VS 2008 How Many Proper Payloads Server Received
Aug 24, 2009
I took a look at System.Security.Cryptography.MD5 class about using a checksum for a UDP program i am making.Basically i want to use it, to ensure the server is receiving what the client sends it, in a way that the server can make note of it receiving properly without having the client keep track of how many proper payloads the server received. The reason i need a checksum is because the client is sending a random hex payload, so i cant have the server predict what it should receive the same way as i have it working with the sequence number.I dont fully understand how i could implement this to my code. I believe i should make a public property in my packet class, but im having trouble implementing it with the way i coded my program. [code]

I found one problem Windows Server 2008. please refer the following code. it gives me the "ieplorer.exe" while i am running this code in XP or 2003, but while I am running this code in Windows Server 2008 it is not giving me the proper result. it gives me Explorer.EXE" insted "ieplorer.exe".before run this command you have to add reference of shdocvw.dll in your project. i am using the VB 6.0
Dim IE As SHDocVw.InternetExplorer
Dim MainIE as SHDocVw.InternetExplorer
Dim sws As SHDocVw.ShellWindows
[code].....

Hey guys, I am trying to send data from client to server (encrypted) and the string sent from the client is not the same as recieved from the server. I've been killing my brain for hours to get this to work but I cant manage. Im converting everything to Base64 string.
Client:
Public Sub SendMessage(ByVal msg As String)
Try
SyncLock myclient.GetStream
sw = New IO.StreamWriter(myclient.GetStream)

I am trying to use AJAX UpdateProgress to display the loading image when the zip file is being created but get the following error:
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Detals: Error parsing near 'PK'.

I'm currently working on a project that populates a database with CAD document info from approx 20 engineers / draftsmen in an engineering office.I have the program functionality working on my computer. However, I would like to install this on the network and begin doing some addiitonal testing and debugging.
I'm unsure about the proper way to install the database and sql server express on the network. My program, which sends the info to the database, will be installed locally on each persons computer. Of course, the database file will be in a location on the network that everyone has access to.I'm assuming I should install the SQL Server Express on the network server as well. How do I setup the server for the SQL express?For example, when I installed it on my computer, the default server name was "Brian-HPSQLSERVER".How do I specify a new server name when installing the software?

I just wanted to confirm my reading -- this is the number of bytes that is put in the buffer before the data received event is triggered, correct? And it's ONLY for that purpose?

In my serial port application, I have my code -
Private Sub SerialPort_DataReceived(ByVal sender As System.Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort.DataReceived
Dim cnt2 As Byte
[code]....
For some packets I sent, "Error Data Received" came up. I checked BytesReceived, it was 0. My question is: since SerialPort_DataReceived processes data received, data was supposed to be received. Why the number of bytes I read was zero? BTW, when is this event accessed? it is accessed when any number of bytes received or the whole packet received?

I am not sure of the proper, or best, way to use Settings and Resources. For now I use the default project wide My.Settings and My.Resources. I have a class that I would like to reuse in other projects, so adding project wide settings or resources in each project doesn't sound proper, nor does creating constants and variables within the class itself.I'm guessing there is a way to give a class its own resource file, and maybe even settings file, but I'm not sure how to do it. I tried adding a resource file with the same name (but with .resx extension) and I got a weird error saying I was trying to edit a resource that is apart of another project. I continued, but it didn't seem to be what I wanted and I wasn't sure how to access that new resource.

I want to display some text for a user - blocks of text about "vendors" - that can be scrolled.
I might want the first vendor to be a different color - or be bold.
I might want certain fields in the "text blurb" about each vendor to be bold - or underlined - or a different color.
In VB6 I would have used a RTB - would that still be the solution??

I have a thread running on my application that checks a database every so often to decide whether or not to update nodes in a treeview.
Each treeview node represents a document and I have an open button that opens the document for the user.
When the document is opened, I wanted to suspend the thread that refreshes the node list until the document is closed.
I have MyThread.Suspend and MyThread.Resume. But the document viewer is on another thread.
I created functions for suspending/resuming the thread in the application. I have delegates in the viewer to call those functions from another thread. But I'm still getting an Error. "Thread is not user-suspended. Cannot be resumed" or something of the like.
But I realize that Suspend and resume are obsolete functions, so what class or objects should I be looking into and if it didn't take up too much of your time, a small example as well?

I've been trying to publish some software for 2 days. At first, I received an error about frontpage extensions not being installed so I installed them, only to screwup the ht.access file on my site and lose my web site for 5 hours.
I had an email this morning from Lunarpages saying they installed the extensions, recoded the ht.access and even tested frontpage on it. SO -- I tried again this morning and still received "the components for the frontpage extensions are not installed". ?
AND --I must be missing something and looked everywhere in VB.NET (options etc) but how in the heck can you publish something directly to your website (I used the wizard and setup all the publish options) and NOT be prompted for your user ID and password? Obviously, VB.NET has it's own ftp program.

I'm making a console game that shows some data:
#: Item Name Item Slot Cost Item Price
in that order. The thing I want to do is to make it come out in nice even columns...but I can't seem to make it do that. It comes it out in nasty uneven rows that don't look attractive...
Basically, here's what it looks like now:
1. Sword Slots: 2 Price: $40
2. W. Stick Slots: 4 Price: $1
I want to get each column to line up nicely with the other (since I control the size name).

Using Excel Automation classes I am seeking to save an Excel file as a delimited text file. The examples given in the MSDN library refer to versions older than Express 2008 with (apparently) different syntax options for FileFormat.Based on the snippet shown, I get a COM exception error (800A03EC). Other variations produce the same error.
Am I improperly applying the Automation features?

I am using Visual Basic express to create a serial interface to a multi-room audio controller. I have started by creating a form that can connect to the controller and I can receive data from the Controller and display Zone status, volume etc in corresponding texts box thaks to help from Stanav and Tassa in my previous thread.
My next problem is to do with receiving lots of data from the serial port and my application getting out of sync. This is mainly caused by turning the volum control as each time it is turned a little bit the controller sends out the new status of the Zone being effected
eg
****Turning Volume knob on Zone 1***
Status returned from Controller:
#Z01PWRON,SRC3,VOL05<CR>

I have developed a VB.NET program using a strongly typed dataset. This dataset has its connection to a SQL Server 2008 R2. The software should now be additionally used offline. The database should be exported to a *.sdf database. If no connection to the SQL server is produced, the software have to try to connect to the *.sdf database.I would like to achieve:
1. Export the data in the SQL Server 2008 R2 database to a local *.sdf file.
2. This *.sdf file has to work as an alternate connection string in the strongly typed dataset.

We are currently using Access 97 as our database. This resides on the remote farm server (which is a Windows 2008 R2 server). We are using a front end vb6 exe which accesses the back end data.Occasionally we are getting corruption to our database and we have to make sure everyone exits the software to allow us to repair/compact it. There are 2 physical servers, each running 2 virtual machines. When the user logs onto the farm using RDP, they go to one of these 4 virtual machines.We are getting all kinds of corruption, some where # characters have been inserted into the top of one table, some where the indexes are corrupted, and some where access needs to repair the database.
