Hi,
I vaguely remember either a CodeProject article or a discussion thread on this very topic,
I guess dated early 2007.
Bottom line is there is no .NET support for this, if you really need it, you have to figure
out the window hierarchy of all the components in an OpenFileDialog, then send some messages
to the button window that controls the list view. Not really simple to do.

hey guys, heres the deal. i got a few apps, running in production, but im constantly improving them. having to go from computer to computer and run the installer over and over (im using innosetup for the installer) i would like to incorporate some sort of auto update component. what would be the best approach towards this. should i keep the binaries on the svn server and somehow check against that and download the appropriate files and then somehow restart the app. or would it make more sense to somehow make the installer do the updating and just release 1 file? any input on the subject would be appreciated.

Any input? Really? What did you think of the input on the subject on the MSDN site[^]? Note that this information is so old it has been archived.

Yeah, you can do it manually like that; check some web server for updated version and pull those down as needed.
An alternative: .NET provides a built-in deployment mechanism called ClickOnce, which allows for automatic updates before starting your app, after running your app, or at any time via a single line of code. Read up on it here[^].

unfortunately, clickonce just isn't an option for me. i started to develop my own updater, however, im still puzzled about how it will update all the files (including the executable itself) when its still running, will i need to make this into a seperate application that replaces all the files and then starts up the main executable? also, id rather not have to keep two different sets of files, one on my developing machine and one on the server that the updates will be hosted at. i thought about maybe just downloading a setup file (which i already output for production) but im not sure if the installer (innosetup) will allow to "update/replace" files because as far as i know it just installs the app on a per version basis, so you can have your app version 1.1 and 1.2 installed at the same time. would it be feasible to somehow compress the update and have the program deflate the files?

I suppose the auto-update bit could be a different application, yeah. I've seen several applications like this.
Another possibility may be something like an application structure where your program is just a simple shell that never/rarely gets updated, and the rest of your application (the parts that get updated) are loaded like a plug-in, which can then be loaded/unloaded on demand through things like AppDomains.

hello
I'm looking how to start the default web browser with a given url from csharp
I can't believe how so "trivial" information is so hard to find
Thanks for any help
|
|
|
|
|
|
I found this !!
System.Diagnostics.Process.Start(@"myUrl");
|
|
|
|
|
|
Yes I did the same
But have a look on those results : the right answer is not so eaysy to find
And there are also real wrong method
Finaly, I do this
System.Diagnostics.Process.Start(@"myUrl");
It also have the advantage to automaticaly load the default browser
And I post the answer here for all those having the same question!!
|
|
|
|
|
Well, you'll never find anything with "myUrl". A url consists of something like "http://www.microsoft.com/" so if you pass the url in properly then you will find it run in the default browser.
|
|
|
|
|
Ok Ok
MyUrl was an example to generalize
Hopefuly I know what is an url !
|
|
|
|
|
If, as you said, it was an example for others then you shouldn't post a one that is so obviously wrong. Bad examples lead to bad developers following.
|

Hello
Can you tell me what is so that so obviously wrong in my example !!
If you just claim that I didn't give a real url as http://www.microsoft.com
I'm sorry for microsoft
And I apologies for those who don't understand that MyUrl stand for any signifiant url

Right - you use a quoted string there not a variable. That's what is wrong - if you type this in and try to run it, it's not going to understand what you are trying to do. How could it?

Well it is true that "really hard to find" is relative. I always used to hear that there were some people that could not find their way out of a wet paper bag. Now it never seemed to me like that would be to difficult, but then I've never been in one.

Hi All,
Can anyone tell me how set a image on the header of a CrystalReport object programmaticaly?
Thanx
|
|
|
|

I could have sworn CrystalDecisions.CrystalReports.Engine.PictureObject had some properties that allowed you to change the image. Either I'm mistaken or I'm looking at the wrong class.
One way I've done what you're asking for in the past is simply passing the image as a byte array inside a dataset.
First convert:
System.IO.MemoryStream _mystream = new System.IO.MemoryStream();<br />
_mypicture.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);<br />
_mystream.Position = 0;<br />
byte[] _mydata = new byte[stream.Length];<br />
stream.Read(_mydata, 0, (int)stream.Length);
Then add to a data table in your dataset:
_mydataset._mydatatable.Rows[0]["PictureColumn"] = _mydata;
This assumes you're also binding your data through your app. If you're pulling straight from a database, just put the image in a datatable on the database and pull it from there.

Once you add the image column to one of the tables in your dataset, preferably in a table that only has a single row returned. Update the CrystalReport in the designer by refreshing the dataset in the Database expert.
After you do this, you can drag and drop the image into the report as you would any other field.

hii,
Im developing an client server application in C#.
In that i have to use Mobile Agent technology.
On the Server side there is a class...which i want send to the client...by System.IO class..let the class be Mobile...and it has a methode mobilecode()
public class Mobile()
{
public void mobilecode()
{
Code for gathering data from client.
}
}
On the Client side i read this file by stream reader...and i save this class in the same directory of the client.cs project..
on main function of client.cs
i call the class by...
Mobile.mobilecode();
but while compiling..it gives the error...
Mobile doesnt exist...
even if i make an empty class Mobile...thinking it could b overwritten by the code sent from server...dat does not happen...on runtime it reads the same old file...and not the does not updates till the code is executed.
So can anyone help me ou here...as to how to send a class file 4m server to client at runtime and access it immediately at runtime...!!
any help wud b appreciated...
Thnx in advance,,,,!!

creating class is not enough. You should create an object an then use it.
