I'm trying to create an app that controls a BSS BLU-80 (DSP) through Ethernet. I've written a few basic programs in the past, but nothing that used sockets or even required calculating a checksum. One of the values I need to send has to be 24 bits. This one really has me scratching my head. From the manufacturer's docs:
[Code]...
error Public member 'Tables' on type 'ApplicationClass' not found when trying to create the table.The error occurs at the line

I have created an application in VB.net 2010, I have an SQL database that I want to gram some data from: Then Create a word document with that data and save it to a given location, this is what I got so far.
Process.Start("Outlook.exe")
Dim oApp As Outlook.Application
Dim oEmail As Outlook.MailItem
[Code].....
This gets the file and attaches it to an email. I have created another button that is called CreateReport_btn when this is clicked I want to get the last data from the sql database and insert it into a word document.
Im having a problem getting my calculations to work. I need to find the average letters per word.

I've wanting to generate a CRC16-X25 checksum in the form HiByte and LowByte. All the examples I've found by searching are either VB6 which uses functions and data types that are no longer supported or C, C++ etc. Does anyone have a simple VB.Net version? Speed is not an issue.
View 10 RepliesI have been trying to compute the checksum for a line of hex code. This is to create a hex file which will be loaded onto an embedded micro.Some of you guys may not know how this is done so very briefly:
a line of hex bytes:
: 10 01 00 00 21 46 01 36 01 21 47 01 36 00 7E FE 09 D2 19 01 40
The underlined bytes are taken and summed. (in this case the decimal 960). and the bold is the checksum Only the 8LSB (or single least significant byte) is needed to compute the checksum... which in this case, 960 = 03C0 in hex, so only C0 is needed.Two's complement is then taken:
step 1) logical not of C0 which is
step 2) add one (integer)
BIN...........DEC...HEX
[code]....
So here is the code I have been using: (quick mention that in the string passed, the hex bytes are all grouped together, there are no space characters)
Public Sub CreateLine(ByVal Data As String)
'Dim BDataArray(DataLength) As Byte
Dim IDataArray(Data.Length) As Integer
[code]....
where i get into trouble is where i commented 'i get into trouble'. My code works, but it's rather crude Now, in that line i first convert the hex value (string) "SChecksum" into an integer. I want to NOT this, so I get my step 2 from my explanation. However, the results appears to be a signed logical NOT. which gives me the wrong answer. My hashed togther version simply subtracts 256 before the not, in order to give me the correct answer.
Basically, I would love for someone to chime in and point out the flaws in my function, and push me towards figuring out the 'proper' way of doing this. Also I can't quite wrap my head around what would happen in the case a string were passed to my function that is over 16 bits, but I imagine I would have to subtract a larger value than 256, before doing the NOT in this case?(whilst we're on the subject of functions, I've used a 'sub', in which case should I used a sub, and which case should I use a function?).
I'm having a problem creating a function for calculating an average. I need to divide the sum of a column of integers by the number of rows in that column. These integers are generated by a datediff command and their values are assigned to textboxes in a report. The results can only be whole numbers, no decimal points.
I'm pretty new to this so if this is an obvious question please excuse my ignorance. If you need any more information to address my question please let me know.
I have a IF statement which is checking each row in the data table (for a match) and ELSE statement with commands which are executed if the If statement is not satisfied. Now I would like to write like so that it goes to the Else part BUT ONLY for values which are not satisfied in the IF statement. If I am more specific; I would like to calculate values if a match is found and just print them if it is not fond (usually there are both cases). Now the problem is the text that is marked red; if there is a match found I don't want it processed BUT if the match is found I do. How can I write that?

The application I support is creating an amalgamted Word document by copying couple of Word documents in one document right after each other. The problem is the format of the some of the fields of the document that gets appended is changed in amalgamated document while the amalgamated document is the copy of AppendDocument (imagine if we have one document to copy in the amalgamated document)

We have an interactive windows based application written in VB .Net 2010. It uses Word Object to display documents in MS Word. We have a form with a button. When the button is clicked we open the Word document and maximize the Word Windowstate. When we have the Visual Studio Tool running, the Word Document is maximized and has focus, even if we are running the exe from the bin folder outside of the tool. However, if Visual Studio is not running and we run the exe, focus remains on the original form window and the document stays in the task bar.
View 5 RepliesI have a string that can be anywhere from 1 to 8 digits long of which each character is a hex number (0-9, A-F) and each character isn't necessarily unique. I need to calculate all possible combinations. Is there a specific term for this type of calculation or combination? I need to learn how to write a program to "calculate" all the possible combinations.
View 2 RepliesI need to create a simple program that will calculate de price of the meal+the taxes aswell as the tip.
The prov taxe= 8,5%
the fed taxe = 8%
and the tip is 15%
I need to use const for this one.heres what i came up with:
Private Sub partie4_click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles partie4.Click
Dim repas As String
Dim sous_total As String

The user has to type the price of the meal and then it should calculate the price but for some reason instead of *8,5% it will do x*8.5.
Currently I was making a program that will store staff holidays, with a form they can fill out when they take some.The form has Holiday Start and Holiday Finish as 2 Date Fields.Also 7 Check boxes(Monday to Sunday) so they can tick which days they would normally work.The problem i have is then we need to know how many days are being taken, for example.[code]But they have ticked they only work Tuesdays and Thursdays this means they would have only took 2 days holiday.How could i calculate this say if an employee took 1 month?
View 2 RepliesI have developed a WinForm Application with VB.Net (VS2010) having Office 2010 Professional Installed, and it is 64-bit Windows 7 Platform. The program opens a .doc and .rtf format document, and attempts to save it in htm format. I am using following commands:

View 5 Repliesis there a way to get the raw data of a word file document object?
word = new Word.Application();doc = new Word.Document();
now, I open the word file, do some replace. save the file. I could open the file as raw binary file. but I'm thinking maybe there is a property that can get the raw the data? which property?
I am trying to calculate the difference between 2 times.
So far I have 4 labels.
Label1 = Current date and time.
Label2 = Contains the exact time that the application was last closed.
Label3 = Contains the exact time that the application was opened.
Label4 = I want this label to say how much time in seconds had elapsed between the application last being closed and the application being opened again, in other words the difference in seconds between label 2 and label 3.
Below is what I have done so far, but despite repeated efforts I can't seem to find a way of getting the time difference to show in label 4?

What would be the best approach for creating MS Word 2007 documents with vb.net that contains signature lines? I am currently in the planning phase of a project and I'm trying to gather some info. The idea would be to upgrade this program we have already developed(using vb.net) to generate .docx files that contain signature lines that are created progmatically. The signatures would be added later by the user through a workflow in SharePoint I just need to create the document with the lines. I have seen different tutorials on creating word docs, but not sure which method would be the best for what I'm doing. Where should I start looking?
Also, there doesnt seem to be too many tutorials on adding signatures line through code, more specifically how to automate the signature line setup. e.g. Who should sign, signers name, signers email address. How do I set these paramaters through code?
I am generating tables and writing them to word on the fly. I do not know how many tables there will be each time i write the data to word and the problem I am having is the second table is written inside the first cell of my first table. If there was a third table it is put inside the first cell of my second table.Is there a way to move the cursor out of the table? I have tried creating a new range with each table also but the same thing happens.I have also tried things like tbl.Range.InsertParagraphAfter()The closest I came was using the Relocate method, but this only worked for two tables.
View 3 RepliesI'm working with some very large files residing on P2 (Panasonic) cards. Part of the process we employ is to first generate a checksum of the file we are going to copy, then copy the file, then run a checksum on the file to confirm that it copied OK. The problem is, is that files are large (70 GB+) and take a long time to complete. It's an issue since we will eventually be dealing with thousands of these files.
I would like to find a faster way to generate the checksum other than using the System.Security.Cryptography.MD5CryptoServiceProvider I don't care if this means using a specialized hardware card, provided it works and is not to ungodly expensive. I would prefer to have a method of encoding that provided some feedback as to how far the process has gone along so I can display it like I do now.
The application is written in vb.net. I would prefer to be able to use it as component, library, reference within my application, but I'm willing to call an outside application if there is enough improvement in the speed of generating the checksum.
Needless to say, the checksum must be consistent and correct.
This comparison shows the different values of the known good checksum calculation (c#) as used by my client and what I 'hoped' was the vb.net equivalent. How can I get 405 rather than 513 as I currently do?
For i = 0 To length - 2 Step 1
cksum += sendFrameData(i + 5)

I need to convert a string to get a checksum as follows;
Checksum
The checksum is the 8 LSB (least significant bits) of a simple addition of all octets (note that a message type '30' is two octets with the values 33 hex and 30 hex) following the STX character and until the checksum field. Note that all separators will be included in the checksum, but the STX, checksum and the ETX will not be included.
Dim str as string = "01/00064/O/30/12345678/87654321////////48656C6C6F20576F726C64/"
This should result in checksum = "C2" What type of checksum is this? what should I Google for? CRC, MD5, hash ?
