View 6 RepliesI like to compress the xmldata before the data is provided to the client as an excel file. I am trying to compress and deliver it as a .zip file. its not working Here's my code below. I tried compressing it, converting it to bytes etc etc. The issue with below code is, the XSL transformation is not happening properly and the output excel file is raw xml with some .net exception at the end. (that's what I see on the .xls file that's downloaded at the end) Before I started working on compression my below code was working fine that gives properly formatted excel file from the xml input. the excel file is so nice you can't even tell it was from XML.

View 5 RepliesI wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.
View 4 RepliesI have created an vb.net windows application. In the application i have 2 xml files (e.g., Pre.xml & Post.xml) & the 2 files are same structure.
My requirement is compare the pre & post xml files and get the differences between xml files. Like what are all the newly added nodes, removed nodes and modified nodes as well.
I tried with XmlDiffPatch.Dll, it is working for small size xml files, but in my case xml file size should be upto 100+ mb.

I'm using "My.Computer.FileSystem.CopyDirectory(...)" to copy large directories (30-50gb) from one mapped share folder to another. Using "FileInfo.length" to add up all file and subfolder sizes, determines the 'origin directory' size just fine. However, if I use the same method for determining the size of the 'destination directory', mid copy, it returns the full file size, despite the copy not yet being complete.I'm at a loss as to why, as this method works fine in testing, going from a local PC t

I have a bunch of 10 digit integers that I'm passing in a URL. Something like: "4294965286", "2292964213". They will always be positive and always be 10 digits. I'd like to compress those integers into the smallest possible form that can still be used in in a URL (aka letters and numbers are perfectly fine) and then uncompress them later. I've looked at using gzipstream but it creates larger strings, not shorter.

View 6 RepliesI have a system in VB.Net 2003, and that system takes a very long time to load. From the minute I click on the EXE, it takes one minute before the log in screen appear (P4 with 1GB RAM, no other application running). The size of the EXE is 33.2MB. I think the problem is the way I code the program, 1) I declare all the form as obj when I first load the system and I've got over a hundred forms. I try to load them as I need them but it does not work cause forms with sub form would give me an error. 2) I am using dataset as we know dataset is not very efficient but I don't know how else to connect to the database. Is there anything like ADODB in VB6?

View 1 RepliesHere's my scenario:
1) The user places a handful of image files into a given directory. Could be bmp's, jpg's, etc.
2) The images files will be saved into a 2nd "temp" directory and reduced down to a size reasonable for e mailing (ie. 200kb per file). I'm assuming they will end up as jpg's, so if they start out as bmp's they will need to be converted.If they start out as jpg's, and are just too big, they will need to be shrunk proportionately (ie. if they start out as 12 inches by 18 inches, they will end up as 6 x 9, or something like that).
I've found various bits of code on this forum (and others), but want to hear some opinions about the best way to go about it, assuming there might be as many as ten or twelve files that need to be manipulated. So should I read something into a memory stream (haven't tried that before), or create bitmap objects (seems slow?), etc.

View 5 RepliesI have a database application in which a user can add up to 6 pictures to each record. This pictures are not directly saved in the database but in a sub folder of the applicvation folder. Now, the problem is that lots of the pictures of users were taken on a digital camera with highest resolution - in these days it means that the picture files have a file size of 3MB.I would like to reduce the file size / resolution of the picture, so that the database can load and view this files more smoothly (I am not in need of a thumbnail preview, just want the pictures being a bit smaller).
The way pictures get attached / linked / 'inserted' to a database record is via OpenFileDialog. When a user selects a picture file it gets copied into the applications picture folder and renamed to the record ID of the actual record + number of the pic added.How could I reduce the picture size during adding it (OpenFileDialog / copying to folder)?

I have a big windows forms project I'm working on. This project has 3 pictures included as resource. I had 3 pictures of each 5mb, which resulted in a .exe file of 17mb. This had to be adressed, because thats a bit to much, so I downsized the pictures to about 100kb each. I've removed the big pictures, and inserted the new ones. But when I compile the project, the .exe file still is 17mb, and it won't get any smaller. I've tried to 'Clean Solution',

View 1 RepliesI'm making a presentation program. It's a bit like PowerPoint, but less complicated and for a different purpose.
All files used in the presentation (like images, texts and sounds) should be put into a single 'file-package'. This package should later be opened by my program, which should be able to use the files from the package. (Just like PowerPoint creates a single file with all images and sounds included, which can be loaded in PowerPoint on a different computer.)
Actual compression for the file is not really needed. It could be sort of like a tar-file.

View 4 RepliesI want to have a backup feature which takes about 7 txt files and compresses/packs them into one file. Then if required at a later stage I can unpack all 7 files from the packed file. I do not need any compression as such just to make one file from 7, then 7 from from that one, if you understand what I mean. I have read there are some native libraries in .NET Framework 2.0 called DeflateStream and GZipStream. Can these be used?
