Hi Dave
Thank you for your answer. That sounds like the best solution to me. But again we have a limitation. We only have the posibility to run a web application, because the application it should be possible to move the application just by copying the aspx, dlls, and so to another webserver, and i should run again.
So we need a way to do it within the web application.
Best regards and merry christmas

On your ASP.NET application, on the app start, create a timer that ticks every, e.g., 5 minutes, and does whatever you need. This way your page won't "hang" while doing its work.
Just be sure to take care of synchronization to avoid problems when a page request comes and the work is still half-done (e.g., generate a temporary file, and when it's done, rename it to its final name).
I don't see dead pixels anymore...
Yes, even I am blogging now!

I have just read somewhere else, that i can't besure on that the timer is called after the specified milliseconds. Because of its priority to the requests made.
I need to be sure that the XML Doc is loaded every 5 minutes precise, no mather what load the server must be experiencing.
Can I be sure of that?

What is "precise"? Will a few ms make a difference? Often, this warning is made because of multimedia applications, where a few ms would mean skipped frames and/or a poor visual experience. In your case, it seems, you can trust timers, no one would care if a timer is fired with a delay of a few ms.

Sorry for my English
your right.. a few Ms will not matter at all.
I will try the timer
Thank you very much for your time. I wish you a merry Christmas.

I got a web server that has to host both 1.1 and 2.0 webapps. I can run the 2.0 project fine on my local machine which also has 1.1 and 2.0 installed, but when trying to do so on the server i get a parser error message. Its win 2003 server, my local machine is win xp.
What i've tried:
Created a new separate app pool for 2.0 projects.
Going to cmd and /v2.050727 and updated the scriptmap for only the 2.0 webpage (aspnet_regiis.exe) and with certain parameters.
Can anyone help me?
Thanks
/Andreas

I solved it.
When right clicking solution and pressing publish website, i had to uncheck "allow this precompiled site to be updateable". Either that or just debug as usual and also upload all the cs-files (which i deleted before since they wasnt used in 1.1).

I am trying to develop a class or function which takes a process ID, process Name, or a process object (doesn't really matter) and pauses or suspends the process. I know this is possible because my firewall (NVidia) can stop a program's exucution in its tracks, then resume after you allow traffic on the port. Additionally, the ProcessExplorer utility (http://www.sysinternals.com/Utilities/ProcessExplorer.html) provides this functionality.
My application is to pause a legacy instrumentation program which can crash very predictably if certain "conditions" aren't just so... If I could pause or suspend it while doing some housecleaning, I could keep it running fine. I thought this would be a very simple project!!!
At this point, I can enumerate the running processes, gather their IDs and any other relevant info. I tried to enumerate the threads involved in the process, then use the thread class to .sleep or .suspend. However, the type processthread cannot be converted to a system.threading.thread! I have found a C++ project (which I can only partially decipher) here: http://www.codeguru.com/forum/archive/index.php/t-210917.html, which appears to "encapsulate" the process into a debug event for pausing. Perhaps this a way to go, but I dont' know exactly how to use it? I can compile it, run it, and it works, but after the process is resumed, the console app scales to using 100% of the processor. Perhaps if I could make it an assembly I can pass it as a function... Perhaps there are some Windows API functions that would work?
Any help would be appreciated!
Thanks,
TOm

Actually, this will be a very complex project.
What you're doing is actually writing a type of debugger. The only thing you're going to support, though, is breaking the code so it stops running, then resuming it. Just like you do in Visual Studio while debugging your own applications.
You can try to gleen some information from this[^] little project.

Dave, thanks for the response - I am realizing your first statement is right on the money! Thanks for the URL - I hadn't yet seen that. I'm guessing this debugger is in "regular" basic? I have also found a debugger in managed code (for .NET 2.0) on MSDN. I can understand C# OK, but it takes me some time so I'm trying to see if it has the functionality I'm looking for. It's a bit confusing as the gui is built as an assembly and I haven't figured out how to instantiate it with the proper parameters. Lack of experience in this area is slowing me down (I'm a scientist, not a professional programmer!). I have a colleage who compiled the code I listed above as a function (dll) and I can call it and pause a running process ID. Getting it to resume is still a problem as the function goes out of scope before I pass resume to it. Unfortunatly, I don't know C++ so it's hard to create a class, use it and debug. You can never know enough!!!
Thanks again. Tom

The best place to ask would be in the forum at the bottom of the page that the article you read this on. The author would most likely know, or perhaps it has already been anwered there.

This can't be this difficult! I created 2 datagridviews where dg1 displays the parent table and dg2 the child table. Selecting and updating records is not a problem. The problem comes when I try to insert records.
I'm using MySQL 4 and Visual Studio 2005. I write in C#. I'm fairly new to C# and the whole .NET "thing" so I don't know if this is the right board but I figured I'd give it a shot.
If I want to insert a new record, I have to insert the parent record first. Update it. Close the app. Re-launch it. And then I can insert my child records in the recently created parent record. Also, only one new parent record at a time. I know this is ridiculous but it's the only way I can insert to the db.
Any ideas?
MySQL db:
Parent table: tbl_parent
id int(10) not null auto_increment,
name varchar(40),
primary key(id)
Child table: tbl_child
id int(10) not null auto_increment,
ref_id int(10),
name varchar(40),
cost float(4,2),
primary key(id),
foreign key(ref_id) references tbl_parent(id)
on update cascade
on delete cascade

Hi,
I'm working on a project that may require us to display a WinForm-based control in an ASP page. I have found examples of how to do so -- Raul Alonzo's article, for example, was very helpful: http://www.codeproject.com/cs/miscctrl/htmlwincontrol.asp[^]
I have been able to make this work using VS 2003 and the 1.1 Framework. This project will be done with VS 2005 and the 2.0 Framework, though, so I'm trying to do it there as well. The problem I'm having is that the control simply refuses to display. I do not get an error message or the little control icon, just an empty box.
Here is the Object tag I have in my ASP:
<object id="WFTControl" classid="Bin/WindowsCalendar.dll#WindowsUC.HelloWorld" style="width: 570px; height: 431px">
The HelloWorld control is simply a C# user control with a single button that, when pressed, changes its text to "Hello World".
Has anyone else tried this under 2.0? Is there something different I need to do?
Thanks in advance,
Doug

hi,
i'm trying to get values of the properties with property info (pi) class. if statement controls the pi.CanRead,
if pi.CanRead then
pi.GetValue(obj, nothing)
end if
(this is just an example)
it's working properly except "FileIOPermissionAttribute.ViewAndModify" and "FileIOPermissionAttribute.All"
it gives error on these two property "The 'get' method is not supported on this property." but it supports...
how can i fix this problem? thanks all..
|
|
|
|
|
Hi,
I don't know (and couldn't find even I searched hard) the ViewAndModify property but the All property if FileIOPermissionAttribute just throws a NotSupportedException in its getter implementation (you can see this using reflector on it).
This is probably because when you set All you implicitely set the values for Append, PathDiscovery, Read and Write to the same value. The All getter would have a problem when those properties would have different values.

Hi,
I am converting a ContextMenu from an existing app to ContextMenuStrip. I got around the problem of not having a Clone method handy, but I haven't found a way to implement the DefaultItem behavior that came with the old MenuItems.
Any suggestions would be appreciated.
Thanks

Hallo
i need to open some forms of a VB6 application from a .NET one; i have written both, so i have the source code and know the source names of the forms.
What should i do?
Are the forms accessible via their source code names? Eg. in a way like Form1.show etc.
Thanks in advance
|
|
|
|
|
The two apps don't know anything about each other. The forms in one are not going to be available to the other at all, let alone by the names you used in the source code.
What are you really trying to do with this?

ok thxalot for your feedback.
the situation is that i have a large VB6 application running, and i'd need to implement new forms/new functions that would be easier to code in .NET, or at least possible only in .NET. But i'd like the user to have the impression to use only one application: i.e. the VB6 app still run in foreground while the .NET runs in background and its forms are shown only when needed, or viceversa or something like that.
|
|
|
|
|
If you compile your VB6 application as an ActiveX Exe you can implement a public function in a public class which opens your form.
It should be no problem to convert your project if it isn't already an ActiveX Exe project.
After this you can bind your exe in the .net application and use the class to open the form.

Hi
I've been asked to associate a file extension to my program, so that
the user can double.click a .aaa file and my programs starts
immediatly reciving the file name and path as command line
parameter.
How can I do it in installation (or via code)
Ciao
Marco

You should create a registry key. If you're using fw 1.1 you can use the OpenNetCF Library to do this.
Creating a file extension association should then be the same like doing it for windows.
