  • How do I read a binary file in C#?

    - by tomcamara
    I have a file that exists within a text and a binary image, I need to read from 0 to 30 position the text in question, and the position on 31 would be the image in binary format. What are the steps that I have to follow to proceed with that problem? Currently, I am trying to read it using FileStream, and then I move the FileStream var to one BinaryReader as shown below: FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read) BinaryReader br = new BinaryReader(fs) From there forward, I'm lost.

  • Delete document with an empty ID

    - by Damien MATHIEU
    Hello, I have a CouchDB database in production. One of the documents has been edited (in Futon by an other developer). And it's lost it's ID (don't ask me how he did it). So now the document's id is an empty string, which makes it impossible to edit or delete via Futon. Is there a way I could hack into CouchDB to delete that document anyway ?

  • .net 3.5 message framing

    - by Rob
    We have message framing working by using a lengh prefix but using .NET 2.0 beginSend/BeginReceive. Is message framing any different in 3.5, if so how should we implement it using the new framework? Are there any useable examples out there which focus purely on message framing using 3.5? Many thanks

Trouble is I'm a Javascript noob :-(, so if you figure this out please share as much of your code as possible. Thanks much!

    - by LucasGuitar
    I have an application which I'm adding pictures and these are automatically converted to binary and stored in a single file. how can I save several images, I keep in an XML file start and size of each set of refente to an image byte. But it has several images in bytes, whenever I try to select a different set of bytes just opening the same image. I would like your help to be able to fix this and open different images. Code //Add Image private void btAddImage_Click(object sender, RoutedEventArgs e) { OpenFileDialog op = new OpenFileDialog(); op.Title = "Selecione a Imagem"; op.Filter = "All supported graphics|*.jpg;*.jpeg;*.png|" + "JPEG (*.jpg;*.jpeg)|*.jpg;*.jpeg|" + "Portable Network Graphic (*.png)|*.png"; if (op.ShowDialog() == true) { imgPatch.Source = new BitmapImage(new Uri(op.FileName)); txtName.Focus(); } } //Convert Image private void btConvertImage_Click(object sender, RoutedEventArgs e) { if (String.IsNullOrEmpty(txtName.Text)) { txtName.Focus(); MessageBox.Show("Preencha o Nome", "Error"); } else { save(ConvertFileToByteArray(op.FileName), txtName.Text); } } //Image to Byte Array private static byte[] ConvertFileToByteArray(String FilePath) { return File.ReadAllBytes(FilePath); } //Save Binary File and XML File public void save(byte[] img, string nome) { FileStream f; long ini, fin = img.Length; if (!File.Exists("Escudos.bcf")) { f = new FileStream("Escudos.bcf", FileMode.Create); ini = 0; } else { f = new FileStream("Escudos.bcf", FileMode.Append); ini = f.Length + 1; bin = new TestBinarySegment(); } bin.LoadAddSave("Escudos.xml", "Brasileiro", nome, ini, fin); BinaryWriter b = new BinaryWriter(f); b.Write(img); b.Close(); f.Dispose(); } //Load Image from Byte private void btLoad_Click(object sender, RoutedEventArgs e) { getImageFromByte(); } //Byte to Image public void getImageFromByte(int start, int length) { using (FileStream fs = new FileStream("Escudos.bcf", FileMode.Open)) { byte[] iba = new byte[fs.Length+1]; fs.Read(iba, start, length); Image image = new Image(); image.Source = BitmapFrame.Create(fs, BitmapCreateOptions.None, BitmapCacheOption.OnLoad); imgPatch2.Source = image.Source; } }

  • What are the implications of multi-tasking in iOS 4.0 for developers?

    - by MrDatabase
    I just watched this video from Apple that shows multi-tasking on the new iPhone (running iOS 4.0). What are the implications of multi-tasking to developers? Include both positives and negatives. For example what happens if the user decides to launch two resource-intensives apps at the same time, one of the apps crashes and progress in a game (for example) is lost. Should developers be considering this when writing apps for the new OS and phone?

  • How to resize an image smoothly (with resampling) using Windows API calls?

    - by Clay Nichols
    I need to resize images and resample them so they don't end up all jagged (I think that's called aliasing). I found some code (sorry, lost the link) that does this in pure VB6 code but it's a bit slow (2-5 seconds) and I'm displaying pictures in real time so I need something faster. I seem to recall seeing some examples of doing this with the GDI+ library. An example in VB6 would be ideal, but I can probably work with a simple example with Windows API calls in another language.

  • Javascript UI Toolkit

    - by Louis
    I'm looking for a light-weight UI toolkit written in Javascript (something like Swing) but I'd rather not use ExtJS because I fear that will slow things down tremendously. Are there any small UI toolkits out there that mainly focus on layouts?

  • get metadata from jpg, dng and arw raw files

    - by Daniel
    I was wondering if anyone new how to get access the metadata (the date in particular) from jpg, arw and dng files. I've recently lost the folder structure after a merge operation gone-bad and would like to rename the recovered files according to the metadata. I'm planning on creating a little C++ app to dig into each file and get the metadata. any input is appreciated. ( alternatively, if you know of an app that already does this I'd like to know :)

  • How did you choose a technology to specialize in

    - by Tomh
    I know it is kind of subjective, but as I've seen questions around like "How did you land your first job" etc. I thought it might be suitable. With so many technologies coming out these days and employers asking for specialists in those (no one is looking for generalists), I'm wondering how people here managed to pick one technology (or area) and focus on that. If this question is not suitable here, then where can I ask?

  • How to show printer properties/preferences dialog and save changes?

    - by Patrick Klug
    I can't figure out how to properly show the printer preference dialog of a given printer so that the user can change the printer settings. Most of the examples that I can find online manage to show the dialog but any changes the user might make are lost which makes it useless. Example: http://www.codeproject.com/KB/system/PrinterPropertiesWindow.aspx (I tried to change the code as suggested by BartJoy but that didn't fix it) Does anyone know how to do this properly?

  • Autorun a removable device in Linux

    - by Zloy Smiertniy
    I have a removable device setup so it autoruns when plugged into a Windows machine and pops up a message giving the owner's information, so it can be returned if lost. Is there a way to do this in Linux as well? It doesn't need to be complex, it can be an option in a right-click menu, or a splashscreen, or anything.

  • How to embed a google map with a changeable area?

    - by Tom
    I haven't worded this very well But basically, I'd like to embed a map on my site - but the area it shows will change. I've tried doing this, but it never seems to work as it will focus on the wrong area - the old area, rather than the new area. Basically, I'd like a google map code that uses $place as a location. Thanks.
