VS 2008 Proper Syntax To Identify A Text Document For SAVEAS Method?
Dec 10, 2009Using 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?

Proper Syntax For Comm Port Comunication
Dec 31, 2009Now I know whats going to happen, I will post a request for code syntax and one of the admins is going to say that I need to post the code I already have. The code I already have is irrelevant to what i wish to do. So, continuing on; I have a micro controller that i wish to send commands to it in HEX data type. Communication is via the serial port RS232. (well technically its through the USB to serial converter)Steps:
1) Sending a "001" tells the micro controller to await instructions as to what to set the duty cycle to
2) The data that follows i.e." 050, 010, 185 " will be added to 400 (by the micro controller) to come up with a duty cycle based on a 10 bit resolution of 0-1024. I am only going to be using the range of 401- ~500.
I can communicate with the micro controller via hyper terminal. Using the Alt + #keys method I can transmit data to the micro controller, and this is what i with to do with vb.net.[code]

View 9 RepliesVS 2008 Proper Use Of Resources For A Class?
Jun 8, 2010I 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 might want the first vendor to be a different color - or be bold.

VS 2008 How Many Proper Payloads Server Received
Aug 24, 2009I 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]
View 39 RepliesVS 2008 Proper Way To Pause/resume A Thread?
Oct 6, 2011I 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?
VS 2008 - Displaying Proper Columns In Console Game?
Jan 17, 2010I'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).

VS 2008 .net And Sql 2005 Syntax?
Feb 12, 2010I am using vb.net 2008 and sql 2005. I am writing a program to translate data from one database to another. Basically I have two dataGridViews, the original data is automatically populated to the first and on clicking the "Translate" button the second dataGridView is filled with the translated information. I am having trouble with the syntax of passing a value from the original dataGridView to SQL and returning the 'id' of the translated data table. For instance, the original has colors stored as "Blue" "Green" etc The new tables now have unique ID's with the color name as attributes. I need to basically be able to pass dgvOriginal.rows(i).cells("color").value to a stored procedure and get the "id" field of that color. Here is what I have so far.

VS 2008 Syntax Clarification If Not (x And Y) =?
Sep 9, 2009I would need some clarification on a syntax : could someone tell me why some people in their code use the following :
If Not (xxx And yyy) = 0 Then
'code
End if
instead of
If xxx = true Then
'code
End if
As an exemple : In a code I use for a listview Item Ownerdraw, it sure works like this :
If Not (e.State And ListViewItemStates.Selected) = 0 Then
' draw the listview item code
End If
but not like this :
If e.State = ListViewItemStates.Selected Then
