Since I already have a ps1 that does this I just figured I could try to run it from VB but what should seem easy is not quite so easy. I've also tried to make the call directly from VB without any success. ps1 triggers a MOVEit automation API call to start a MOVEit task, this isn't really relevant to the code problem below, but it may help with some other suggestion to trigger the API call. Then the error no longer happens, however this does not explain why it fails for Option 1) but succeeds for Option 2) ServicePointManager.DefaultConnectionLimit = 30 net framework 4.7.2 and belowĮDIT2: I've also observed that if I increase the default connection limit by adding If you comment out 1), and uncomment Option 2), then everything will succeed.Ĭan anybody explain what might be happening here?ĮDIT: This seems to work ok with. In the code block of the linq Select statement, Option 1) will fail as described above. var stream = await () Ĭonsole.WriteLine($"Error downloading image") Ĭonsole.WriteLine("= Failed to download one or more image " + e.Message) Ĭonsole.WriteLine($"Successful downloads: ") var response = await httpclient.GetAsync(imageUrl) Var stream = await httpclient.GetStreamAsync(imageUrl) Var downloadTasks = Enumerable.Range(0, 15) HttpClient httpclient = new HttpClient() GetStreamAsync(url), however I could be talking nonsense.īelow is a code snippet that demonstrates the issue.
My suspicion is that it has something to do with ports not being freed up when invoking. However if I use HttpClient.GetAsync(url), then the entire batch will download without any issue.
If I use HttpClient.GetStreamAsync(url) to download the batch, then it seems like some of the requests will timeout, and eventually error. I've been trying to solve an issue I've encountered when downloading a batch of images in my app. My.(TextBox3.Text, ("\\ANVILSRV\Public\Completed Works Orders\" & txt & ""), True) My.(TextBox2.Text, ("\\ANVILSRV\Public\Completed Works Orders\" & txt & ""), True) My.("\\ANVILSRV\Public\Completed Works Orders\" & txt & "")
MsgBox("Could not create the folder " & txt & " because it already exists.") If My.("\\ANVILSRV\Public\Completed Works Orders\" & txt & "") Then Private Sub Button5_Click(sender As Object, e As EventArgs) Handles Button5.Click This is the error that I am getting when trying to complete the operation, it creates the folder and does not move any files. An unhandled exception of type 'System.IO.IOException' occurred in Īdditional information: Could not complete operation since a directory already exists in this path '\\ANVILSRV\Public\Completed Works Orders\98789'.
I am trying to create this code that will allow me to create a new folder in the directory from what I enter into TextBox1.Text, then open a dialog box and select a PDF which will then put the files path into TextBox2 (the same applies for a separate PDF in TextBox3).
