[code]It is for ASP.NET, i want to run it in Windows Application. I get an error says FileUpload reference doesn't exist or so. FileUpload resides in System.Web.UI.WebControls which doesn't belong to Winforms family.Please note that the file will be saved from desktop to remote file server (not ~/Uploads).
View 2 RepliesI have a User Control that contains a System.Web.UI.WebControls.FileUpload control as well as a button to 'Submit'.
When the button is clicked code similar to the following is executed:
If FileUploadControl.HasFile Then
'Save the file and do some other stuff
End If
This code works just fine with Windows XP. However, if I run it from a Windows 7 64-bit machine using IE8 32-bit the HasFile property always returns false and nothing is saved?!
I have a VB 6 SP6 application that uses DirectX 7 to interface to a USB joystick (Logitech Extreme 3D Pro).The application works under Windows XP Pro (32-bit).I've got Visual Studio and the application running under Windows 7 Pro SP1 (32-bit).
I've calibrated the joystick under Windows 7.The VB 6 application does not find any DirectX 7 joystick device to connect to.Otherwise, the VB 6 application works (GUI, embedded video, serial channel, Ethernet connections).The VB 6 application must be accessing the dx7vb.dll or it would crash.The joystick disc did not provide a driver.I installed the latest joystick Profiler vendor software from the Web.This is my first attempt to use Windows 7 as a platform.I'm not sure what to try from a Windows 7 perspective.

frmOdyssey is the main form, from which frmSearch is called. After the above processing, I want to go BACK to frmOdyssey to process the FilFilterGrid sub on the Grid defined on frm Odyssey. I will be assigning a new DataSource for the Grid, which will be "selected down" by the strFilter. The above code works with no issue whatsoever in "Windows Application" mode. However, if I switch to "Class Library" mode, I get
an error on the last line of the last Sub, telling me "Reference to a non-shared member requires an object reference". If I uncomment the "Dim f As New frmOdyssey" line, and change the "frmOdyssey" to "f" on the next line, the error goes away, but then the process doesn't work, because the "select down" does not happen. I don't know why, except that "logically" I don't want a "new version" of the frmOdyssey. I want to update the existing form.

I have a class library in VB.NET that does a NET-envelope for an USB device driver.There is only one function of that driver that I could not envelope in a traditional class, but I had to put it in a Windows Service as described here:Sharing a class property (field) between applications.The Windows Service works fine, but I have now two projects for my NET-envelope: the one with the class library, the second with the windows service and I do not like the idea to maintain two distinct projects for the same driver.Is it a good practice (or even if possible) to add a windows service class to a normal class library (without creating its own project as described in the vb tutorial)?I know, in any case I should create a separate setup only for the windows service, but in this way I could have together all the classes that envelope my usb device driver in only one project.

View 8 RepliesI'm writing an intranet ASP.NET page using VB.NET. I've run into a particularly nasty problem dealing with handling file uploads. I'll do my best to explain the problem, and perhaps someone can help.
My problem is almost a duplicate of this one, or this one, except (other than the filename) I don't care about sending the file to the server until the other data has been reviewed. here's the situation:
Joe Q. Dataentry inputs some data into several fields. The first 3 are drop down, and when he changes the selection, a postback event is fired that queries a database for valid entries for the other drop down selections. After selecting the values, he inputs some other data, chooses a file to accompany the data and clicks the "Update" button. When he hits the button, it fires a postback event that sends the current data to the server to be validated. The data will create a change in the database, so he is presented with a view of the current state, and what it will look like when his changes are made. He can now either confirm or cancel the operation for whatever reason.
Part of the data he will see involves the extension of the file which may be a PDF, or could also be some image file or other document.
Now here's where my problem is - on each postback event, the fileupload dialog is cleared. I was getting around it by creating a temporary file on the first postback and then renaming if he clicks OK or deleting on Cancel... but I need to do a variety of things, based on the previous state of data and the filename. I've tried to keep some session variables to retain the filename, and that works OK for just renaming the file, but for what I need to do it gets unwieldy.
What I want to do is be able to have the postback event to present the changes, and then when the user clicks "OK", submit the file. Is there any possible way to do that?
One of my thoughts was to do some of the validation client-side (I'm already re-validating server side so I'm not too worried about data security there), but I don't know how I could get the information from the database query. It appears that what I want to do is prevent a certain button from firing a full postback. Is there any way to do that?I have an update panel on the page already - is there any way for the button to only post what's in the update panel?
I have a problem with FileUpload, when I select a file from the local machine, it will not bring the real path of the file, it will use the path for the project files and assume the file I am selecting is there, any ideas?
Example:File name is "Q.JPG" and is in "C:" when I browse to "C:" and select "Q.JPG" and click open, I get the following Error Could not find file 'C:Program FilesMicrosoft Visual Studio 8Common7IDEq.jpg'.So when I fire up the code for Uploading the file to FTP for example, it will return an error because file doesn't exist

I guess this is a reference issue, but I have added references to WMP libraries (axinterop.wmplib.dll and interop.wmplib.dll). The WMP works on the XP machine, but not when called from my application.I have searched the web now for 5 days and changed references, and reinstalled the media player on the XP machine, but nothing works.
