I have a windows servcie application which has apart from OnStart,OnStop() only one more event and is FSWatcher_Created, where FSWatcher is FileSystemWatcher.In FSWatcher_Created eventhandler I have following code:
FileInfo file;
pathToWatch = ConfigurationSettings.AppSettings["PATHTOWATCH"];
//gets file name
fileName = Util.GetFileNameFromPath(e.Name);
//gets file path
filePath = pathToWatch+Util.GetFileNameFromPath(e.Name);
file = new FileInfo(e.FullPath);
MoveTo = ConfigurationSettings.AppSettings["PATHTOFILEMOVE"];
pathToMove = MoveTo+fileName;
if(file.Exists)
{
lock (m_SynLock)
{
file.MoveTo(pathToMove);
}
}
After installing I tested the service. When I drop a file in a designated folder(PATHTOWATCH) it immediately picks up and drops into another folder(pathToMove). If I now do the same second or third time with new file it does not move file to another folder.It seems that windows service somehow does not respond. Can anyone please explain this behaviour and tell me what should I do that it detects the new file and move to another folde?.
Thank you in advance.

Wrap a try catch around your code and see if there exceptions. Also debug it in an exe project first until it works.

C# doesn't allow global variables. Every field is contained in a class. If you need global-like access, you can stick a static field in a static class:
public static class MyStuff
{
public static int MyVar = 15;
}
int val = MyStuff.MyVar;
To be honest though, if you're needing lots of globals, you probably have flawed design. I find static classes to be a rare need; you only truely need them for functions that have zero reliance on other classes, zero dependencies, and each function is completely self-contained with no side effects.

A variable in a report's formula? Sure, so long as you can put the values into the formula from code, there's nothing stopping you from using a variable as input.
But I don't see how this relates to global variables.

You can use it anywhere you like.

Using a global variable is not a good idea.
I think that it's better to use parameter objects rather than global variables.
For example if you have to pass x,y and z to a formula calculator you can have a object that gets x,y and z as parameters and then you can pass this object to a suitable metohd of your calculator.
In form1
<br />
public FormulaParams GetFormulaParameters()<br />
{<br />
FormulaParams params=new FormulaParams();<br />
params.x=int.Parse(this.txtX.Text);<br />
params.y=int.Parse(this.txtY.Text);<br />
params.z=int.Parse(this.txtZ.Text);<br />
return params;<br />
}<br />
In form2
<br />
public void Calculate()<br />
{<br />
Form1 form1=new Form1();<br />
form1.ShowDialog();<br />
int result=new Formula().Calculate(form1.GetFormulaParameters());<br />
}<br />

Hi
plz , read this :
public bool Chk1;
...
private void btnShowName_Click(object sender, EventArgs e)
{
if(CheckBox1.Checked)
Chk1=true;
sqlconn.Open();
da = new SqlDataAdapter(strQuery, sqlconn);
SqlCommandBuilder scb = new SqlCommandBuilder(da);
da.Fill(DS.MyTable);
crystalReport11.SetDataSource(DS);
ParameterField paramfield = new ParameterField();
ParameterFields paramfields = new ParameterFields();
ParameterDiscreteValue discreteval = new ParameterDiscreteValue();
paramfield.Name = "fieldName";
<big>discreteval.Value = Chk1 </big>;
paramfield.CurrentValues.Add(discreteval);
paramfields.Add(paramfield);
crystalReportViewer1.ParameterFieldInfo = paramfields;
crystalReportViewer1.ReportSource = crystalReport11;
sqlconn.Close();}
and Crystal Report , I create a parameter named :"fieldName" , and in Formula Editor , I wrote this :
Global booleanVar Chk1;<br />
if Chk1=true then {MyTable.FirstName}={?fieldName}
finally When I run the App. ,and I checked the CheckBox1, I have no report .
(I want if I checked the CheckBox1 , all record of FirstName field is Shown)
Where is My Wrong ???????
thanx a lot ,
Regards

Well I'm not working with CR anymore
Global booleanVar Chk1;
I can't see where your Chk1 value(the one in formula editor) is assigned.
You create a ParameterDiscreteValue
ParameterDiscreteValue discreteval = new ParameterDiscreteValue();
and pass Chk1 value to it
discreteval.Value = Chk1 ;
but how can you tell the CR that this value should be assigned to your global variable?
It seems that something is missing.
I think that may be you should define a paramter named Chk1 and set its value.

surely , discreteval.Value = Chk1 is a value from Form1.cs .
if not , it doesn't work.

I have a TabControl that is reordering the tabPages when I run the application. There are 10 tabs right now. In the designer, they are in the order I wish them to be. But, when I run the application, they change around a bit. I have tried adding a new tab, then remove it. Still broken. Weird.
Any ideas?

Hi All.
I want do make a vstd2005 setup (windows application) that will contain in itself (embedded) all pre requisites.
What option I need to choose in the prerequisites window of the setup project?
Is the "Download prerequisites from the same location as my application"?
Thx in advance.
Best regards,
Marco Alves.

YOu'll need whatever your app requires. If it's a C# app, you'll need the .NET framework at least, so you'll check that as a prereq (done automatically, IIRC). If your app uses any 3rd party ActiveX controls, you'll need to distribute that. If your app requires any dlls to be installed into the GAC, you'll need to do that as well as part of the install. And so on.

That means you're putting all the prereqs (i.e. .NET framework, etc.) on your website, instead of the vendor's website (i.e. Microsoft, etc.).

Hi Judah, thx a lot.
But, if I choose this option the pre requisites will be placed into my setup "cab" file?
thx a lot.

Ehhh I don't think so. I don't recall very well though, you'd have to try it out.

I thought the deployment project does that for you by checking the dependencies, doesn't it?

I also thought that "Same location as my application" means the same folder. What website you mean?

Eh, sometimes. It can find ActiveX control dependencies, but it can't always do a proper install. Often times you'll need your installer to have the ActiveX control installer run as part of it.

Yeah, that's what I meant: either the vendor's website, or your deploy location.

Hi guys,
How do I change a double value from negative to positive. i.e. -3.14 to 3.14
Please help
sasa
|
|
|
|
|
|
double negativeDouble = 0 - positiveDouble;
|
|
|
|
|
Just for the sake of completeness...
double positiveValue = (double)Math.Abs( negativeValue );
