By buying a PDF library, finding a free one that works, or by writing your own converter.

I'm speechless. Please re-read my post. You need to buy a library, or find a library, or write a library. The end. There's no 'basic idea' I could put into a forum reply, except perhaps to type 'buy PDF library VB.NET' into google. Atalasoft has one.

Christian already answered this. You need to either buy some converter software, or find a free version on the web. Search google and you will find many possibilities. If you wish to do it yourself through programming then you need to get a copy of the latest PDF specifications from the Adobe website. Either way it requires some small effort on your part.

Hello All

I have my requirement as follows.
I have a MSAccess table with 4 columns(of text type)and another column of Oletype. I have programmed in VB.NET such that a query will returns a dataTable with all the columns from that table
What im trying is to put those contents on a word document with all the columns. For which I have tried to loop through the contents of dataTable and tried to attach all those values of all columns to a string and then I have added that string to a WordDocument Bookmark as shown below.

oDoc.Bookmarks(

"Questions").Range.Text = qest

But Im unable to get that image which was stored in database column in the above fashion. so can anybody suggest a solution for my problem

Thanks in advance

First, is an image a String?? Obviously, not. So this one line of code is not going to do it. You have to add the image to the document seperately. How do you do that?? i have no idea. I don't normally do Office Interop and am not very familiar with the Word Object Model.

A quick Google for "vb.net insert image into word document" reveals this list of examples[^].

I agree that image is not an string ofcourse its obviously not. But what I was trying to explain is my requirement was like ...... I will explain it again

My MSAccesstable is having 5 columns of which 5th column is an image(it will be a small image like an icon etc and which was saved with the help of binary array i.e. after converting the image into a binary and then inserting that binary data into a oleobject type column) and rest are text columns. I have to get the contents of the table based on a query into a DataTable and then I have to place the content of the DataTable on a plain word document row by row

So what exactly I want is how to add that fifth column which is an image onto a word document

hi,
i want to have a program which can read specific excell cell. i am using VB2008.

for example, the user will have to enter the row and column and a messagebox will pop up with the result.

for example:
row : b
column: 2

the value in b2 will have to pop up in a messagebox.

thanks

Send Hex code by UDP

phil241529-Sep-09 6:02

Hello,

I'm pretty au fait with VB.NET but a complete novice to programming anything to do with networking. I'm trying to replicate the behaviour of one small part of an application we have so that I can build my own application which will be much simpler for our staff to use to perform that one function. The application is a server program.

Anyway, using various network sniffers I've identified the packets that the application sends. It seems that when it starts up it broadcasts a UDP packet over the network, and then the clients respond with ICMP echos, after which further TCP packets are sent to the clients. Well, I'm stuck at the first hurdle!

I need, to begin with, to replicate that initial UDP broadcast. Using .NET and lots of Googling I've been able to produce code which will send a UDP packet to the right IP and port. What I'm struggling with is the data of the packet. Because I have the packet as captured in SoftPerfect Network Protocol Analyser (much more user-friendly than Wireshark for my money) I know exactly what the packet should look like and I can even copy the hex of the original packet.

I can't then simply stick this hex code into a string and send it over UDP, it doesn't work. Presumably it needs to be in some kind of array, but all the references I can find to this online seem to involve CONVERTING a string to hex or hex to bytes. Surely since I already have the hex no conversion should be necessary? I just want to send it exactly as it is! When I did convert it to a byte array (if that's the right term, this is very new to me) and then sent it the network sniffer picked it up and the data in the packet was very different and much longer than the original one I'm trying to replicate.

Any help or advice would be greatly appreciated, from general tips about replicating network packets to actual code I can copy!

Thanks in advance.

All packet data is just an arrray of bytes. Since you have the value of every byte, all you have to do is recreate that data in an array. It's that data that is going to get sent in the packet. Even if you supply a String, each character in the string if converted to a byte or set of bytes and sent as part of the packet. You have to values for each byte, they're just presented to you in Hexadecimal form.

Hi,

there is nothing in TCP/IP or UDP that uses hex. It is all bytes, representing numbers; numbers aren't decimal or hex or octal, they are just a bunch of bits. Hex/decimal/octal is a human way to look at numbers, and it only exists as a string. Your sniffer is getting bytes, and showing them to you using a hex string (because that has a fixed length of 2 characters per byte), you should read each 2-character hex number as one byte value.

So if your sniffer sees "12CD" that would be two bytes, one with hex representation "12" (hence decimal value 18), and one "CD" (i.e. 205). So you would need a 2-element byte array, initialize it with 18 and 205 (or &12H and &CDH) and send it.

Smile | :)

That's really useful, I think I understand now, thank you. But given what you've said what code would I need to actually convert my long string of hex code into a byte array that I can send by UDP?
