• Visual C++ CFile Data Removal probs

  Is There any short way to remove some lines from a file say there is a file called Hello.dat contains 5000 lines 1) In that i just want read first 200 lines 2) Preform some operation 3) remove them i.e. 200 lines if the operation is successful //This is the problem i.e. the third task Some efficient was i.e. without creating another file i.e. new file Sarguna Unfortunately, it seems the Operating System does not allow shortening of a file by removing data at the beginning. It only allows truncation of the tail. Therefore I think it is not possible to solve your problem without read and write operations (on the same or two files). But I would consider the following approach. The first value of your file should be reserved: i ...Show All

• .NET Development Derived classes - how to find derived class' attributes from base class

  Hi everyone, I come from a PHP background and I'm starting a new project in C#.net 2005 (express). My question regards base classes and getting a list of attributes of the instantiated derived class from within the original base class - i.e: Have base class declare a function that will set all the attributes of the instantiated class from a provided hashtable. Pseudo-code: --------------------------------- class base() { protected populate_from_array(Hashtable in_vals) { foreach(object[] entry in in_vals) { if (entry[0] is one of the calling classes attributes) attribute = entry[1] } } } class whatever : base { public string name; } //main programming loop: Hashtable w_vals = new Hashtable(); w_vals.Add(" ...Show All

• Visual Basic Automatic Namespace generation in VB

  I've just finished a dll written in VB. I've never bothered with namespaces much until now, but this is a bit complex, so I've arranged it into sub-folders, with a top-level class, a few sub-classes (and base classes), and other classes that hang off some of the sub-classes. Every class has the same "Namespace Handler" around it. Looks garbage in the object viewer - every class is under the root namespace. When using the object however, it looks fine, i.e. you only see the correct sub-sub-classes hanging off the correct sub-classes, etc. However, one of my colleagues who talks C# had a look at my code, and commented that my namespaces were not declared properly, then we discovered that when coding in C#, the namespace line wer ...Show All

• Software Development for Windows Vista FindFirstUrlCacheEntry and COOKIE_CACHE_ENTRY

  Hi, I'm trying to enumerate the cookies on a user's machine and present them to the user along with the associated cookie information. Using the FindFirstURLCacheEntry(Ex) and FindNextURLCacheEntry(Ex) API functions I can do this successfully in Win XP (and in Win XP with IE7 installed so it does not appear to be an IE7 issue). After having looked at the msdn entry for these functions they are listed as supported in Vista but, despite having cookies on my machine and confirming as much by looking in the cookies directory, these functions are not listing out the cookies. Is there a new API to retrieve them or is Vista storing the information differently or are they just flagged differently and it hasn't been documented Any he ...Show All

• Windows Forms Problem displaying image with alpha

  Hi, I'm having some problems displaying an image with alpha. Here's what I have // get the image bits from an handle IntPtr imgBits = GetSurfaceBits(m_surfaceId); // create a new bitmap from these bits m_bmp = new Bitmap(512, 512, 4 * 512, PixelFormat.Format32bppPArgb, imgBits); To display it: private void panel1_Paint(object sender, PaintEventArgs e) { using (Graphics g = e.Graphics) { // clears the panel to blue g.Clear(Color.CornflowerBlue); // this doesn't do anything if (m_bmp != null) g.DrawImage(m_bmp, 0, 0, m_bmp.Width, m_bmp.Height); } } I'll just get a blue panel when doing this. The bitmap is correct because if I do: m_bmp.Save("test.png", ImageFormat.Png); the image gets saved correctly ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XACT audio sounds cutting out

  Hi all, I have a static class I'm using to play sounds loaded in the content pipeline through an xact audio project. In my game, several of the same sound can be played within a few milliseconds of each other. They're basically explosion sounds. Now when I hit more than three of these objects and they play their sound within a short space of time, the sounds cut each other out and sometimes don't play at all which is very poor. I'm not limiting instances in the audio project although I've tried every permutation of this I can think of anyway. I know about the garbage collection issue when using cue objects that aren't referenced etc. but I'm actually just using soundbank.playsound and not getting the cue object at all. ...Show All
