SystemParametersInfo SPI_SETWORKAREA - C# Discussion Boards

I have a web application which i installed it on a computer, now i had some changes in the application and want to add a version number to the MSI file. Hou can I do that? IS there anything provided in microsoft documentation?

thanks
robust

The app version number is stored in the app.config file, I believe. But when I build an MSI, I put the version number in the title.

Hi there,

I am new in C#,
I am writing a C# application , I need it to be a program that must be installed after that it should start running ones the windows starts up, even before login .

what are the steps can I make so my application be installed by the user
and then how can I make it run before log on windows

Thanks

There is always something to learn

To run before login, the application must be a Windows Service. That's one of the project types in Visual Studio so your first step is to create your app as a service. You then need to add a service installer so that it can be installed in the service manager.

Deja View - the feeling that you've seen this post before.

Thank you,

but I am not very familiar with the windows services ,
so would mind sending me resources that I can learn how to build a service

and how to deal with the service installer

hi again,
thank you very much for the help,
after building my service before the login to the windows , I want to make sure that the service really works , and I was wondering if there is a way to make the service to perform the login to a specific user account ,

if there is such a way, would please send me back

or guide me where to find kind of tutorials about the windows(operating System) functions and what possible things I can let may C# windows service do.

thanks

Is anyone able to help me get this to work? Im not that familiar with the Windows API and have been fiddling around with this for days D'Oh! | :doh:

------------------------

I'm writing a small application at work (programming isn't my primary job function at the moment). I'm using Access to keep track of some information...it's mostly static. At the moment the application and the access database reside on a network share because a few people in my department need to access it. However, I'm using ReportViewer in Visual Studio 2008 and the ReportViewer dlls aren't installed on any of our office machines. If I stick the dlls on the network share they're aren't recognized. I don't have administrative rights to install them on each machine. My thoughts are to zip on up the application and put it on each machine with the dlls files included.

However, the access database needs to remain on the network share so that each user only accesses the one copy of the database. I'm planning on leaving the company in a couple months and no one in my department knows C#. If the network share's URI changes in the future, the application will break. Are they any suggestions for a way to have users be able to change the URI within the application and if it use that URI in the future if for some reason it changed? I want to make it as easy as possible for some of the folks here. I'd rather not have to come back and fix the application in the future just because they decide they need to restructure every year.

Hi everyone,
I am developing for my company a project management system using C# / .NET and MVP pattern. Now I encouter the following design problem:

- I have a project selector GUI containing the list of all available projects where the user can choose one or several project(s) like this:

---------
Please choose one or several projects:
Project 1
Project 2
Project 3
....
Project n

[Open button]
----------

- After choosing one or several projects, a tab appears displaying all project names and the project structure in tree form of the currently tabed-active project is displayed. The project tree consists of working packages and workitems while working packages can in turns contain work items or working items itself (composit pattern), something like this

Project 1
---Kick off phase
---Specification analyze
---- Analyze A
-----Analyze B
---Implementation
.....

The user can click on the item in the project tree have the detailed information displayed, e.g. detailed information of the current project when the root node (Project 1 above) is selected or of working package when a working package node is selected and of work item when a work item is selected.

My question is: how to model all that stuffs in MVP pattern. I guess it would make sence to have a MVP triad like ProjectStructureView - ProjectStructurePresenter - ProjectStructureModel. But should I have each MVP triad for each kind of project item in the tree (project, package, workitem) ?
The fact is, all the displayed information for the current project has only to do with project.
So the other question is: what should be stored in for example ProjectStructureModel?

Your answer would be really appreciated!

Regards.

that was a very cynical answer. Probably the question have been answered too many times with different variations. There are many ways to implement mvp , i use MVC now after the Fowlers retirment note
http://www.martinfowler.com/eaaDev/[^]
in ASP.NET the MVP has many uses .

some of my favorites papers are

www.object-arts.com/papers/TwistingTheTriad.PDF[^]

http://c2.com/cgi/wiki?ModelViewPresenter[^]

http://www.wildcrest.com/Potel/Portfolio/mvp.pdf[^]
in Codeproject also has classical articles and CodeGuru.

Project Model must have . the information about project as you imagine and functionality of how to modify it .
Model may also communicate with the database .or ... there are many issues you must find yourself .

Hi led mike and papadimitriou,
thanks for your reply. In fact I've read many available papers, tutorials about MVP patter include some of your suggested ones. My question goes directly to this particular project.
The root of the project structure tree is the project itself. The root has a list of sub items that are either a working package that can in turns has a list of sub items (working package or work item) or a work item (leaf node). In my implementation, composite pattern is used to model this:

class abstract ProjectElement
class Project: ProjectElement
{
List<projectelement> subItems;
}

class Package: Project
{
List<projectelement> subItems;
}

class WorkItem: Project
{

}

inspirated from some articles about Presenter first method by mean of thinking in "When" Smile | :)

, my thoughts are:

- When the user opens a project, he sees the projecture structure => aha MVP triad ProjectStructureView-ProjectStructurePresenter-ProjectStructureModel

- When the user clicks on an item (which can be either project, package or workitem like explained above) an editor dialog is displayed showing the detailed information of the currently selected node (again project, package or workitem). The user can edit / change these information => MVP triad: ProjectElementEditorView-ProjectElementEditorPresenter-ProjectElementEditorModel. I am stuck at this point: the ProjectElementEditor is an abstract concept (abstract class) which can be either project, package or workitem. My question would be:

Does the MVP triad ProjectElementEditorView-ProjectElementEditorPresenter-ProjectElementEditorModel make sence? Then the ProjectElementEditorPresenter would has an generic interface to a ProjectElementEditorView (which can be either Project general information editor, package information editor or workitem information editor) or should I define for each type of view a MVP triad like:

ProjectGeneralInfoEditorView - ProjectGeneralInfoEditorPresenter-ProjectGeneralInfoEditorModel
PackageInfoEditorView - PackageEditorPresenter-PackageEditorModel
WorkItemEditorView - WorkItemEditorPresenter-WorkItemEditorModel

Hope it makes the problem clearer Smile | :)

dialogs are from Windows 3.0 User Interfaces. Today you can do things like have a splitter so you can present your navigation in one splitter pane and a different view, say for editing, in the other.

Also for .NET applications the PropertyGrid works brilliantly for an editor mechanism

The Properties of the item are displayed in the PropertyGrid

Hello

I've a DataGridView populated with a query

The user can add some rows
The primary key is auto increment and not visible

But some oter fiels can not be duplicated
What is the best way to check them befor to do the update

do I have to make a query in the db for each of those fields before to validate the user entry ?

Any suggestion is welcome

baranils wrote:

Do you mean you created a unique index on the field in MySql?

led mike

Hello !

Not yet

The table contain one auto-increment primary key and a few fields

2 of those fields can't be duplicated because they are alternate identifier for the entity

For now I didn't aplly any index on those fields but I'm looking for the best way to manage them, using MySql ADO and C#

Thank you for your reply !

Well I'm no database expert but it's possible that creating unique indexes in the database is the best practice approach or at least the first step.

led mike

You have to specify IN THE DATABASE that a given column must be unique.

If your database already contains data, make sure that none of the data in that column is a duplicate BEFORE setting the column to be unique.

Hi all,

Can you please assist me with any relevant code in Csharp/ASp.net that helps me reading a CSV file off an Ftp site and populate a table in my database.

Thank you very much.

Check out ye olde FtpWebRequest class, its like HttpWebRequest, but for FTP instead. What you end up with is a stream to the file, then you can read it like you would any other stream.

Can you please give me a little more tips please?

Thank you.

<br />
....<br />
    <br />
    void someButton_onClick(...)<br />
    {<br />
       _mySourceDataRow.Field1 = "New text";<br />
  /*<br />
  What i should write here for ctlTextEdit control reflect changes (i.e "New text")<br />
  But without direct invokation of his methods <br />
  (for examp:this.codeTextEdit.DataBindings[0].ReadValue();<br />
  */<br />
    }      <br />
     <br />

Or exists an method in Form class what make all child controls reread values from ones data sources?

THANK.
