Posting Small Bits Of Data
Feb 23, 2010
Is there another way to easily make a POST request in .NET other than the WebRequest class? I have a very, VERY small piece of data I need to post: password=theword but WebRequest randomly, and I mean randomly, drops the data when posting to my server. I've tested it by using a chunk of code from my server that dumps the request to a console, and I can that the client is sometimes sending and sometimes not sending the POST data.The code that I'm using that uses WebRequest works in another project, when talking to IIS. The server being talked to (a minimal web server in another system) responds properly every time I POST data to it through Firefox. I've got a function in the same project that fires off a GET request, and that works. It just seems like my POST function isn't completing the transaction...something I've noticed in the past when asking WebRequest to handle small strings.[code]

I am currently working on a form that performs several calculations and then submits it to a sql server. I was able to post test data to SQL when using command.CommandText = "<SQL insert statement, inserted values 'test, 5'>" followed by command.ExecuteNonQuery(). But now when i try to submit data using variables i get an "A first chance exception of type System.Data.SqlClient.SqlException' occurred in System.Data.dll"I am not a programmer, so sorry if my code looks a bit rudimentary...

I'm trying to figure out how to calculate the lower 7 bits and 7-13 bits of two hex numbers.
Here is some example c code, just need this in vb.net:
serialBytes[2] = 0x64 & 0x7F; // Second byte holds the lower 7 bits of target.
serialBytes[3] = (0x64 >> 7) & 0x7F; // Third data byte holds the bits 7-13 of target
The 0x7F is a constant so the only number that changes based off input is the 0x64.

Background: My VB .Net application is a back-end solution that works with a proprietary Linux-based middle-ware messaging architecture developed by our company. My application references to the middle-ware DLLs, obtains connectivity, and subscribes to specific broadcasts with the middle-ware. When the broadcasts are received, it handles processes them and inserts/updates certain tables in a database. To do so, it has specific notification classes to handle each type of broadcast. These classes adhere to the inheritance model imposed by the middle-ware DLLs.

What's the deal with those 23 unused bits in the Decimal data type? You know, there's the 96-bit integer portion, then 16 unused bits, then 8 bits for the exponent (which can only be 0 through 28, so doesn't even use all 8 bits), then 7 more unused bits, then the sign bit [URL]...

I have an application that uses Dataset.WriteXML to create a small backup before data is syncronized to a data store (less than a meg).This application has worked well for 5 years now, and all of a sudden with the installation of XML 6.0 SP2 the XML document is not working correctly.I have multiple tables within a Dataset (Company, Contact, Notes, etc...)When WriteXML is called, the first table should be Company, however, the first table is being named Contact with the Company Data in it. The Notes table is being called Contact and so forth. In other words it's not giving the correct names to the tables in the XML File.This appears to be a bug, which is causing great distress on all the companies who have been using this program.

I have written a small project that saves data in a data set, this part works fine, but I have some errors with the code I have written for importing excel data to the datagridview and exporting data from the data grid view.
This is a test project for me to learn how to do this stuff, so I will post the code for the entire project so you can see what I have done from start to finish.

This error has me completely baffled. There is no indication (that I ca FinD as to what field won't handle the information. Heres the situation:I am using an Accees query to insert a new record in a table with 49 fields. Of these fields, 1 is an integer, 7 are booleans and the other 41 are text fields. The text fields represent either Time of Day or a Timespan.
My field sizes are:
For time of day 8 digits(example 08:00 AM)
For a time span 5 digits(example 03:30) I will never exceed 2 digits for
hours
I have checked every field in the dtatbase and they are all as noted. I am at a loss as to how to proceed.

Is it possible to use VB code to code an application that can merge Hex data from a small (50kb) .dat file with the hex data from another small (50kb) file? This would require designating specific offsets, which I can pre-program, but If I could have user input this would be preferred.
Example.
Hex_1.dat
00 00 00 00 00 11 11 11 11 11 (Offset = 5)
Hex_2.dat
22 22 22 22 22 33 33 33 33 33 (To offset = 5)
Result file
Result.dat
11 11 11 11 11 22 22 22 22 22

Updating an Excel file from a dataset seems to work fine. But if I have text that's longer than 255 characters then I get the error above.I've been working on this for a couple of hours and I haven't gotten anywhere. I've tried messing with the connection string and changing a registry setting, but no luck.

i am writing an application that will need to store less than about 1mb of data. this data will be read and edited by the user. this data will be very simple ascii data. the application is in vb.net on a windows-form. the data will be stored locally on the person's computer.i have several questions.what kind of encryption method should i use to store the data? the user wants something that is not too powerful, but not too simple either.how should i store the data? why not just write it to some file and encrypt it using some medium encryption method?is application settings data encrypted? perhaps i can store it that way? is it suitable to store about 1mb in application setting data? how would i do this? which variable would i use?

So, I have a little issue.. I can't currently explain it using the software I'm developing because it's "internal"... So I'm going to describe it as an email serverAnd the email server has a fair number of email accounts, and I want to save the accounts emailFor development, I've been saving it all in a list of a structure (this sounds worse than it is, the data actually is no more than 120 bytes per "email")

I will be using .Net to communicate with a small unit that outputs data via a serial port. I have used an application that monitors the data between an application and this little box. What I see is functions such as IRP_MJ_CREATE, IRP_MJ_READ, etc. At first I thought I needed to build functions and I would send these via the serial port (a novice thought) now I see that the above functions are part of the Windows Driver Kit. So is it true that I call these functions in my code and then the underlying drivers communicate to the serial port and the approppriate data is seen at the serial port. So for .Net (VB) I need to find and use the appropriate functions and communicate to the serial port.

I have a small database program that gets data from csv file, I created a function that formats the font color of textboxes based on dates and values.
CODE:
I place this in text changed event and I have a problem implementing it, because the date conversion will not take place until the data is loaded. The second part works but not the first(Date) part.
I can create a button and use its click event to format the text boxes just fine, however i wanted the text boxes to be formatted on the fly . The problem is no matter where i call the function the date conversion wont work.

I want to create small database which handles Student Attendance Record it will store the roll calls of students on daily basis that teachers collect from the students in the class on paper and then later transfer it on computer .So my database Must contain Month, Year, Program (BCS, BIT, MS, MCS, MIT etc) Batch (1st, 2nd etc) and Subject (English, Math, Geography etc)
Suppose I want to Search for the Attendance Sheet of any month, year, Program, Batch or Subject, it returns me the required dataSo i come up with the Datadase which includes 5 dimension tables and one fact tableDimension Tables1. Student (StudentID, Name, other Attributes)2. Program (Program_Name, other Attributes)3. Date (Date, Week, Month, Year)4. Batch (Batch_Number, Description)5. Subject (Subject_Name, other Attributes)Fact TableAttendanceTable ( StudentID, Program, Date, Batch, Subject, Status)but the problem come when certain columns are repeating again and again which is time consuming for database operator and shows inconsistent behaviour of database.
Look at it: my Fact table would be like this [code]....
problems:1. The StudentId is repeating which shouldn't (Primary Key),2.It wastes a lot of time coz i'm repeating the data again and again Like Program, Date and Batch which shouldn't be in consistent Databases.

I understand how to post a value back to a standard asp.net page and how to then use that value at the serverside:
Request.Form("id_of_posted_value_goes_here")
How do I do the same in a webservice (asmx)? I can't use the line above because it says:
Name 'Request' is not declared.

I'm using Visual Studio 2005 and ASP. NET 2.0 with this program. This is written in VB.net
Right now, we've got a Gridview that is embedded and databound into another gridview. The 2nd Gridview is hidden by default and expanded by the user. Within the 2nd gridview are several DropDownLists. The problem is that these DropDownLists are not firing the OnSelectedIndexChanged functon nor AutoPostback whenever I change the selecteditem.[code]...

I would like to search an online (internet) database and import the result in my own Windows program. As I understand from reading and searching I first have to do a get from the default (search) page to get the cookies for instance and then do a post providing the filled input fields and adding the previously collected cookies. So far getting the information seems to work but submitting the data back to get the actual search result doesn't seem to work. This is what I have so far: [code]Anybody that can point me in the right direction? I my assumption correct that I first have to do a Get and then Post the correct data back?
