  • Get file size of BufferedImage before writing the data

    - by David
    I'm working on a Java program that needs to send an image (preferably in PNG format, though I could perhaps use another format if necessary) over the network. The logical way to do this is, of course, to first send the length of the PNG image data, then the data itself. Problem: I don't see any method in ImageIO or anywhere else that will give me the length of the image data. Does this exist somewhere in the Java 1.6 standard library? I know I could just write it to a ByteArrayOutputStream and get the length of the resulting array, but before resorting that I wanted to make sure I'm not missing something built in. And besides, that makes an extra copy of the image data, which I'd rather not do if it's not necessary.

  • TSQL Writing into a Temporary Table from Dynamic SQL

    - by Jeff
    Consider the following code: SET @SQL1 = 'SELECT * INTO #temp WHERE ...' exec(@SQL1) SELECT * from #temp (this line throws an error that #temp doesn't exist) Apparently this is because the exec command spins off a separate session and #temp is local to that session. I can use a global temporary table ##temp, but then I have to come up with a naming scheme to avoid collisions. What do you all recommend?

  • Writing a unique identifier to script?

    - by dannycab
    I'd like to write a subscript that adds a unique identifier (machine time) to a script everytime that it runs. However, each time I edit the script (in IDLE) the indetifiers are over-written. Is there a elegant way of doing this. The script that I wrote appears below. import os, time f = open('sys_time_append.py','r') lines = f.readlines() f.close() fout = open('sys_time_append.py','w') for thisline in lines: fout.write(thisline) fout.write('\n#'+str(time.time())+' s r\n') fout.close() Thanks for any help.

  • Writing to an xml file with xmllite?

    - by Chris
    I have an xml file which holds a set of "game" nodes (which contain details about saved gameplay, as you'd save your game on any console game). All of this is contained within a "games" root node. I'm implementing save functionality to this xml file and wish to be able to append or overwrite a "game" node and its child nodes within the "games" root node. How can this be accomplished with xmllite.dll?

  • java.lang.NoClassDefFoundError thrown with my own packages in Android 1.5

    - by TiGer
    Hi, I have developed an application which has several packages within it's project... A class in one of those packages is called right away in the first line of code, which throws the dreaded java.lang.NoClassDefFoundError error... I don't get it, the package simply is within the project, and it works fine on my Android 1.6 device, but won't work with my 1.5 device... I do have to say that the project was originally set for 1.6, but then I changed the within the manifest from 4 to 3... Is that bad practice ? Or maybe it has nothing to do with the platform version ? Also I do get these lines as wel from the DDMS : 05-04 17:24:59.921: WARN/dalvikvm(2041): VFY: unable to resolve static field 2 (MANUFACTURER) in Landroid/os/Build; 05-04 17:24:59.921: WARN/dalvikvm(2041): VFY: rejecting opcode 0x62 at 0x0034 05-04 17:24:59.921: WARN/dalvikvm(2041): VFY: rejected Lmobilaria/android/managementModule/Management;.getDeviceSpecifics ()V 05-04 17:24:59.921: WARN/dalvikvm(2041): Verifier rejected class Lmobilaria/android/managementModule/Management; Thats the ManagementModule which also tries to retrieve several info-fields of the device itself... Again, this works just fine on the 1.6 device, even though thats a development device whilst my 1.5 device is a non-development device...

  • Writing photos (and other things) to disk and getting them later in iphone

    - by ebabchick
    I'm trying to write an image to disk: NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsPath = [paths objectAtIndex:0]; NSString* savePath = [documentsPath stringByAppendingPathComponent:@"photo"]; BOOL result = [data writeToFile:savePath atomically:YES]; if(result) NSLog(@"Save of photo success!"); Then, later, I try to retrieve for a table view cell image: NSData* getPhoto = [NSData dataWithContentsOfFile:[leaf content]]; UIImage* myImage = [UIImage imageWithData:getPhoto]; cell.imageView.image = myImage; Yes, I checked to make sure the [leaf content] returns the same NSString as savePath. What else could be the problem? [NSData dataWithContentsOfFile:[leaf content]]; returns nil.... Thanks guys

  • C: writing the following code into functions

    - by donok
    Dear respected programmers. Please could you help me (again) on how to put the following code into functions for my program. I have read on-line and understand how functions work but when I do it myself it all goes pear shaped/wrong(I am such a noob). Please could you help with how to for example to write the code below into functions.(like opening the input file). My attempt: void outputFile(int argc, char **argv) { /* Check that the output file doesnt exist */ if (stat(argv[argc-1], &inode) != -1) { printf("Warning: The file %s already exists. Not going to overwrite\n", argv[argc-1]); return -1; } /*Opening ouput files*/ file_desc_out = open(argv[i],O_CREAT | O_WRONLY | O_EXCL , S_IRUSR|S_IWUSR); if(file_desc_out == -1) { printf("Error: %s cannot be opened. \n",argv[i]); //insted of argv[2] have pointer i. return -1; } } Any help on how I would now reference to this in my program is appreciated thank you. I tried: ouputfile(but I cant figure out what goes here and why either).

  • Writing an AI for a turn-based board game

    - by Cyril
    Hi, i'm currently programming a board game (8x8) in which I need to develop an AI. I have read a lot of articles about AI in board games, minmax with or without alphabeta pruning, but I don't really know how to implements this, I don't know where to start... About my game, this is a turn-based game, each player has pieces on the board, they have to pick one and choose in moving this piece (1 or 2 cells max) or clone the piece (1 cell max). At the moment, I have a really stupid AI which choose a random piece then choose a random move to play... Could you please give me some clues, on how to implement this functionality ? Best regards

  • writing a shell script if statement to check for directory

    - by user1553248
    I need to write a script that will recreate my opt folder if it gets deleted when I remove a package from it. Here's a link to my previous post: dpkg remove to stop processes Now, the issue I'm running into could be better described here: http://lists.debian.org/debian-devel/2006/03/msg00242.html I was thinking of just adding a postrem script which checks if an opt directory exists, and if not, creates one. My experience with shell scripts is pretty limited though..

  • Writing Great Software

    - by 01010011
    Hi, I'm currently reading Head First's Object Oriented Analysis and Design. The book states that to write great software (i.e. software that is well-designed, well-coded, easy to maintain, reuse, and extend) you need to do three things: Firstly, make sure the software does everything the customer wants it to do Once step 1 is completed, apply Object Oriented principles and techniques to eliminate any duplicate code that might have slipped in Once steps 1 and 2 are complete, then apply design patterns to make sure the software is maintainable and reusable for years to come. My question is, do you follow these steps when developing great software? If not, what steps do you usually follow inorder to ensure it's well designed, well-coded, easy to maintain, reuse and extend?

  • Writing a script with the cmd prompt.

    - by Josh
    I'm trying to make a script that will place a list (in a .csv file) of processes that are running that take up more than 10 mb of RAM and shows the time + date the script was run. My teacher did this during his lecture but I can't remember how he did it. Just trying to figure out how to be better at IT. So my question is, can anyone help me with this? I don't even know where to start.

  • Writing a simple incrementer counter in rails

    - by Trip
    For every Card, I would like to attach a special number to them that increments by one. I assume I can do this all in the controller. def create @card = Card.new(params[:card]) @card.SpecNum = @card.SpecNum ++ ... end Or. I can be blatantly retarded. And maybe the best bet is to add an auto-incremement table to mysql. The problem is the number has to start at a specific number, 1020. Any ideas?

  • Creating our own APIs

    We need a bunch of APIs for our service and are looking at the job as being quite tedious for starting from scratch because we need strict user restrictions such as max queries and usage statistics. Are there any pre-made services or scripts for this already?

  • writing structs and classes to disk

    - by Phenom
    The following function writes a struct to a file. int btwrite(short rrn, BTPAGE *page_ptr) { long addr; addr = (long) rrn * (long) PAGESIZE + HEADERSIZE; lseek(btfd, addr, 0); return (write(btfd, page_ptr, PAGESIZE)); } The following is the struct. typedef struct { short keycount; /* number of keys in page */ int key[MAXKEYS]; /* the actual keys */ int value[MAXKEYS]; /* the actual values */ short child[MAXKEYS+1]; /* ptrs to rrns of descendants */ } BTPAGE; What would happen if I changed the struct to a class, would it still work the same? If I added class functions, would the size it takes up on disk increase?

  • Writing a script for reading many .csv files with similar filenames

    - by wahalulu
    I have several .csv files with similar filenames except a numeric month (i.e. 03_data.csv, 04_data.csv, 05_data.csv, etc.) that I'd like to read into R. I have two questions: Is there a function in R similar to MATLAB's varname and assignin that will let me create/declare a variable name within a function or loop that will allow me to read the respective .csv file - i.e. 03_data.csv into 03_data data.frame, etc.? I want to write a quick loop to do this because the filenames are similar. As an alternative, is it better to create one dataframe with the first file and then append the rest using a for loop? How would I do that?
