Application inexplicably failing capturing screenshots

I have an odd issue that I have been trying to pin down for awhile. Essentially my application opens up various URL's using chrome (data from an array), takes a picture of them, saves them, and continues on looping through the array. The application successfully launches and runs, but variably it fails (usually between 2-5 days). When it fails, chrome no longer appears to open but the application continues to 'run'. Here is the error that is being produced from my try/catches:
at System.Drawing.Graphics.CopyFromScreen(Int32 sourceX, Int32 sourceY, Int32 destinationX, Int32 destinationY, Size blockRegionSize, CopyPixelOperation copyPixelOperation)
at Command_Center_Screen_Capture_Agent.Form1.Capture(String name)
My only working theory right now is that there might be an issue with the memory since it's failing to take the picture and failing to open the browser, but I'm not sure how to test that theory.
{UPDATE} Going through the logs on all of my servers, I noticed that while only some had the error above, all of them had the following error:
at System.Drawing.Image.Save(String filename, ImageCodecInfo encoder, EncoderParameters encoderParams)
at System.Drawing.Image.Save(String filename, ImageFormat format)
at Command_Center_Screen_Capture_Agent.Form1.Capture(String name) in SERVER REDACTED\Visual Studio 2012\Projects\Command Center Screen Capture Agent\Command Center Screen Capture Agent\Form1.cs:line 170
This error appears to always be the last error before the system stopped logging and (theoretically) failed.
The code in question is:
try
{
GFX.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
Screen.PrimaryScreen.Bounds.Y,
0,
0,
Screen.PrimaryScreen.Bounds.Size,
CopyPixelOperation.SourceCopy);
}
catch (Exception e)
{
//Noticed without this if the program was running before skyvision was opened an occasional error popped up
error_logging(e.StackTrace);
}
// Save the screenshot to the specified path
try
{
String filePath = #"\" + pictureNames[count] + ".png";
// MessageBox.Show("Saving file to: " + FILEPATH_LOCATION + forTesting);
BIT.Save(#FILEPATH_LOCATION + #filePath, ImageFormat.Png);

Upload a file using file upload in ASP.net

I wrote the code to upload the file and save in project root directory. How can I change this to save the path into database and the files into a separate folder from project?
protected void UploadButton_Click(object sender, EventArgs e)
{
if(FileUploadControl.HasFile)
{
try
{
string filename = Path.GetFileName(FileUploadControl.FileName);
FileUploadControl.SaveAs(Server.MapPath("~/") + filename);
StatusLabel.Text = "Upload status: File uploaded!";
}
catch(Exception ex)
{
StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " + ex.Message;
}
}
}

protected void UploadButton_Click(object sender, EventArgs e)
{
if (FileUploadControl.HasFile) {
try {
string filename = Path.GetFileName(FileUploadControl.FileName);
FileUploadControl.SaveAs(Server.MapPath("~/") + filename);
saveImgPathToDB(filename, 3);
StatusLabel.Text = "Upload status: File uploaded!";
} catch (Exception ex) {
StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " + ex.Message;
}
}
}
private void saveImgPathToDB(string path, int recordID)
{
using (sqlconnection db = new sqlconnection("your_connection_string")) {
using (sqlcommand cmd = new sqlcommand("INSERT INTO photo_table (PhotoPath) VALUES (#path) WHERE someId=#someid", cn)) {
cmd.parameters.addwithvalue("#path", path);
cmd.parameters.addwithvalue("someid", recordID);
cmd.connection.open();
try {
cmd.executenonquery();
}
}
}

How to Transfer Files in different Threads with FileWatcher

I have a form with a File Watcher to which he transfers to multiple addresses all video files placed in a folder. What is the best option so that when multiple files are added to even be able to perform each transfer in a thread. Here's an example of my code:
DockingBarTransferEntities context = new DockingBarTransferEntities();
private void fileSystemWatcher1_Changed(object sender, System.IO.FileSystemEventArgs e)
{
IEnumerable<Diretorios> directories = context.Diretorios.ToList();
foreach (var destino in directories)
{
try
{
Transfere(e.FullPath,Path.GetFileName(e.FullPath),destino);
}
catch (Exception ex)
{
textBox1.Text += "Error: " + ex.Message;
}
}
}
public void Transfere(string fullPath, string name, Diretorios diretorio)
{
try
{
if (Directory.Exists(diretorio.Caminho))
{
string fileName = Path.GetFileName(fullPath);
fileName = String.Format("{0}\\{1}", diretorio.Caminho, fileName);
FileInfo arquivo = new FileInfo(fullPath);
arquivo.CopyTo(fileName, true);
}
}
catch (Exception ex)
{
}
}

It should be as simple as this:
Task.Factory.StartNew(() => Transfere(e.FullPath, Path.GetFileName(e.FullPath), destino));
instead of calling Transfere directly.

error in C# project

here are my two functions:
public void SetCompanies()
//set the Companies table from Shret.net DataBase
{
try
{
WebClient webClient = new WebClient();
Uri uri = new Uri("http://api.sherut.net/?method=Company");
webClient.OpenReadCompleted += new OpenReadCompletedEventHandler(webClient_OpenReadCompleted);
try
{
webClient.OpenReadAsync(uri);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
void webClient_OpenReadCompleted(object sender, OpenWriteCompletedEventArgs e)
{
try
{
DataContractJsonSerializer serializer = null;
var companies = (Companies)serializer.ReadObject(e.Result);
foreach (Company c in companies.data)
{
MessageBox.Show(c.Name + " " + c.CompanyID);
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
}
and this is the error i get:
"No overload for 'webClient_OpenReadCompleted' matches delegate
'System.Net.OpenReadCompletedEventHandler'"
i dont understand why, because i wrote the handler after this function......
Thanks in advance!

OpenReadCompleted doesn't take OpenWriteCompletedEventArgs.
