(A) I have a MFC static library that defines some classes that do some speciffic work.
(B) I have a C++ CLR console application that uses the library from A. Both are compiled to use MFC as shared library. The target of this project is to prove that the code in A is working in .NET, and the code from A can be reused.
When running B, it crashes with this error:
[...........]
An unhandled exception of type 'System.AccessViolationException' occurred in Unknown Module.
Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
[...........]
The Output console contains:
[...........]
'PipeManagerDotNetTesterServer.exe' (Managed): Loaded 'C:\WINDOWS\assembly\GAC_MSIL\System\2.0.0.0__b77a5c561934e089\System.dll', No symbols loaded.
First-chance exception at 0x78375508 (mfc80ud.dll) in PipeManagerDotNetTesterServer.exe: 0xC0000005: Access violation reading location 0x00000000.
A first chance exception of type 'System.AccessViolationException' occurred in Unknown Module.
An unhandled exception of type 'System.AccessViolationException' occurred in Unknown Module.
Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
[...........]
Any ideas ? because the code in A was tested in an usual(no .NET) C++ console application with MFC support and it works well.
thanks

This questiom should be asked in the Managed C++ forum.

How would I translate from one .NET language to another programmtically (prefrably counting MSIL as a language, but not neccassarily).
I have searched through the CodeDOM class, but nothing in there seems helpful.
Thanks in advanced,
Fahad

There is probably better ways to do this, but one method I have used to translate from VB.NET to C# is by using Lutz Roeder's brilliant Reflector. This is anyway a very useful program. In it, you can load a compiled assembly and dissamble classes in the language of your choice. It supports C#, Visual Basic, C++ and Chrome.
You can download Reflector from here: http://www.aisto.com/roeder/dotnet/[^]

I know about reflector. I was asking how to do this in my own programs (I am sure I read somewhere that it is possible)

can anyone help me give suggestion in making setup with trial version
|
|
|
|
|
Take a copy of the existing code, and remove/limit some of the features. </obvious>
Have the installer automatically install the parts that are the same, then ask for a serial number. If none is provided, install the trial version of the rest, otherwise install the full version.
To stop this from being bypassed, have the full version check a license file.
(do not make the trial do this, as a faked file may unlock some things).
A good license file would be a mac address, full name, organisation and time and date of install, all md5'ed with a key that only you (and your program) knows.

Alternatively, allow the user a time limit to which they use the application for.
You'll have to implement some hack-proof techniques though, because the most obvious hack would be to turn back your computer time.

Hi,
I have regular expression for a phone number. The rules i want are; 10 and only 10 digits and any characters in between.
eg.
"0123456789"
"(01)23456789"
"(01)23 456 789
"0123 456 789
"0 1 2 3 4 5 6 7 8 9"
"01 23 45 67 89"
are all acceptable
the regex i have is:
"([^0-9]{0,}[0-9][^0-9]{0,}){10}"
everything works ok except for detecting numbers that are too long (i.e. more than ten characters). I already have a work-around for this, i am just interested to know how to achieve the same thing in a regex.
cheers to you.

handle keypress event
count the pressed in chars. if =10 e.Handled = true.
Hope this helps
cheers, geri

so I would do sg like
<br />
int count=0;<br />
if(Char.IsNumber(e.KeyChar))<br />
{<br />
count++;<br />
}<br />
if(count==10)<br />
e.Handled=true;
<br />
& count-- if user deletes.....(so presses like: e.KeyChar = '\u0008' >> backspace, i guess )

Hi,
thanks for the reply, but my question was specifically to do with regular expressions.
thanks anyway.
|
|
|
|
|
Put $ at the end:
"([^0-9]{0,}[0-9][^0-9]{0,}){10}$"
Regards

|

This would have no effect, the beginning is not limited.
"^([^0-9]{0,}[0-9][^0-9]{0,}){10}$" fixes this.
(in your regex, the number 12345678901 would have caused the underlined part to match.
|
|
|
|
|
oops, absolutly right
Regards
|
|
|
|
|
Thanks, that works just as i need it.
I had tried the $ character at the end, but not in conjunction with ^.
Thanks to Mabo42 to the reply as well.

can i install .net frame work in windows 98
|
|
|
|
|
according to MSDN:
you can install 1.1 redist
cheers, geri

IIRC I started with .NET 1.0 on Win98.
I am pretty sure later .NET versions (2.0 and above) don't support Win95/98/Me

I was just working on a WinForms applet for which I want variable transparency of the client area.
What I want is the window to have a TrackBar to adjust the transparency of the client area while the TrackBar, border, and title bar stay opaque.
I know how to make the client area completely transparent.
And I know how to make the entire window variably transparent.
But I haven't yet found a way to make just the client area variably transparent.
Any ideas?
Hmmm... I suppose I could stack two forms...

I am trying to bind a ListView/TreeView w/e to a Data Source I've created from Visual Studio for the project and would like to know if and how it would be possible to bind solely using XAML.
As an idea, let's say we have appName, appName.dataSetFromMySQLviaODBC as the data set, with tableAdapter and tableColumn as the only column, any way to, using only XAML, no cs code that's "user" written, bind the data there to a ListView?
And if it's not too much of a stretch, considering it's probably quite easy to find if I poke around, anything special to do to make the data update in the ListView mirror the database changes? Or is it at least possible?
|

My knowledge of WPF is quite limited, having only looked into it in the last two weeks. But, from what I've found, using ODBC as a data source, no, you cannot do this using only XAML. I think you need to provide the code to grab the data so the XAML has something to bind to.
I could be wrong though...
By the way, using ODBC is quite pointless if your using SQL Server. Use the SQL Server specific provider if you want your SQL code to run faster and offer more flexibility.
Dexterus wrote: anything special to do to make the data update in the ListView mirror the database changes?
Only if you have code that goes and gets the changes. Youe code doesn't automagically know that the database has changed without it changing it itself.

Eh, tried to do something fast-ish so I used what I had, an ODBC connection string
My WPF experience extends to today and the examples I've found around about this DB binding were pretty much using the same thing, a DataSet.
So either I have not found the correct one that VS creates when I create a Data Source (code it auto-magically created to work that data source was slightly hard to read) and I should use as Provider or maybe context or it simply doesn't create a DataSet instance. This last thing would mean it turns into the same, initialize connection, get and fill that all examples I've found do, only they do it a lot cleaner than the "wizard" way.
As for the auto-update was thinking maybe data sources would have some sort of flag or something that would signal the change and it auto-update based on that and someone would know about that. It's not an issue though, manual labor works also.
PS: Would there be a better place for this post? As this is my first one I am somewhat unfamiliar with the exact structure. Switching to another board would keep this one clean of unrelated stuff and make my question slightly more visible to people that spend more time browsing that other board.
