do
{
iniText = iniStream.ReadLine();
if(String.Compare(iniText.Substring(0,1),("*")) == 0)
continue;
string [] dataItems = iniText.Split(new Char [] {','});
dataGridView1.Rows.Add(dataItems);
} while (iniText != null);
When stepping through the code, dataItems correctly contains each array of comma separated variables, but the datagrid control is not being populated with the Rows.Add method. What am I missing?

OK, I changed it to this
do
{
iniText = iniStream.ReadLine();
if (iniText == null)
continue;
if(String.Compare(iniText.Substring(0,1),("*")) == 0)
continue;
string [] dataItems = iniText.Split(new Char [] {','});
dataGridView1.Rows.Add(dataItems);
} while (iniText != null);
obviously I need to rethink my loop logic. But when i step through in Debug with F5 it populates the control properly, when I run without debugging, it is still empty. Why does that happen?

I agree your loop logic needs some work, but in both original form and the modified form below it works fine either debugged or run as release version.
Without seeing the rest of your code, I can only assume the difference is path related - is the file you are reading relative to the debug code folder and thus not available in the release version?
string[] lines = File.ReadAllLines(@"C:\XXTemp\new.txt");
foreach (string line in lines)
{
if (!line.StartsWith("*"))
{
dataGridView1.Rows.Add(line.Split(','));
}
}

Thanks. Of course, that is exactly what it was, I hadn't changed the file read section to allow the user to browse for an actual file location!
doh! thanks for the heads up

Hi,
I want to write some data to an excel sheet. If it is open, then write to the same excel sheet, if not open, then open the excel sheet and perform operations.
I dont know how to get control of the open excel sheet.
Here is my code:
//check if the worksheet is already open.
try
{
using (FileStream fs = File.Open(txtBx_worksheetPath.Text, FileMode.Open))
{
if(fs == null)
{
theWorkbook = ExcelObj.Workbooks.Open(txtBx_worksheetPath.Text, 0, false, 5,
System.Reflection.Missing.Value, System.Reflection.Missing.Value, false, Excel.XlPlatform.xlWindows,"\t", true, false, 0, true, false, System.Reflection.Missing.Value);
}
}
}
catch(Exception)
{
// activate excel sheet
// theWorkbook.Activate();
}
Now, if the file is already open, then it performs nothing.
I dont want to close the excel sheet and reopen it.
Please help me.
Thanks
Ananya

I am working with World of Warcraft and C#. In WOW there is no way to send data out to another app nor are you allowed to use Spy++ to read data from WOW. A though occurred to me to simply create an Addon that draws a series of colored boxes near the top of the screen away from any that would get in the way of the users use of WOW. These colored boxes would represent a value I would read in via C# screen area capture. My question is, is this the best way to go about something like this or is there a better way?

I read an article here on CodeProject that used 3 programs to have Source Control in Visual Studio.
VisualSVN Server
TortoiseSVN
AnkhSVN
They all seem to do the job, and they all seem to do so fairly easily. I am wanting to use this just so I can host my personal project code on a server and not have to carry the code on a flash drive anymore (it is very unsettling to do so).
My question is has anymore used these before and can give a good review on them, OR does anyone have an idea of one that might fit a little better for my needs? I am just trying to store all my code(i.e. personal use) on a server with simple versioning, and access to the code from multiple laptops/desktops ect.
Thanks for any and all help, and I am positive that this is in the wrong forum, not sure where it goes, I used to post these kinds of questions in the Lounge, but it says no programming questions, and I don't want to put this in one of the more-or-less dead forums.

I got anxious and continued to do research while I waited for an answer. The only one I kept seeing over and over was VisualSVN, so I setup the server, installed the client, and it made me download TortoiseSVN. I don't need the 3rd one.
I have been playing around with it using my desktop, and laptop, and so far, I am loving it.

Hello everybody,
I have a problem to which I haven't been able to find an answer through Google. I am making a windows service that reads image files in an input folder and then profiles the document in a document management system. The program can't manipulate images itself so it's OCR and Barcode reading, and image splitting, converting and combining functions are performed in separate applications using the System.Diagnostics.Process class.
The problem I am running into is that when I call my TiffSplitter app I get a System.OutOfMemoryException when I the image is first loaded into the program. In initial testing I found that I could set the "Allow service to interact with desktop" property of the service and it would run on my development PC but this quick fix didn't solve the problem on a client site.
I know that setting that property isn't a proper solution either so I'm open to ideas as to how to properly fix this. The reason this program is a service is so that it will auto start on system startup and doesn't require a windows user to log on to windows to start working. Is there any way of increasing the amount of memory that a process can use? Or is there some other solution that I'm missing?
Here some info about The PC's and the Program:
Development PC-
OS: WIN XP with SP2
Pentium 4 2.80GHz
2GB Ram
Client Server-
OS: WIN Server 2003
Runs on a virtual machine
TiffSplitter app-
vb6 app
Uses Imaging Pro to split and OCR Tiffs
Program loads fine but errors out on the image loading functions
Service app-
C# 2.0 app
Uses following code [Paraphrased] to open TiffSpliter:
using (Process p = new Process())
{
p.StartInfo.CreateNoWindow = true;
p.StartInfo.UseShellExecute = false;
p.StartInfo.Arguments = [args];
p.StartInfo.FileName = [exe];
p.Start();
p.WaitForExit();
p.Close();
}

Hi,
Fallout_Monkey wrote: I get a System.OutOfMemoryException
When we loop through some thing with out an End, we usually get this error.
So please check all your methods, or just create a log files for each method,
and identify is there any loop goes on.
Because your tiny program will have the sufficient memory untill some thing goes wrong.
(i have not given the solution, just its my observation on your post)

Thank you for your reply.
There is no infinite loop as your proposing. I know this because the exact same code will run on in a console app on the desktop with the same input. Also the line of code that throws the error is not in a loop.

If you're processing TIFF files, make sure your VB6 app isn't trying to display the image. GDI and GDI+ do not support JPEG compressed TIFF images, so this could be the cause of your problem. I'm not familiar with the library you're using so I cannot comment on the reliability of it.
|
|
|
|
|
Thank you for your reply.
The fact that it is a tiff has no bearing on this situation because I am not using GDI. I am using a third party control that is rendering and OCRing the image.
|
|
|
|
|
...and if that third-party control is using GDI...??
|
|
|
|
|
As you said GDI doesn't handle tiff images and this this control does so it is probably safe to say that it uses some other proprietary library to do this. Regardless, the fact remains that this error occurs on my development box only when I run it as a service without access to the desktop. When I run it as a console app or give it access to the desktop it runs fine. Also the service does call another app to combine tiffs. This second app uses a library written in .net 2.0 and itself uses GDI+ and the app runs fine in all the situations I have mentioned whereas the vb6 app doesn't when it is run from a service(with or without desktop access on the client server).

No, I said GDI/GDI+ can't handle JPEG (LZW) compressed TIFFs. Uncompressed and other format TIFFs are not a problem.
If it works on one machine and not another, I'd start by following the references using Dependency Walker and make sure all references resolve on the machine it breaks on.

Forget different machines for a second. I don't know why it works on the same machine(the client server) from a console app but gets the out of memory exception when running from a service and the error is occurring in a separate app which doesn't change between the two versions of the parent app. I don't think it's a dependency issue. I mean if I was calling a vbscript with everything the same and the script ran from the console app but not from the service, would you be saying the check the dependencies?
|
|
|
|
|
Well, there's a bunch that changes between a console app, a service, and a normal Windows app. Apartment models, message pumps, execution environment, ... The dependancies DO change depending on if the app is a console or a Windows forms app.
If you really want to get to it, I'd probably contact whoever wrote the controls/classes your app is using and see if those controls/classes have been tested in Console and Service apps and if they have threading apartment model restrictions.
Any "normal" code doesn't really change between the different app types, but the framework around your app does and so do the requirements of third party components.
Fallout_Monkey wrote: I mean if I was calling a vbscript with everything the same and the script ran from the console app but not from the service, would you be saying the check the dependencies?
Not exactly a good example since the script runs in a completely seperate (and consistent) execution environment.

I apologize I'm an idiot. I didn't read my logs correctly and have found that the out memory error occurs on the desktop app as well. But it is sporadically. It will process a whole bunch and start getting the error for the next bunch of images. And I can rerun some of the ones that fail and they work. Could it be that the VB6 app is just not cleaning up properly when I shut it down?
|
|
|
|
|
The VB6 runtime cannot clean up what it did not allocate. If you've got a leaky library that the app is using, then yeah, you can run into a problem like this.
