Why don't you just quit the excel instance through your code?
|
|
|
|
|
I tried Quit() along with setting it to null but the process still existed. Any other idea?
I am thinking of logging the time my app starts and then checking the start time of each process. If the start time is bigger than start time of app and created by the same user then I will kill it. But it is still possible, the user opened an excel file outside my app while my app is active so this is not the best solution.

Did you try something along the lines of
Where _excelApplication = Excel.Application
_excelApplication.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject(_excelApplication);
?
|
|
|
|
|
Just did both quit and ReleaseComObject methods but still there.

Hope you can follow it through since I have written it in VB.NET.
This is just a wrapper. The parts which might be of interest to you are the constructor and the Create method.

next time, post your question in the vb.net forums, it really helps to know what language you are dealing with.
Secondly, use the pre tags.
Thirdly, this is how I did it (in vb.net)
Public Sub Terminate()
If _excelApplication IsNot Nothing Then
_excelApplication.DisplayAlerts = False
_excelApplication.Quit()
System.Runtime.InteropServices.Marshal.ReleaseComObject(_excelApplication)
_excelApplication = Nothing
_excelApplication.Finalize()
End If
End Sub
jeez.

Sorry about that. The reason I posted it here is because I did not think it will get to the point where I need to post code.
Still no luck. The process exists after doing all of the above.

You mean it worked for you? Finalize() is not a member of Excel.Application.

Err....ummm....does the process exist before execution...?

No, I manually check to make sure no process exists before the execution and I also kill all the instances programmatically just to reassure using this code:
foreach (Process p in Process.GetProcessesByName("EXCEL"))
{
p.Kill();
}

Again that is horrible design, what if a client has excel running?
Create a new instance of excel, and set it's IgnoreRemoteRequests property to true, this will cause *your* instance of excel to operate under a new process.
|
|
|
|
|
How do you create excell processes?
System.Diagnostics.Process.Start("...") Something like that? If so save the process that you create.
List<Process> list = new List<Process>();
Process p = System.Diagnostics.Process.Start("...");
list.Add(p);
...
list[i].Kill();

No, the problem is to make excel spreadsheets you have to create a new instance of the application class and add workbooks to it. This creates a process and I am trying to kill the process which I created but no luck so far. Here is the snippet:
public void Constructor(Parameters params)
{
this._xlApp = New Application(); // This is the process I want to kill once I am finished creating the file.
this._workBook = Me._xlApp.Workbooks.Add();
this._repoHelper = null;
this._sheets = New Dictionary<String, Worksheet>(53);
this._parameters = params;
}

Hi,
I'm kind of new to programming and to c# about 18 months c# and twice that with vba with bits of javascrip and, vbscript... and a hobbyist so it sounds a lot but it isn't!
Anyways I have never used images before in programming other than to swap a picture given a value in the code.
I now want to be able to have an image on a windows form that you can left click and a dialogue box appear that shows the position in pixels the mouse is on the image.
To be honest I'd be happy with just that. BUT really on the picture I want to have (probably the wrong word) but 'hotspots'/hot areas.
I am designing a form to be able to record where on a person has an injury. I want the user to be able to click say on the left shoulder of the person on the image and the program know that the user clicked on the left shoulder at the image pixel count of (100, 100) for example.
Would it be best to do this thru a browser displayed image that has a javascript script running on it and embedding in it somehow position (left shoulder) the user has clicked?
The reason why I want need the pixel count is because the results will be shown on a website.
Am I attempting too much? Could somebody please give me some direction?
Thank you in advance,
Mark

Take a look at The Hot Spot .NET Control[^], to see if it gives you any ideas.
A friend of mine did an application for Bronchoscopy using similar techniques in VB 3.0 some time ago.

Since it featured a diagram of the human body, there was some degree of articulation, certainly.

Come to realize VB3.0 probably is more 13ishish, real PCs[^] not being around for 30 years yet.

Yes, it was about 1995-7, and given that it was VB, it was actually quite a nice app.

Hi
Actually I made a visual C# application & want it to Run on LAN with a Centralized database server so that my People can use the database situated at server from their client through a Client C# Application. How Can I do so.
is it simply making the setup file & then deploying into network machines....or is it some thing else...
regards

You don't need to deploy your application on the LAN to use a database on the LAN.

Hi,
I would like log my keyboad strokes in a xml file. The attribute can be the key, and the value can be the timestamps or the other way ( doesn't matter). I would like to write the schema in the way that my output of schema would be exactly like this:
<LoggingActions>
<Keyboad>
<Entry key="a">0</Entry>
<Entry key="b">1213</Entry>
<Entry key="c">3445</Entry>
</Keyboad>
</LoggingActions>
so far, this is my schema:
<xs:element name="MyEvents">
<xs:complexType>
<xs:sequence>
<xs:element ref="LoggingActions"/>
</xs:sequence>
</xs:complexType> </xs:element>
<xs:element name="KeyboardEvent">
<xs:complexType>
<xs:sequence>
<xs:element ref="MyKeyEntry"/>
<xs:element ref="Time"/>
</xs:sequence>
</xs:complexType> </xs:element>
<xs:element name="MyKeyEntry"> <xs:complexType>
<xs:sequence>
<xs:element maxOccurs="unbounded" ref="keyReference"/> </xs:sequence> </xs:complexType> </xs:element>
<xs:element name="Time">
<xs:complexType>
<xs:sequence>
<xs:element maxOccurs="unbounded" ref="timeRef"/>
</xs:sequence>
</xs:complexType> </xs:element>
<xs:element name="keyReference" type="xs:string"/> <xs:element name="timeRef" type="xs:int"/>
Instead, I am getting this xml as my output:
<LoggingActionsxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<LoggedKey>
<MyKeyEntry>a</MyKeyEntry>
<MyKeyEntry>b</MyKeyEntry>
<MyKeyEntry>c</MyKeyEntry>
</LoggedKey>
<Time>
<timeRef>0</timeRef>
<timeRef>1213</timeRef>
<timeRef>3445</timeRef>
</Time>
</LoggingActions>
How can I combine these two together?
thanks,
