Hi,
I am using VS2008 and I am trying to access the appSetting value inside the app.config file.
This GetSetting method returns null but there is value in the app.config file?
Any thoughts please?
This is what I am doing:
string logFilePath = Util.GetSetting("LOGFILENAME");
public static string GetSetting(string val)
{
try
{
return ConfigurationSettings.AppSettings[val];
}
catch (Exception ex)
{
return "";
}
finally
{
}
}
--------------
App.Config file contains:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="LOGFILENAME" value="C:\Work\Developments\Services\LogFile\Log.txt" />
<add key="ERRORLOGFILENAME" value="C:\Work\Developments\Services\ErrorLogFile\Log.txt" />
<add key="PATHTOWATCH" value="C:\Work\Developments\" />
</appSettings>
</configuration>

I use VS 2005 and this works:
Properties.Settings.Default["name"]
|
|
|
|
|
I am using a windows service which has the app.config in it.
That does not work.
|
|
|
|
|
In VS2008
Properties.Settings.Default.yourpropertyname
(intellisense should show yourpropertyname)
works, and is (I believe) the currently recommended method.

Maybe this has something to do with this:
[ObsoleteAttribute("This method is obsolete, it has been replaced by System.Configuration!System.Configuration.ConfigurationManager.AppSettings")]
I know that obsolete doesn't mean it doesn't work but try to use the other method.

using Word = Microsoft.Office.Interop.Word;
and some code

{
PowerPoint.Application objApp;
PowerPoint.Presentations objPresSet;
PowerPoint._Presentation objPres;
PowerPoint.Slides objSlides;
public void CreateFile(StringCollection array)
{
String strTemplate;
strTemplate = "C:\\TFSPRESENTATION.ppt";
try
{
//Create a new presentation based on a template.
objApp = new PowerPoint.Application();
objPresSet = objApp.Presentations;
objApp.Visible = MsoTriState.msoTrue;
objPres = objPresSet.Open(strTemplate,MsoTriState.msoFalse , MsoTriState.msoTrue, MsoTriState.msoTrue);
objSlides = objPres.Slides;
// word doc
object oMissing = System.Reflection.Missing.Value;
Word._Application oWord;
Word._Document oDoc;
oWord = new Word.Application();
oWord.Visible = true;
oDoc = oWord.Documents.Add(ref oMissing, ref oMissing,ref oMissing, ref oMissing);
//oWord.ActiveDocument.InlineShapes.AddPicture();
foreach(PowerPoint._Slide slide in objSlides)
{
foreach(PowerPoint.Shape Slideshape in slide.Shapes)
{
if (Microsoft.Office.Core.MsoTriState.msoTrue == Slideshape.HasTextFrame)
{
if (Microsoft.Office.Core.MsoTriState.msoTrue == Slideshape.TextFrame.HasText)
{
//MessageBox.Show(Slideshape.TextFrame.TextRange.Text);
Word.Paragraph oPara1;
oPara1 = oDoc.Content.Paragraphs.Add(ref oMissing);
oPara1.Range.Text = Slideshape.TextFrame.TextRange.Text;
oPara1.Range.Font.Bold = 1;
oPara1.Format.SpaceAfter = 24; //24 pt spacing after paragraph.
oPara1.Range.InsertParagraphAfter();
}
}
if(Microsoft.Office.Core.MsoShapeType.msoPicture==Slideshape.Type)//for image
{
//Word.Shape oPicture;
// oPicture = (Word.Shape)Slideshape
// I am facing problem here, as i m not able to directly transfer pictures from power point slides to word document pictures.
// I dont want to save images on temprory location to my system hard disk. Can anyone guide me to do the same.
}
}
}
}
catch (Exception exp)
{
MessageBox.Show(exp.Message);
}
}
}
Can any one guide me.
Thanks and Regards

Hey guys

namespace DoubleBufferPanelNameSpace
{
class DoubleBufferPanel : Panel
{
public DoubleBufferPanel()
{
this.SetStyle(ControlStyles.AllPaintingInWmPaint |
ControlStyles.UserPaint |

}
thanx

To have it appear in your projects, you need to put it in a dll, and then import it into your project. For something this trival, a snippet could be a better idea ?

thats not what i mean... i can do that... at the moment it is in my solution as a seperate project, compiles as dll and is referenced on 2nd project in the same solution
what i intend is to it have there and ready for me when i make a new solution without having to add the cs file to the solution and compiling the project for it to show up in the tools window
like if you buy a set of controls from devExpress for instance, their controls are in the toolbox without having to do anything
BTW the code was just an example, i actually want to do this for a wrapper class that gives me access to a multimediaTimer...

If you add it to the toolbox, your project needs not to be present, just the dll (somewhere).

how do i do that?
the idea is to add it once and never have to worry about it again... i duno if yall are getting what im trying to say 
let me put it this way...
let say ive developed a commercial control "ButtonVersionTwo", intended to sell to my "clients" for R2  id have to ship it with an installer... how would you tell the installer program to add "ButtonVersionTwo" to the toolbox? because my "clients" dont want to have to add its dll to every project they do...

Just add the dll to the toolbox, close VS, open it again, look at the toolbox, you will notice it is still there, and will be there till you remove it manually.

I would like to create a method that within the method it will handle the mouse click event and after the user has input 2 points the method will return a value back to the caller.
void Test(){
/* The Drawline method should allow user to click the left mouse button 2 times to accept 2 points,after that the DrawLine method will return a true value;*/
bool isDraw = DrawLine();
}
Anyone know what should I do within the DrawLine() method? All help is appreciated. Thanks.

What has this to do with multi-threading? Anyway, return what value back to the caller? What caller? You need to handle the mouse button down/up events I expect.
Post your code for further assistance.

I am sorry, I am not sure whether its something do to with multithreading or not. You can forget about the "caller" if this terms confuse you (Caller means those who call this DrawLine() method). I just want to know how to make the program to stop at the DrawLine() method and after I have accept 2 points from the mouse down button then will return a true value back from the DrawLine method and after that the program will proceed.
void Test(){
/* The program should wait untill I accept 2 points from the mouse down event after that a true value will return by DrawLine() to "temp" variables */
bool temp= DrawLine();
}
I don't know what should I handle within the DrawLine() method.

The exact way describe is not possible in .NET or most languages for that matter.
To do it (exactly) like you show, your language will need to support continuations (only Ruby and Scheme does that AFAIK).
The solution to your problem is to rethink the problem, and design it so it can be handled by the platform/language.

I am using a third party components and it is written by C# .NET and there is a method that works exactly like what I have described previously I wonder how they did it?

Just handle the mouse click event and have a counter var in your class, increment it each time the click event happens and call the drawline method, in the drawline method check the counter, if it's the amount you want (2 in your case) reset it back to 0 and return true.

I have a question, if you want the program to stop at a method (drawLine() in my case), isn't it there must be a loop inside that method and loop untill the user have click the mouse button 2 times and only stop the loop and return a value?

And somehow you cannot do this in the designer?
