraylist rather than the length. regards Your arraylist is probably filled with simple strings. You need to fill it with some custom objects, which would expose appropriate properties, e.g.: public class IP { private string text; public IP() {} public IP(string text) { this.text = text; } public string Text { get { return text; } set { text = value; } } } ...

• Game Technologies: DirectX, XNA, XACT, etc. avoid tearing

  Just running throught the basic "How To"s in the help pages and adding sprites. I'm getting tearing as it's rendering. Anyone find how to get a swap chain working so I don't get as much tearing Heh, i'm guessing this question gets ignored because no one really has a good answer :) Thanks guys for trying. I'm going to ask again in the specific context of Spacewars. With Spacewars i get absolutely terrible performance in windowed mode. The game is not even playable the framerate is so low.

• Smart Device Development short alignment issue

  I'm seeing something very weird when compiling this code for an ARMV4i Smartphone target and running it on a smartphone emulator: INT foo(UINT16 *srcPtr) { short data; data = *(srcPtr+1); switch (*srcPtr) {... } If the memory pointed to by srcPtr contains: 11 22 33 44 55 66 77 88 data is set to 0x88776655 (endianism isn't the issue, but 32 instead of 16 bits is - it should be 0x4433) *srcPtr is evaluated as 0x44332211, again 32 instead of 16 bits, it should be 0x2211. Any ideas Cheers, Ken It wouldn't surprise me if intellisense gave you a different definition than the one really being used by the compiler.

• SQL Server How to get mobile subscription to sync with dynamic snapshot

  Hello Everyone, I have a publication on a Sql 2000 (SP4) server. This publication has dynamic filtering enabled. What I want to do is create an interface which will generate a new dynamic snapshot based on filtering input from users. So far I can create the dynamic snapshot easy enough and I can see the filtered results on a Sql 2000 subscriber. However, there seems to be no way to configure a mobile database to point to the dynamic snapshot. This is easy to configure in a Sql 2000 subscription - the options are right there are on the properties page. Yet, it seems like the mobile database only points to the required unfiltered snapshot through the IIS proxy. Is there any way to force the mobile database to use the dynamic snapshot ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Buttermilk Game Engine and LGPL

  I'd like for Buttermilk to have the following features in its license - Free to use and redistribute. Free to publish commercial games on Windows. Free to publish free or commercial games on the XBox360 (XBLA, etc). Basically no restrictions except don't pass my code off as something you made :) Will LGPL do this I hear it's looser than GPL. The looser the better, methinks. Check out the BSD license. The MPL is a pretty good one for that, as well. There's another license that basically says you can do whatever you want with, so long as you don't use it to duplicate the original functionality commercially - I'm not explaining that well. Basically, on a physics library, you couldn't use it as the basis of a commercial ph ...Show All
