VB 2005 App Failing To Start Pscp Subprocess
Jul 7, 2011I've got a VB2005 application written by a previous coder. I had to move it to a new windows 7 box, since the xp box it was hosted on had catastrophic hard drive failure. It worked fine on the xp box, but it fails on the windows 7 box.
More specifically, I've tracked it back to a specific subsection. It uses the Process library to start pscp, the putty scp command line tool. It has a timer to wait 400 seconds for the process to close, otherwise it stops the process and reports an error.
Unfortunately, on windows 7 it doesn't seem to even start the process, because it does not wait the specified 400 seconds, nor does it report the other error it would give if pscp did start, but failed. Is there a compatibility issue with the process library, or is it some configuration issue?
Update:
Alright, after more testing I've determined that the subprocess is getting spawned, but the parent is not waiting for it to exit.
it seems the VB code myProcess.WaitForExit(40000) is not actually waiting until the process exits. Is this because it can't 'see' the process and believes it has exited?
References Failing To Import To A VS 2005 (VB) ASP.NET Web Service Application Project
Aug 17, 2009I have this VB ASP.NET Web Service Application project running VS 2005. I'm trying to add references. To do so I click on the "Properties" icon in the Solution Explorer window which presents me with a window to add/update/remove references. I click "Add", I select the reference I want and then "OK". Lo en behold, NOTHING! It simply won't add references (I tried adding several different ones). Specifically I'm trying to add the System.Configuration assembly.

Manual Sorting For Gridview?
Feb 25, 2011I have done research on how to manually create sorting in a grid-view and none of it is thorough enough for me to follow. I need more of a step by step solution, like what event should my sorting code go in, how would i enable the headers to allow sorting. normally, i just have .net do this but for some reason this time it doesn't allow it, maybe because i am not using a datasource.that's my code that creates a datable and then binds to the gridview.

After clicking the button a message box appears and says, "Update is available for download" as you would expect but after clicking the ok on the message box my application goes into a not responding state and I have to close it with the task manager. The application builds successfully and I have a reference for System.Deployment added to the project. Everything in my application works fine as long as I don't try to do an update. Any suggestions on what I should check or do? It should actually say "no updates are available for download" since the version of the program that is being used is the most current version.
Databinding Manual Writevalue In .net Winforms?
Oct 28, 2009If I turn off automatic updating of a binding data source by setting DataSourceUpdateMode = Never and then use a button to update the whole lot (using binding.WriteValue), a problem occurs - Namely, only the first bound control's data source is updated. All other controls are reset back to the original values.This is because when the current object changes (as happens after the above WriteValue), if ControlUpdateMode = OnPropertyChange, then all the other controls re-read in the value from the data source.
One way is to derive a class from BindingSource and add a WriteAllValues method.This method does the following:
(1) For each Binding, save the ControlUpdateMode
(2) For each Binding, set ControlUpdateMode = Never
(3) For each Binding, call the WriteValue Method
(4) For each Binding, reset ControlUpdateMode to the saved value
(5) For each Binding, if ControlUpdateMode = OnPropertyChange, call the ReadValue method.
If working with your own classes, would implementing IEditableObject resolve the issue?In another control I'm working on, I implement my own binding. The way I get around the issue in that is with the following code. (I've put in the bare minimum, I hope you can follow it!):
Private Shared ControlDoingExplicitUpdate As MyCustomControl = Nothing
Private Sub UpdateDataSourceFromControl(ByVal item As Object, ByVal propertyName As String, ByVal value As Object)
Dim p As PropertyDescriptor = Me.props(propertyName)
[code]....
So, when UpdateDataSourceFromControl is called, all the CurrentItemChanged events will be called for all other controls in the same BindingSource. However, because ControlDoingExplicitUpdate is set, they will not re-read in the value from the data source unless they happen to be the control that did the updating.ControlDoingExplicitUpdate is set to Nothing after all these events have completed, so that normal service resumes.
DataGridView Databound And Manual Column
Jan 28, 2009I have a DataGridView on a form in VB 2005 Express, of the 10 columns i need on this DGV 6 of them will be pulled from an MSSQL DB and 4 of them i need to manually enter. One thing i have going for me (i think) is that the 4 manual columns have the same data in each row.I have been filling this DGV using a datatable, but i am not figuring out how to add manual columns and databound ones in the same DGV. My column layout would look like this:[code]some one please explain to me how i would do something like this. if you can include the datatable definitions also it would be a big help, in order for me to verify that i am at least doing that the right way.

Javascript - Automate Some Manual Tasks?
Apr 22, 2009trying to automate some manual tasks. The task to access a web page (asp) login and then get some details from the site. The challenge is that the home page after login is build of 3 frames. when i see the page view source from the edit menu all i see are frame names. Once i right click on each frame and view source i am able to see the complete source - variables javascript function etc. The following code helps me to navigate :
vb.net
Set ie = CreateObject("internetexplorer.Application")
Dim s As String[code]....
After this the page has been logged in. Now to proceed further i have to click a "image" object.
1) I tried qualifying the image like ie.Document..........item("img1").click this doesn't work
2) I tried calling the javascript function directly
ie.Document.all.Item("frame1").Document.parentwindow.execScript "JS_WGorUsers (funcname)", "javascript"
The 1st option gives a run time error and 2nd option says access denied. (if i login manually i am able to click the image.

View 3 RepliesAutomate FTP Download With Optional Manual Intervention
Apr 15, 2011I am looking to download several files from several FTP sites. Most of the time these files are all present by 08:00, but occasionally they are not there until a little later.Currently we have a bunch of excel sheets where the user goes into each and clicks a button which connects to the relevent ftp sites and downloads the files, performs some manipulation on them and then reports back to the user if the files exist, are empty, or if all is well.I am looking to redesign this, and was thinking I would encompass this within a Windows service which would have some sort of timer functionality which would start at about 7am, and end when all the files were downloaded whereby it would 'sleep' till the next business day.On the task completion it would send an email giving the information that was present in the current excel spereadsheets.
One thing with this is how often to poll the ftp sites to see if the files are there. I would ideally like to poll about once every 15 minutes or 1/2 hour, but if the user knows the file is present then they want to be able to invoke my process.One way of accomplishing this was to make the service a WCF windows service, so that it would run normally, and then if the user sends a request for amanual override, then the service would ignore its timer and run the process then an there.

My correct manual results and the NPV() results are close, within 5%.. but not the same...

The MSDN page example clearly states that the initial expense should be included in the cash flows list.

VS 2010 Added A Manual 'Refresh' Button
Jul 5, 2011I have an explorer-like interface which in many ways mimiques the behaviour of a standard explorer window. What I need is to find some way of knowing if something had changed in the filesystem since the last time I checked.What I mean, for example if a user creates a directory or renames a file - I need a way to know that. Right now I re-read the contents of the displayed folder once per second and I added a manual 'Refresh' button, but I wonder if there is a better solution.I tried to use FileSystemWatcher component for that but either I couldn't figure out how it works or it doesn't have such functionality.

Uploading To FTP Failing Sometimes?
Apr 28, 2011I am using My.Computer.Network.UploadFile(arg1,arg2,username,pass) & sometimes it returns an error to me about not being logged in?I keep using IE & such to visit the ftp'd pages & even login & logoff the ftp site server at times, but seemingly randomly it will fail, even if I use try catch statement, it seems to keep wanting to fail till i go back to IE & go to a webpage on the server or log back in to the account management through IE.
Should it not be authenticating & working correctly each & every time regardless unless the server can't be reached? Why is it wanting to fail SOMETIMES when closing these webpages/logging out on IE only, why is this seeming to have any bearing on this failing in VB.
WebRequest Failing After A While?
Aug 4, 2009I have a series of WebRequests in my app all formatted like this
Try
request.Timeout = 30000
' Get the response and read it to the end [HTML of a page]
[Code]....
After roughly 250 iterations of about 5-6 WebRequest per iteration, the app hangs and starts hitting the WebException "The remote name could not be resolved: 'hostnamehere' ". WebPages also don't load through my browser when this happens, I have to close the app for my internet to work again. This app is multithreaded and I was testing with 100 threads (in a threadpool, MaxThreadCount set to 20, addressof the sub which performs the WebRequests). A test with 20 threads yielded identical results - Same WebException also right around 250 iterations processing the same sub. I have tried setting the ConnectionLimit of the request to the thread count with no luck.
Data-bound Dropdownlist That Permits Manual Entry Also?
Aug 16, 2011I am not a .net programmer but I can write bits and pieces that I need, however, I have been having trouble working out the best way to achieve something for a website I'm altering.I basically need to have a drop down list which is bound to a certain SQL call (already in place) but I also need the ability to manually type into the drop down list for items that do not exist. These items do not need to be entered into the SQL (I can handle the additional data separately) but I cannot find a way to type inside a drop down list while it is bound to a datasource.Some entries in the datasource (SQL table) are used for one thing, but then a text string needs to be entered for optional entries which do not exist within this SQL table.
Does anyone know how I can achieve this or maybe another similar control can be used that offers this kind of functionality?**Update to be more clear:I need this at runtime. For instance, I do not need this to be within code I actually need the control to accept user input when someone is on the webpate.Imagine a shopping list and all the items are within the drop down list then the user wants to add another item to the shopping list so they just type it into the drop down box and submit the page and its value will be used instead of an existing item.
