    - by DK39
    I'm uploading multiple files using FtpWebRequest. But for every file I'm opening and closing a connection. How can I upload multiple files using the same connection? Like a ftp client application, connect using username and password, change directory, upload file1, upload file2, upload file3, disconnect.

  • get full path of active window's process (vb.net)

    - by Jonathan
    I can get the active window's process, but I have no idea how to get the location of that process, as far as I can see the process object only has ProcessName property which just returns like chrome instead of C:\pathtochrome\chrome.exe How can I get the latter because I'm trying to get the process's File Description attribute, but I need the full path to it.

  • Sizing issues while adding a .Net UserControl to a TabPage

    - by TJ_Fischer
    I have a complex Windows Forms GUI program that has a lot of automated control generation and manipulation. One thing that I need to be able to do is add a custom UserControl to a newly instatiated TabPage. However, when my code does this I get automatic resizing events that cause the formatting to get ugly. Without detailing all of the different Containers that could possibly be involved, the basic issue is this: At a certain point in the code I create a new tab page: TabPage tempTabPage = new TabPage("A New Tab Page"); Then I set it to a certain size that I want it to maintain: tempTabPage.Width = 1008; tempTabPage.Height = 621; Then I add it to a TabControl: tabControl.TabPages.Add(tempTabPage); Then I create a user control that I want to appear in the newly added TabPage: CustomView customView = new CustomView("A new custom control"); Here is where the problem comes in. At this point both the tempTabPage and the customView are the same size with no padding or margin and they are the size I want them to be. I now try to add this new custom UserControl to the tab page like this: tempTabPage.Controls.Add(customView); When making this call the customView and it's children controls get resized to be larger and so parts of the customView are hidden. Can anyone give me any direction on what to look for or what could be causing this kind of issue? Thanks ahead of time.

  • Redundant assert statements in .NET unit test framework

    - by Prabhu
    Isn't it true that every assert statement can be translated to an Assert.IsTrue, since by definition, you are asserting whether something is true or false? Why is it that test frameworks introduce options like AreEquals, IsNotNull, and especially IsFalse? I feel I spend too much time thinking about which Assert to use when I write unit tests.

  • Best way to globally set every control's ValidationGroup property in an asp.net?

    - by Steve Flook
    I have a User Control with form items that is re-used considerably throughout a large web application, and up until this point the validation summary upon an invalid form submission is being handled by the .aspx that consumes the User Control. Now I need to set the ValidationGroup property at runtime for each of my form items controls (textboxes, lists, validators, etc). Rather than do it manually by setting each control I'm interested in iterating through all the controls in the User Control, detecting if that control has a ValidationGroup property, and setting it's value that way. Something like this: For Each ctrl As System.Web.UI.Control In Me.Controls ' so now what is the proper way to detect if this control has the ValidationGroup property Next Code sample in vb.net or c# works for me. Many thanks!

  • ADO.NET: Can't connect to mdf database file

    - by Nabo
    I'm writing an application that uses a SQL Server 2005 database. In the connection string i'm specifying the mdf file like this: connstr = @"Data Source=.\SQLEXPRESS; AttachDbFilename=" + fileLocation + "; Integrated Security=True; User Instance=True"; When i execute the code: public static void forceConnection() { try { conn = new SqlConnection(connstr); conn.Open(); } catch (Exception e) { MessageBox.Show(e.Message, "Erro", MessageBoxButtons.OK, MessageBoxIcon.Error); } finally { if(conn != null) conn.Close(); } } I receive an exception: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) This code works on XP but not in Vista.. I tryed run Visual Studio in admin mode and moved the mdf file to "user data" folders but the error persists.. Any help? Thanks!

  • Combining two .png images into one image using .NET

    - by Omega
    I have two (actually many) .png images in my application. Both have transparent areas here and there. I want, in my application, to take both images, combine them, and display the result in a picture box. Later I want to save the result through a button. So far I managed to find the two images and combine them, but it seems the transparency thing won't work. I mean, if you put one image over another, only the top image is visible as the result because, apparently, the image's background is a plain white box. Which is not. Here is a bit of my code: Dim Result As New Bitmap(96, 128) Dim g As Graphics = Graphics.FromImage(Result) Dim Name As String For Each Name In BasesCheckList.CheckedItems Dim Layer As New Bitmap(resourcesPath & "Bases\" & Name) For x = 0 To Layer.Width - 1 For y = 0 To Layer.Height - 1 Result.SetPixel(x, y, Layer.GetPixel(x, y)) Next Next Layer = Nothing Next resourcesPath is the path to my resources folder. Bases is a folder in it. And Name is the image's name. Thank you.

  • Where is the windows app installed + .NET + VS2005

    - by The King
    I deployed a windows application in the following website http://StagingServer/MyProgs/MPP/ on my intranet site, using the Publish Wizard of VS 2005... I accepted all defaults (including Offline support). My users were also able to install the same from the path specified. But when I try to find out the exact location of the EXE in the client, it is not pointing anywhere. I also tried a file search but in vain. Initially I thought the application is running from the server itself, but we were able to start the app, even when the server is down (ofcourse it takes more time to search for updates initially). Ps : The app is showing even in control panel... Raja

  • Call .NET Webservice with Android

    - by Lasse P
    Hi, I know this question has been asked here before, but I don't think those answers were adequate for my needs. We have a SOAP webservice that is used for an iPhone application, but it is possible that we need an Android specific version or a proxy of the service, so we have the option to go with either SOAP or JSON. I have a few concerns about both methods: SOAP solution: Is it possible to generate java source code from a WSDL file, if so, will it include some kind of proxy class to invoke the webservice and will it work in the Android environment at all? Google has not provided any SOAP library in Android, so i need to use 3rd party, any suggestion? What about the performance/overhead with parsing and transmitting SOAP xml over the wire versus the JSON solution? JSON solution: There is a few classes in the Android sdk that will let me parse JSON, but does it support generic parsing, like if I want the result to be parsed as a complex type? Or would I need to implement that myself? I have read about 2 libraries before here on Stackoverflow, GSON an Jackson. What is the difference performance and usability (from a developers perspective) wise? Do you guys have any experince with either of those libraries? So i guess the big question is, what method to go with? I hope you can help me out. Thanks in advance :-)

  • Confirm box always displays first (javascript, jQuery, .Net)

    - by Jan-Frederik Carl
    Hello, I have a jQuery-Script to accomplish the following tasks: if a gridview in my form contains a row with a certain id, it has to be marked red. a confirm dialogue has to pop up to ask the user if he wants to do this or that. I built this code: if (response == "EntryInList") { $('#entryListContainer div table tbody tr').each(function() { if ($(this).attr('id') == 'entry_' + $('#<%= txtProductNumber.ClientID %>').val()) { $(this).css("color", "red"); } } ); if (!confirm("Entry already exists. Really overwrite?")) { jQuery('#<%= txtProductNumber.ClientID %>').val(''); jQuery('#<%= txtCount.ClientID %>').val(''); jQuery('#<%= txtProductNumber.ClientID %>').focus(); return false; } } As a result, the confirm box pops up first, without the row being turned red. Only after using the box, it becomes red. How would I get the row to be turned red at once? Another of my problems is that the confirm box denies my page to be scrolled down. But I would like to do this if the gridview is longer than the entire page.

  • .NET Web Service Proxy is adding special characters in XML

    - by xkingpin
    My web service proxy seems to be adding special characters like "*" and "#" etc. within the xml nodes. My proxy created lists using arrays of objects. I am trying to create a generic list and then doing list.ToArray() to set the proxy MyProxyObject[] object. Is this the cause of the problem I am having? I plan on running fiddler on the request later but it is over SSL and I do not have access to the URL at the moment. Here is an example of the XML that is generated: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> * <soap:Body> o I'm a little concerned because the special characters are even occuring before the array nodes

  • .NET, ASHX, "Server cannot append header after HTTP headers have been sent" after sending PDF Streem

    - by Inturbidus
    I visit my ASHX file, and it outputs a PDF perfectly. If I visit the very same ASHX with a different query string (I append DateTime.Now.Ticks to the end each visit), and I get this error: Server cannot append hader after HTTP headers have been sent. My code is below: copy.CloseStream = false; document.Close(); var r = context.Response; r.ExpiresAbsolute = DateTime.Now; r.BufferOutput = true; r.ContentType = "application/pdf"; r.AppendHeader("Content-Type", r.ContentType); r.AppendHeader("Content-disposition", "inline; filename=" + context.Server.UrlEncode(formType.File_Name)); r.BinaryWrite(copyStream.ToArray()); r.StatusCode = 200; r.End(); originalReader.Close(); copy.CloseStream = true; copy.Close(); There is no other place in this code that headers are sent. You are seeing the entire interaction with the Response object. I've tried to use r.Flush(); and r.End(); I've also tried not sending them if they are already there, but this causes other issues.

    Does anybody know if you can access the SaevFileDialog control that's used by the WebBrowser control? Once somebody saves the webpage being displayed I need to catch where the files have been created; however I can't seem to find any events/members that allow me access to that information.
