HTTP 404 Not Found Error On Web Service Call, Only With Large Amount Of Data
Sep 2, 2011
I have a vb.net Windows application that calls a vb.net Web Service function. Both the vb.net application and Web Service have been in use for over 5 years and have worked well. The Windows App builds a text file consisting of a number of inserts into an Oracle table, followed by a call to an Oracle package. The Web Service call uploads the text file to the Web Server, loops through the statements in the text files and executes them. It then does a Select statement to put the resultant data in a string which is passed back to the calling program. We have both people on our local area network as well as external users where the call to the Web Server is over the internet.
The data string returned is the pricing for each of the lines inserted in the text file, separated by asterisks. Normal use of this call has anywhere from 1 to a few dozen lines, and the program works fine for this for both internal and external users.
Our problem right now is one external person is attempting to price a job with 491 individual line items. At first it would not price, whether the job was priced from a computer at the customers site or one of our internal people on the LAN. The problem turned out to be the timeout value was not long enough (it was set at 2 minutes, this job takes 5 minutes) so changing both the Timeout value in the Web Service call as well the httpRuntime executionTimeout value in the web.config file on the web server addressed the problem, but only for our internal users on the LAN. Our external customer wants to be able to price jobs of this size going forward, and I am at a loss as to why it errors on internet connected machines but not locally connected machines. Our customer is in New York, We are in Wisconsin, and I am able to recreate the error condition from my home computer.
The other thing is, if I create a VPN connection to our server from my computer at home, this job will price (again, it takes about 5 minutes) but if I disconnect the VPN connection, it gets an error after approximately 3 minutes, http 404: Not Found.The customer can otherwise price all of his other jobs with no problems, it's only this one, very large job that gets the error.

I'm searching the same title "Large amount of data in ComboBox" last 1 and half years but I could not get what I'm expecting! Here is my case, I have 20 thousand unique products, I just fill into dataset & bind only two columns in the combobox for searching & validating the product if it is exist in the product list or not.
1) I read about dataset but all articles are described "Dataset only for few records because it is sitting in-memory". If I fill few records (100 or 1000 products) into the dataset, how can I search & validate REMAINING (NOT FILLED) products?
2) Is there anyother way without filling into dataset and bind to combobox? Can anyone suggest me which is suitable for me?

I tried to follow this advice, but I still run out of memory.
[URL]
Basically, I am reading all the bytes of a 1 gb disk and I want to try and do a md5 hash on it. However, when following this example, my cryptostream gets too large a System out of memory exception.
Is there another way to do the md5 hash over some much data?
I am currently reading it into 10 million bytes arrays at a time. Can I hash the first array, and then use it as a seed for the next array, and so one, like you might do to a CRC32 calculation?

I have kind of a big quesstion...ok here goes...Usually if i understand it well...web services work in a way that i write a method to get some data from the database and then some other user/client adds a reference and calls my service and gets the data...now in my case i have to get the data and actually post it to the user/client in xml(in soap maybe) i guess....so here is what i do...
[Serializable]
public class MyClass
{ [SoapAttribute]
[code]....
So basically....I serialize it to xml(and soap) and convert it to string and then upload this string to the web service url...I just want to know if what i am doing is right?...i want to basically get the data convert it to soap xml and then send it over to the user's web service url...

Just a doubt: if I have large amount of image files for my app, is it ok to store them in the resource file ?
Will those files be saved in a single resource file ? Will that cause any problem to the performance of my app ? When I try to access a image file from the resource using code, will it load that file only into the memory or the entire image contents from the resource file ?

I'm loading an image, then getting size and such info from it, and loading the image into a picture box. Now it works and all, but I noticed it uses a large amount of memory. I'm doing: img = Image.FromFile(file)Where I load the image, 'file' being just a string containing path to an image on the hd. After that, I get the size and frame count (if any), and load it into a picture box: The image I've been testing with, is a 6600x5100 3.5MB JPEG, which can be downloaded from url...Watching task manager, when the app loads the image, it takes up about 104MB of memory. I've tried doing img.Dispose after the above line, but it brings up an error. If I put a button on the form with img.Dispose in it, and click it after app has loaded, it drops down to about 6MB of memory used. Loading the image directly into the picture box using .Load or .LoadAsync, after disposing img beforehand, still ends up with a huge amount of memory used.
So I'm wondering if theres a way to check if the picture box has fully loaded the img, so then I can Dispose the img and free up the memory. Or maybe a better way all together of loading an image into a picture box, and/or getting size & frame count, without having to use up that amount of memory before freeing.

I am making an inventory program in which there's an ItemMaster and Sales Form. Currently there are 15000 records of items(increasing daily). I want to display all the items in the sales form so that the user can select an item from the list for billing, and also in the itemmaster so that if the user wants to edit any item then he can select it from the list.
I can make a common list form for both sales and master, but i have to load the data from the database into the list every time the list is displayed(which is taking lot of time), so is there an better way to do it.

I'm looking for some advice on how to optimise the following process:App reads csv file.For each line in the file an XML message is created Each XML message is posted to a URL via a HTTPWebRequest This process was designed to handle low volumes of messages (up to about 200 at a time), un suprisingly thinks have changed and it is now expected to handle up to about 3000 at a time.
The code used to post the message is here: Public Function PostXml(ByVal XML As String) As HttpStatusCode
[Code]...
I am currently restricted to sending multiple messages due to restrictions elsewhere in the system. There is a noticable delay in responding to the request at the other end (the receiver) but this is outside my control. I am trying to ensure that the process of sending is as efficient as possible (external factors notwithstanding).

There is a very strange problem with a Windows Service I am working on that I would like to understand why it occurs. The service loops every 5 minutes and then within that loop it loops through keys containing webservice URLs that are numbered such as:
<add key="URL.1" value="http://dummy1.com/Service.asmx"/>
<add key="URL.2" value="http://dummy2.com/Service.asmx"/>
<add key="URL.3" value="http://dummy3.com/Service.asmx"/>
The code that does this check is:
If String.IsNullOrEmpty(AppSettings("OM." & intCount & ".Name").ToString) Then
When it hits a key that doesn't exist an exception is thrown and the service stops and waits for 5 minutes until the next loop.This usually works great but every week or two the Windows service will crash on that line without any Exception. The application log has a line from before that line but nothing after, none of the Try Catches are hit (the main one is catching the base "Exception" class).In the Event Log for Windows is the following:
Faulting application name: MyService.exe, version: 1.1.2.0, time stamp: 0x4fa22a24
Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319
Exception code: 0xe053534f
[code]....
The weird part is that this line of code is executing fine 300 times a day for at least a week which is around 2000 times before that one time it causes a full crash of the application. why this is occurring? I have changed that line of code to not rely on Exceptions and it has been working fine for a week now with no crash so could be something to do with too many Exceptions - maybe causing a stack overflow?

I am trying to develop an app that will export a large amount of zip files all of which have the same single file in them - simply named 'dw' (with no extension). They will all be in the same directory. I want the file 'dw' to be renamed to the zip file name + .tif. (I will actually eventually need for this to use the magic number to determine if the file is a .tif or a .rtf.) I have been able to get it to cycle through, if the file is NOT renamed. I seem to run into issues when I want the file renamed. It just creates the first .tif file and thats it. I think its actually just cycling through but everything is getting that same name. For the record i am not a programmer by trade, just trying to help with something at work - thus I know the code I have peiced together probably isn't 'by the book'

I have the following search code which works fine. However, I have an additional task to do, which is create a count function for the Record found or Record not found. Presently what it does is it searches and if a record is found it displays at the tooltip "Record Found" if not it says "Record Not found". However, sometimes you have 2 or more records. Therefore, the tooltip should say the exact amount of records found.. For example, 3 Records Found or even 5 Records Found. Also if only one record is found it says "Record Found" but if more it should display " 2 Records Found".

I'm attempting to consume a HTTP Basic Auth Secured PHP WebService using VB.NET. I've so far managed to get 100% perfect integration by adding it as a Web Reference and doing the following:
Dim Credentials = New System.Net.NetworkCredential("username", "password")
Dim CredentialCache = New System.Net.CredentialCache()
CredentialCache.Add(New Uri(MyWebService.Url), "Basic", Credentials)
MyWebService.Credentials = CredentialCache
MyWebService.PreAuthenticate = True
I can also successfully add the webservice as a 'Service Reference' and this also works fine, as long as i turn off all HTTP authentication on the SOAP server.
My problem is that I can't find any documented means of sending basic HTTP Auth Credentials when using Service References as opposed to 'Web References'
Am I right in my understanding that 'Web References' are a legacy method of Web Service consumption?

How do I wait on a port in the app?
