Compare 2 Large Size Xml Files?

Jan 29, 2010

I 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.

Dec 16, 2009

Within our application, some of the object's text are effected by users with "Large font" turned on under Control Panel>>Graphic Properties. I can't determine what is the trigger to this behavior. I have many forms including TableLayoutPanels, ComponentOne Sizers, some objects with DOCK=Fill, and AUTOSIZE=TRUE. I wrote a simple Hello World form, and it is not impacted by the "large font" setting.

Copying Large Files And Determining File Size Mid Copy?

Oct 31, 2011

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

Load Large CSV File Into Database?

Oct 14, 2009

I'm trying to load a large CSV file into a Microsoft SQL Server Compact 3.5 database. I've tried using the following: Using MyReader As New Microsoft.VisualBasic.FileIO.TextFieldParser("filename.txt") MyReader.TextFieldType = FileIO.FieldType.Delimited MyReader.SetDelimiters(",")Then splitting the data with MyReader.ReadFields() etc, before using this data to add rows to a dataset in a database table in my project. However, my CSV files are very large, at above 9.5 million rows, and this takes forever, if the computer doesn't crash also. Does anyone have a better idea for what to do? I would like the CSV file to be loaded into the database table, to enable me to sort it, and undertake some querys and maths. The CSV data structure is:2,193,761.40000000000012,43,1510.22,8,1929.60000000000012,22,2564.52,22,2791.70000000000032,19,2971.6000000000004

Slow Form Load (has Large Number Of Controls)

Nov 9, 2010

I wrote last week about a problem with an MDI program that had a large number of forms (each with a large number of controls on it) that was "sluggish" in loading and in switching between the child forms.I've attached an example program in VS2008 (though the actual app is VB2010)Rather than show the hardware control application with all of the text fields, and picture boxes acting as indicators, I made a simple program to show the point. This is exaggerated as this just loads 2000 or so text boxes on a form. In the real app I have ~ 200 assorted controls per form of picture boxes, scroll bars, text boxes, labels etc. Also, there is a large full screen .jpeg as the back ground of each form. All are generated at run time and are placed on the form in the New call of each form. (as in the sample attached)main issue seems to be the methodology I use to switch between child forms. I make the current form .visible = false, and the next.visible = true. I have used this as it "keeps the place" on each page if the user has scrolled or is looking at one section of the form. When the next form .visible = true happens I see the controls added in a "machine gun" fashion instead of all at once.

Large Database File (mdb) Takes Time To Load In .net So Alternative?

Feb 8, 2011

I have 4k records in access database. And one of the field value contains ~100 lines each so and one other field has ~25 lines. So total database size reaches ~30MB and it takes lot of time 15-20 seconds to load the database in vb.net using odbc [URL]..and updating of any other small fields also takes time due to database being large

So as an alternative I used rtf file (txt files were not preserving all the newline characters). So these file are around 5-10kb only. But for 4k records and 2 fields I have now 8k files. And copying of these 8k rtf files is taking huge time for 5MB transfer it takes an hour or so.So is there any other alternative for storage of this data. So that it will be portable and easily loaded/accessed/updated from vb.net?

I need to load a large txt file that is in a fixed width format. There are over 45K lines, so speed is important.I need to load one of the fields into a dropdown box and have another field (label) display the text of another field in the related line.I could import the file to an access db if needed, but would rather not as i also want the txt file to update from a link on a regular bases. So having it in a DB would be more work to process that part.[code]

File I/O And Registry :: AVI Header - Program To Download And Play AVI Files The Files Are Large In Size And Long Time Wise

Dec 11, 2011

I 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.

VS 2005 Dataset Xml Load?

With one xml file it loads the schema and data just fine, but with another xml file it only loads the schema and not the data. There's no error thrown - just no data loaded.

Anybody have any ideas? I've attached the .xml file for your review. I would have attached the .xsd but the system wouldn't allow it.

Forms :: Progress Bar And Load Dataset?

Dec 17, 2009

so what I want to do should be pretty simple. I've been following the examples found here Using the BackgroundWorker Component - VBForums . I've been successful, but I'm not smart enough to put it in my project.

What I'd like to happen is this

1. I hit a button to load data from a dataset....

2. have a progress bar show until this action is complete.

The main problem is that I can't figure out how to tie the "progress bar" to the action of "pulling the dataset"

I'm sure this is a crazy question for you all, but hey...

Would I put all of the coding in the button_Click sub?

Load Xml String Into Dataset/datatable?

Mar 27, 2009

I have returned xml data in a variable and need to loop through the returned xml and pull certain data from select nodes.

I was thinking the best way would be to load into a dataset (or datatable) and loop through that.

I also have the xmlschema. What's the best way to code this?

I thought I could do something like so but it gives me the following error: DataTable 'newdt' does not match to any DataTable in source.
