is there a way to extract all the text from a Word Document in VB.NET without actually openning the file? I'm asking since it is a very time and memory consuming operation to open a word document, select all, assign it to a variable and the close the file.I have a routine the opens all emails in a mailbox and analyses the body and subject object for regular expressions. I would like to do the same for the attachment, if it's in Word. if it's not possible to extract without openning the file, can anyone give me the best way to do it so that the routine doesn't destroy my server memorywise?
View 2 RepliesI've been getting wierd errors due to what appears to be compiler side errors, based on a corrupted compile that the compiler keeps using until i do something drastic like copy an entire module or function into noteback text editor, save my code, restart VB 2010, and paste it back in.[code]you may ask yourself, why do i even bother having the select case statement in the loop?c1 never gets high enough in the loop for your select case statement do anything (case: 99999, moreover u make c1 = itself, so there is no change in c1's value) The answer is that at one point i was making the select case statement do something, but when i tried to delete the entire select case statement, execution would simply fall through the loop.The for loop would only execute once.It would only do this with "optimizations enabled" outside of the debugger.Inside the debugger it worked fine, but every time outside of the debugger it would only execute once UNLESS i kept the meaningless select case statement in there.
Then, not wanting to see it there any more, i tried deleting the entire function (copying the text to notepad), recompiled (delete the calling line for the function), saved, exited, restarted systems (tried restarting system many times b4, but not b4 doing all this), opened VB, delete the select case statement out of notepad, copied the edited function from notepad to VB, recompiled and magically it finally worked.Understanding a little about optimization at machine lvl coding it appears the next c1 was optimized out by the compiler, instead using the end select statement to loop back to the top of the for loop.However, upon deleting the select case statement, it never reintroduced a loop back at the "next c1" statement, casuing execution to fall through.i've noticed this error occur about half dozen times (in other forms: by error i mean the comiler saving an optimization, but when the code that prompted the optimization is deleted, the compiler is not able to properly undo the optimization) while building my program, and my suggestion (rather than hunting down each of these errors), is to force the compiler to rethink the logic of of the program from scratch (which is what i thought it did already everytime i hit compile), but these experiments make me think its saving an error some where that only copying the function to note-pad and back again could make it purge.
I seem to be having some problems with my projects for school. I use Visual Studio 2010 on Windows 7 Professional at school and I do my homework on Visual Studio 2010 with WinXP SP3 (fully updated) at home. When I move the project files back and forth the projects become corrupted. I get the following problems.Form controls move or properties do not work as they are specified in the property box such as:
Link label with the property set to hoverUnderline text.Labels that move position.I also get x86 errors that show up during a Debug or Build, such as:x86 Only one reference to Resources is allowed.I need to be able to work on both my WinXP SP3 (fully updated) machine at home and use the schools Win7 Professional machine to both complete projects and get my project graded.

I write text to a file using StreamWriter as shown below several times a second. The problem I have is that sometimes these files are left blank after my program has crashed or the computer has crashed. I've done several searches on the internet without any results other then writing to a second file, copying over the file and then deleting the extra file when done. If this method doesn't have any error modes it still appears to be less then a beautiful solution. (What happens if the computer crashes when writing over the original file?)Is there a more secure method for writing the text file that doesn't leave it vulnerable? This happens way too often. I never find errors related to file writing. I really want this code to be reliable enough that I could just pull the plug on the computer
Try
Dim mSW As IO.StreamWriter = New IO.StreamWriter(countFile, False)
mSW.WriteLine(CStr(totalCount))

I just published this simple console application that is supposed to show a textbox with the value of a setting called "userID" with value 1001. This works like a charm. Now what I need is to change this value outside the editor, from notepad etc. When I open the application a lot in there is non-sence etc. but with a quick (ctrl + F) I found the value 1001, and changed this to some other integer.
I ran the application again, and it failed, didn't even give any userful error-message. At a point I tried just opening a newly published non-corrupted version of the application, didn't change anything, then saved from notepad, and it were also corrupted. It seems like notepad can't open some characters or something. Do I need to publish the application in some specific text-unicode language or something? I use vb.net for this

I've been having a very odd problem when creating zip files in vb.net. They are ok when I run the code and save the file locally. However, if I run the program via remote desktop, and then save locally, the zip file is corrupted, and will not open (message "cannot open file:it does not appear to be a valid archive").I have tried opening it as a txt file, and found that there is a load of HTML at the bottom of the corrupt version, that the non-corrupt version does not have. Anyone got any idea how this extra HTML might have got there?[code]

And on another scenario If two Packets are clashed together in one buffer should I always try to Peek and see if the Next byte after the CRC is a SOH to see if there is more Bytes and an whole another command to start Parsing and then take action?

This is a problem with MS Access, but I can't seem to find an MS Access Forum, so I'm asking it here.I have a large table of just one field. The field type is Byte. I use CTRL C and CTRL V to make a copy of the table.I then compare the Source and Destination tables and lo and behold they are different at about record number 8 million.I also tried an Append Query to append to an empty table (I haven't tried a Make Table query).But, similar corruption.The source and destination tables do not end up the same. The Record where the failure occurs varies, but it is always greater than 8 million.I tried this on MS Access 2002 and 2010 (both with an Access 2002 database).
View 1 RepliesAfter inserting an user control and double clicking on it, a stub with the default event should appear.
If I don't define what the default event is and I don't assign any attributes to any events or properties, it works, and it generates the stub for the UserControl.Load event (the default default event).
But if I set some attributes for the properties and events and/or I define the default event, the stub generated is corrupted. Here is an example of what I should get:
Private Sub FaceSelector_OnSelect(SelectedObjects As System.Collections.ObjectModel.Collection(Of Object)) Handles FaceSelector.OnSelect
End Sub
And this is what I actually get: Private Sub SketchSelector_OnSelect( SelectedObjects As System.Collections.ObjectModel.Collection`1)
End Sub
Private Sub FaceSelector_OnSelect( SelectedObjects As System.Collections.ObjectModel.Collection`1)
End Sub
In this case I had 5 user controls, I double clicked on one of them, and I got 2 corrupted stubs.
Sometimes the corrupted stubs are generated when I change some properties of other controls in the form, or the form itself. For example I resize the form, the error window doesn't show any errors, hit F5 to compile and run, and get a syntax error.
I tried to track the problem down by removing each event/property attribute/xml description, one by one, many times I thought I found the culprit, but after 10 minutes the problem popped up again.
