Hi,
you can set the appartment state for a thread using Thread.ApartmentState; you can do this only once per thread. You may not be able to do it for ThreadPool threads (and hence BackgroundWorkers), if so you will probably need an explicit Thread.

Thanks for your answer, Luc.
I've used the same pattern in another project successfully, in which the 'ShowProgress' method is located in the same form (i.e. there's no MDI parent form holding the ProgressBar). The only difference now is that the BackgroundWorker is started in a subform, trying to call the same method which is located in the MDI parents class. Do you think that's what kills my approach? I wonder if there's just an error somewhere in my code - or some rule like 'you can place this and that only in a module' which I haven't stumbled upon yet...

I am unaware of anything special to MDI, ad I don't use MDI.
If your CollectFrames method throws, give it a huge try-catch, show the full exception.ToString(), and watch the line numbers to pinpoint the problem. Chances are the problem is in "do other stuff".

Hello everybody,
I need some help with Parsing.
Here what I have to parse. I have to program it in VB MS Access:
'//*/Macro:911;Tests:#ADSLCustomerClass;Generates:146,147
BeginMacro911 ADSL 04 Fehlende Angaben, remplace Macro-326 cye 07.07.2003
Case_#ADSLCustomerClass
"002" : Mtext 146
"2" : Mtext 146
Else: MText 147
EndMacro911
The Real file has like 5000 more of these small texts I have to Parse...this is just 1 of the about 5000
Here what I have to do(I've done 1) and 2) of th first part , just don't know how to continue):
Description:
I need you to write a program using MS-Access which performs the following:
1) Display a “Switchboard” from which to select various functions. The switchboard will start with one button for one function called “Load Mac File”. The switchboard should be opened automatically when the access application is started.
2) Selecting Load Mac File from the switchboard should display a form where the user can browse to the “.mac” file to process.
a. The form should have a scrollable text box in which any progress or error messages are shown.
3) If the chosen .mac file can be opened:
a. Delete the contents of tblLoadableMacros
b. Read through the .mac file, parsing each macro and adding a new record about each to tblLoadableMacros
tblLoadableMacros should have the following fields:
• nID Integer, unique ID field, auto-generated
• nMacroNumber Integer, macro number. Unique value.
• sDescription Memo field. Macro description
• sTests Memo field, lists the values tested by the macro
• sGenerates Memo field, lists the macro text or values generated by the macro
• sMacro Memo field, contains the actual macro script
The attached .mac file is the file we want to parse. It is a text file, can be viewed with Notepad and contains macro script definitions. Here are two example scripts:
'//*/Macro:911;Tests:#ADSLCustomerClass;Generates:146,147
BeginMacro911 ADSL 04 Fehlende Angaben, remplace Macro-326 cye 07.07.2003
Case_#ADSLCustomerClass
"002" : Mtext 146
"2" : Mtext 146
Else: MText 147
EndMacro911
'//*/Macro:912;Tests:#ADSLCustomerClass;Generates:149,150
BeginMacro912 ADSL 01 neu Mindestvertragsdauer, remplace Macro-328 cye 07.07.2003
Case_#ADSLCustomerClass
"002" : Mtext 149
"2" : Mtext 149
Else: MText 150
EndMacro912
In the example of macro 911, your program should perform the following:
1) Read until you find a line which starts with “'//*/Macro:”. From that line of text, do the following:
a. Add a new record to tblLoadableMacros
b. Take the number after //*/Macro: and save it in the new record in nMacroNumber
c. Take the text between “Tests:” and the next semi-colon and store it in sTests. Trim white space.
d. Take the text after “Generates:” up to the end of line and store it in sGenerates. Trim white space.
2) Using the nMacroNumber parsed previously (e.g.: 911), read ahead until you find its BeginMacro line (e.g.: BeginMacro911). From THAT line, if there is any text after the BeginMacro keyword, do the following:
a. Take all text following the keyword (e.g.: BeginMacro911).
b. Remove any leading/trailing white space
c. Store the remaining text in sDescription
3) Scan all lines until you find the matching EndMacro keyword (e.g.: EndMacro912). Everything between (but not including) the BeginMacro and EndMacro lines is stored in sMacro
4) Store the new record.
5) Repeat from 1) until all macros have been read.
You’ll want to show error/progress messages as you go. Some examples:
• Parsing Macro 911…
• Stored Macro 911
• Error storing Macro 911: <error text>
• Did not find matching EndMacro911 keyword
• Warning: Macro 911 has no ‘Tests’ keyword.
• 127 Macros loaded. 5 Errors Encountered.
• Etc.
If someone could please help me I'd be so grateful, If you want to contact me through MSN Messenger (homedog6@hotmail.com) or Yahoo messenger (g_size18@yahoo.de) please ADD ME!
Hope this information helps
Regards Michael

Hi,
people on CodeProject are glad to offer advice, or help in solving a specific problem someone has with his code.
We do not just "help" by doing your work, i.e. the basic rule is: you do your work, we do ours. So do you have a specific question, instead of a project description?

First off all thank you for replying!
Secondly, since I'm new here I didn't know 
Well see I just don't know how to start!
as mention I have to parse that part of text but have no idea how to start.
If you could just like give me the beginning of how top start

ahhh yeah what i forgot to write was
in the first message it shows:
I need you to program...
I didn't mean you as in YOU GUYS
it's an E-Mail from my boss and he was referring that YOU to ME
|

Hi,
you would need File.OpenText, and String.StartsWith, and String.Substring, and many more.
I would stay away from Regex as this seems simple string manipulations.
Is this your first VB.NET app? Buy and study a book then.

First, this is never going to happen. Noone cares about your email addresses unless they're a spam bot.
Second, this is simple string manipulation. You can either look for those keywords and seperation characters in the line you get from the file or use a Regular Expression to do some of the parsing. Using a RegEx is MUCH harder to do if you don't know how to do simple string manipulations though. You know those functions, Mid, Left, Right??? Start with those to see what you can do.
This reeks of either homework or paid work. If it's paid work, refund the customers money and tell them you're not qualified to do this. If it's homework, you have to write the code. Noone here is going to write it for you.

I'm just asking for some help, since to chat online in a messenger is faster.
and I've been on yor site and haven't found what I've been looking for 
|
|
|
|
|
You start by reading the file, line by line.
|
|
|
|
|
I just don't know how to parse, can't you like send me an example how to parse so I atleast have a start?
|
|
|
|
|
I don't have any examples.
All you're doing is grabbing a section of the line and comparing it to what you're looking for, like:
If Left(lineFromFile, 9) = "Something" Then

Hi All,
Can any one help me in how to format the command for Run method in script ?
i have tried different way in giving input for Run method but it doent work , can any one look into below code
Below code is doing a XCopy for source to destination .
Set oShell = CreateObject("WScript.Shell")
RetVal = oShell.Run("""C:\Program Files\XYZ\ABC\XCopy.exe"" ""C:\Program Files\XYZ\ABC\staging\Advance NDC\utility\vvv.txt"" ""C:\Program Files\XYZ\ABC\utility\vvv.txt"" / s / q / y", 2, True)
|
|
|
|
|
IT doesn work because you're putting spaces between the forward slashes and the commands.
You've got: (BTW: I hope you have XCOPY.EXE in that folder you specified!)
"...XCopy.exe" "C:\..." "C:\..." / s / q / y"
When it should be:
"...XCopy.exe" "C:\..." "C:\..." /s /q /y"

Thanks for pointing out .

Well this is my third post resulting from this project I'm working on, which is taking me right out of my comfort zone!
I'm trying to replicate the behaviour of a server application we have which controls various display screens around the building over the network. The application itself is overly complex for our admin staff to use and I want to make my own which replicates just one small function of the original with a very simple UI. I think the networking side is fairly simple but although I'm quite experienced with vb.net I've never delved into the networking side of things before and it's a whole new scary world.
Up until now I've successfully got my version to broadcast a UDP packet with the required data, to which the display screens respond with an ICMP echo request. My server automatically replies to the echo (I didn't code that, the machine just does it). After that the client starts sending TCP packets in attempt to register itself with the server, and now that's where I'm stuck.
The client is sending a packet which apparently has no data but does have the SYN flag set to 1 and contains various 'options' (I'm getting this from a packet sniffer). When the real application receives that packet it responds with its own packet with the SYN flag as 1 and the ACK flag as 1, as well as the same options. However, because I haven't got the real application running my server machine just responds with a TCP packet with ACK=1 and RST=1, and no options.
My question is how do I code in vb.net the receipt of these packets from the client and respond with the correct flags and options? There are some good tutorials online for coding client/server communications using the Sockets class and I've got as far as I have by following these but none of them explain how to set flags and such. I suspect what I'm trying to do is at a lower level. Do I even need to manually create these packets?
I'm a bit out of my depth so any help would be very gratefully received!
|
|
|
|
|
Without seeing anything else in those packets, I'm guessing that the client is opening a TCP connection with the server on a certain port.
|
|
|
|
|
Yes, I think it is. But how do I get my application to respond in the same way as the one I'm copying does and allow the connection to be made? Once the server has returned a packet with the syn=1 flag it sends another packet telling the client that it was registered successfully.
|
|
|
|
|
I have no idea. But, what you describe sounds exactly like the client opening a connection to the server using TCP. What port number is used would be in the packet. Without seeing the packet data, it's almost impossible to say what's going on. You really can't look at one or two packets, but at a group of packets in the conversion to figure out what is really happening.
|
|
|
|
|
Alright, well it seems as if the TCP connection is being established now. The next packet that the client sends contains 26 bytes of data, which I've intercepted and read with a packet sniffer. My VB code receives this package and I've written it to display what's received, but it doesn't show the whole lot, for some reason. While the packet sniffer shows that the packet data contains the client name I only get the first four or five bytes of data displayed from my VB code. The rest seems to be ignored, even though a line I've written in to count the number of bytes indicates that the whole lot is being received. I've used a 'Do While' loop to make sure that the buffer is empty before displaying the data but still I only get those few bytes. Any idea why the packet sniffer is intercepting data in the packet which my application isn't receiving/displaying?

hi,
i have data grid view with 4 column the second and third combobox column type its bounded to different table related between them (it like category in 2nd column and subcategory in 3rd column).
my question: how to get value of Column third from main in second column?

Uhhh, what? This makes no sense at all.
|
|
|
|

What the OP is trying to do is when the user makes a selection from the combobox in column 2, the combobox in column3 should only show the options for that selection.
I'm not sure that it is possible though, as, for columns, the data source is set for the whole column, not just for one cell/combobox. So any change to the datasource for column3 will change any previous selections.

If that is indeed the case, I would normally break editing a single record like that out to a seperate form. It's a lot easier that way.
Come to think of it, I just about never let users edit directly in the grid...
