Problem getting propery values with ProperyInfo - C# Discussion Boards

Re: Click a button from a external/downloaded (unknown) html

There is no simple code to just to call click event, because it doesn't exsist. When HTML parse, uses HTML information to handle that button. Here is examaple:

This is snipset of HTML

<form method="get" action="/info/search.aspx" name="Search" style="margin:0;"> 
<b>Search  </b> 
<input class="small-text" name="artkw" style="width:200px;" /> 
<select class="small-text offblack" style="font-weight:bold;" name="sbo"> 
<option value="kw">Articles / Quick Answers</option> 
<option value="fm" selected="true">Messages</option> 
<option value="s">Jobs</option> 
<option value="ctlk">Product Catalog</option> 
 
</select> 
<input type="submit" class="button small-text" value=" Go! " />  
</form>

Important lines:
1st. Line: Form tag has 2 atributes you need to take into an accound. that is Method and Action.
3rd. Line: Input tag is textbox, that has a name as 'artkw'
4th. Line: Is a combo box with a name 'sbo'. All items inside are used with option tag and inportant atribute is a value.
10th. It is an Input with atribute type="submit", witch is a button with a text " GO! " as specified in value atribute.

With this info you can easly request new page. You do not need to type any info or even show the form.

this is how it is processed

<form method="get" action="/info/search.aspx" name="Search" style="margin:0;"> 
// The Url is: "www.codeproject.com/info/search.aspx"
<b>Search  </b> 
<input class="small-text" name="artkw" style="width:200px;" /> 
// The Url is: "www.codeproject.com/info/search.aspx?artkw=text+to+search"
<select class="small-text offblack" style="font-weight:bold;" name="sbo"> 
<option value="kw">Articles / Quick Answers</option> 
<option value="fm" selected="true">Messages</option> 
<option value="s">Jobs</option> 
<option value="ctlk">Product Catalog</option> 

</select> 
// The Url is: "www.codeproject.com/info/search.aspx?artkw=text+to+search&?sbo=kw"
<input type="submit" class="button small-text" value=" Go! " />  
// After this line you can easily request new html page.
</form>

The final url is "www.codeproject.com/info/search.aspx?artkw=text+to+search&?sbo=kw". And then it the server prepares next page based on variables sent.

ps: If you download page to your computer, next page is still depended on server, unless you are attempting to create a local server, where the requested page should be generated

Prevent Visual Studio opening the designer on custom controls

Afternoon. Can anyone remind me of the custom attribute you can apply to a type which prevents Visual Studio from attempting to open the file in a designer rather than code view? I can *never* remember it, and Google's not helping.

Regards,
Rob Philpott.

Hi Rob,

I've hidden it in here[^].

I have a similar question: is there anything one can do to prevent custom controls that are part of the solution, to show up in the Toolbox?

Smile | :)

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that.

Thanks Luc. I have a feeling it was you who informed me of that attribute's presence in the first place!

You want to prevent things being automatically added to the toolbox? Most people like it the other way round. Only suggestion is try using Visual Studio 2003! Actually, I doubt it can be done.

@Luc

I was facing a similar problem. Thus, I chose to disable loading of such controls in toolbar from AutoToolboxPopulate.

Then I added a toolbar button on menubar for "Refresh Project Toolbox Items".

Now, toolbar is not populated automatically. If I need any components in the toolbox, I simply select that project and click on the toolbar button. All compiled components are added to toolbar.

I so rarely want the Designer that I simply set the code editor as the default for forms and controls. I have to right-click to open the Designer. Big Grin | :-D

Problem getting propery values with ProperyInfo

Mark F.1-Mar-10 4:12

1-Mar-10 4:12

I have a custom class TableProperties which has properties for CSS table styles. I have a CustomColor property that has a UITypeEditor to display the ColorDialog control and then convert the color value to a hex string (e.g., ffffff). When I iterate through the PropertyInfo collection the GetValue method returns the property type rather than the value.

// Loop which displays the properties in a ListView control (Testing only).
foreach (PropertyInfo pi in tableProperties.GetType().GetProperties())
{
    name = pi.Name;
    ListViewItem lvi = listView1.Items.Add(name);
    theType = pi.PropertyType.ToString();
    lvi.SubItems.Add(theType);

    // this returns 'TblPropTest.CustomColor' rather than 'ffffff'
    value = pi.GetValue(tableProperties, null).ToString();

    lvi.SubItems.Add(value);
}

The PropertyGrid works fine with the custom properties.

Thanks,
Mark

There are a few ways to fix this. The poblem lies here:

pi.GetValue(tableProperties, null).ToString();

The ToString() method, unless overloaded will return the type. If you can modify the TblPropTest.CustomColor code, you should overload this method. The code below adds an extension method to the Color class to output the Hex RGB value:

public static class ColorExtensions
{
    static string GetHex(byte value)
    {
        return value.ToString("X");
    }

    public static string ToRGBHexString(this System.Drawing.Color color)
    {
        return GetHex(color.R) + GetHex(color.G) + GetHex(color.B);
    }
}

This should be of help. If you cannot use this, please post the code for the TblPropTest.CustomColor type, as this is the root of the problem.

Yes I have overloaded the ToString method. Below are the methods in my CustomColor class. My ToString method was incorrect!

 // This method is incorrect and ...,
 public new string ToString()
 {
     return string.Format("{0:X2}{1:X2}{2:X2}", _Red, _Green, _Blue);
 }

// Should be...
 public override string ToString()
 {
     return string.Format("{0:X2}{1:X2}{2:X2}", _Red, _Green, _Blue);
 }

Thanks for the help!

Resource Manager with GUI for each application

Autodidax861-Mar-10 4:07

1-Mar-10 4:07

Hello together,

i actually have big problems to describe the project I want to realize.

First of all:
I do not ask for any finished solutions, but just for some advice.

We have a resource management tool for managing the ressources of our applications (a ton of win- and web-applications)
in a database.

It works very well for years now, but we often have the (I think common) problem, that our translators translate
the resources without the application context, which leads to the fact, that often a resource does not fit into
the button/label in the application.

Of course, we trim the resources to fit into the according control, but that is not a satisfying solution.
You could also say, that our translators should open the applications and have a look, where each resource will be
displayed, but due to the fact, that we have many applications, none of them is really doing it Wink | ;)

(because they would have to install every application).

That is why I thought about a form, where they could enter the translations "into" the form of the application.

Each developer could prepare "his" form and would provide a library, that would be included into the resource
management tool.

There, the translators have the ability to open the form, and enter the translation "right into the controls".

Once again, this is no request like 'please code that for me', I am looking just for suggestions (maybe a tool like this
exists? I did not found sth. on codeproject. Or maybe there is some code, to load forms from other dll's).

kind regards

Need help getting started with a broadcasting tool

Hi,

I'm quite new to the whole .NET/C# thingy (reading some books now) and I was thinking of something useful to build @ the office.

This is - basically - what I've got in mind:
We have a server on which we build our application. On the server, there should be an application running which accepts commands. The commands can be sent from an application every workstation has to run. If someone sends a command (like: start new build) this single person has to be notified if it was possible to start the command (perhaps there was a build already running?). If the command is executed, the app on the server has to broadcast a message to everybody who has the app running so they know a new build was started.
At the moment all programmers log in to the server (via remote desktop) and double clicks an icon on the desktop. We - obviously - want to limit the access so programmers don't need to log in on the server.

I am thinking of concepts like TCP/IP and/or WCF. Who can help me on my way? Where to start?

Thanks in advance for any information given!

Regards,
Ted

I am building a CAB file for a C# program under VS2005 which includes all of the dependent DLLs, but when I install it under Wince 5.0 it fails to run, claiming missing components. Any suggestions as to why this doesn't work?

TIA! Smile | :)

you might be missing some.

Example: when an EXE depends on A.DLL, and A.DLL depends on B.DLL, and B.DLL is missing, an error will appear as if A.DLL is missing (since it fails to load what it needs).

It's not the job of C# to do so. It's the job of the Setup Wizard. But, it does NOT look at .DLL's to find child dependancies of those .DLL's and children of those and so on and so on. There's no way to tell when it should stop. So, it'll only copy in the .DLL's that your project is dependant on. It will not look for what those .DLL's are dependant on.

I assume you've built on a standard Windows box. It sounds like you have a reference to a component in there that doesn't exist on WinCE 5.

There is nothing wrong with your snipset. I get this in file: 'X-Mms-Message-Type: m-send-req'

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
