In my last information seeking I found the answer on a systemic level.

Now, I need to find data on the process level and it is documented in a far sparser manner than I am used to seeing. I dont know if the answer is in psapi.dll or kernel32.dll is. I don't know what approach to take since there is little information.
I have a form that consists of only a TableLayoutPanel (which fills the entire form) containing a vertical stack of buttons. The resulting app is used in conjunction with another app. What I would like is to have the vb app do something when the mouse enters the form. Unfortunately, all mouse enter/leave events are trapped by the panel or the buttons.
As a quick test I created a form with a tablelayoutpanel (docked to fill the form) containing one button. I added the following code:
Private Sub Form1_MouseEnter(sender As System.Object, e As System.EventArgs) Handles

View 1 RepliesI have a 32 bit application that shells a second application that can be 32 or 64-bit depending upon the computer it's running on. I only want one instance of the second application to run at a time, and I need the first application to prevent the second from being launched more than once. I want to be able to use GetProcessesByName to obtain the running processes. This seems to work fine. It's when I attempt to obtain the module data to find out what folder the second application was run from that things fall apart.

I am creating an Excel add-in written in VB.NET. I would like to bind KeyDown and KeyUp events to the spreadsheet to record when the user presses and releases the arrow keys while navigating the spreadsheetIdeally, these events would be built into Excel alongside the native SheetActivate and SheetSelectionChange events, for example. Alas, they are not.

Using process.start ("filename"), i was able to run the exe file. After that i send Alt U to Unzip the content.. Finally the Self Extractor sends message "xx files unzipped successfully..." or similar...
Now, how do I find out the the extraction is completed or the msgbox "xx files unzipped successfully..." popped up ? (I don't like to go thru the window title as there might be other thing going on...)

what I am trying to do its to automate a user interraction by code.First I have a button named "start" once pushed I navigate with webbrowser to download a file. What I try to do it is to find the window "File download" by his title name, I allready made a seperate thread to loop into to list of process until it found the window "File download"
Where I need help, it is with the process list. I try that code below but I don't see the process "File download" in the list.and once I found it I would like to use sendMessage() api to simulate the click of save.I would like to find another window after to catch the window "save as" and click save and if the window that ask for overwriting appear I would like to find it too and click yes.
Why I use webbrowser instead of httpwebrequest it is because the web site required to login, i try using cookie, etc. No success so I decided to use webbrowser, I navigate first into the login page, I login manually and once it is done I can click the button to start downloading. I want to make an automatic download loop, I have lot of files to download on that site, sometimes .doc and other times it is .pdf
I didn't found a way yet how to force webbrowser to ask for downloading .pdf instead of opening it in acrobat, if someone can help me for that point too

I have created a simple program which uses a two tier structure of SQL Tables.At the top level, one record holds the date of the activities and linked to it using its primary key as a foreign key, three subordinate tables hold time stamped records.The issue I have been unable to solve is that before adding any of the lower level records for a given date, a newly added top level record must be saved to the database.Doing this manually is simple - but can I rely on my users to remember to do this before they start plugging in the lower level data?I thought not, so I am looking to save the top level automatically.I've failed miserably but I refuse to believe that it's not possible.

I am attempting to make a piece of software that monitors a 3rd party process for injected code. I successfully made a program that uses readprocessmemory from kernel32 to search for strings in a process. My problem is that the process I am attempting to monitor is running as system and provides an access denied message when I attempt to query any information about the process. Including process.handle and process.modules. Are there any ways I can get this process' handle?
View 4 RepliesI'm fairly new to vb.net and trying to get information for a project at work! Basically I can list all the applications running on a machine, I cannot however retrieve the details of the user running it! At the moment I'm using the following code after importing System.ServiceProcess and System.Diagnostics.Process:
Public Sub GetProcess()
Dim pr As Process
A = 0
For Each pr In Process.GetProcesses(System.Environment.MachineNam e)
ReDim Preserve arrProcess(A)
arrProcess(A) = New String() {pr.ProcessName.ToString, Process.GetCurrentProcess.PrivateMemorySize64}
A = A + 1
Next
End Sub
I have tried using pr.StartInfo.UserName but that just returns the username of the person logged onto the machine.
I have a question about event handling. Is it possible to detect field level data change in vb.net? i don't want my codes to be dependent on the the bound control's event to detect the change on the field value. I'm thinking there must be a better way (coming from a Delphi background). For example: a change on the Qty field will automatically trigger the event to compute the invoice detail Amount - (pseudo-case sample: Amount = Qty * UnitPrice).
In Delphi, every field is treated as an object with its own properties and events. So it's very easy to associate an event with it.
Example:
procedure TfrmInvoice.qryInvDetQtyChange(Sender: TField);
begin
inherited;
qryInvDetAmount.value := qryInvDetQty.AsInteger * qryInvDetUnitPrice.AsCurrency;
end;
How can I achieve the same using vb.net?

I have a context.Request.QueryString item that is returning the wrong value in the ProcessRequest method of a .ashx handler.
The code is like so:
Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest

End Sub
One of the values returned by "OrderItems" is wrong. How can I find out what process has called this method to fix the incorrect data?
I have a process serves as an application updater.It checks it's local cache of files and compares this against list of files online.On it's first run there are no files in the local cache and it therefore downloads ~100 of these files.[code]This appears to work very well, since Explorer confirms that all files are extracted and available.However when I later run this process again, it cannot verify the existence of 6 of these files and therefore tries to download them despite the fact that they are clearly both present and up to date.The offending code is a simple File.Exists call which appears to deny the local existence of these files, and therefore tries to get them again.The system continues to work well, but over time the continual downloading of these 6 files is going to get kind of silly.
View 1 RepliesI have multiple level of For Each and in each level, i have a Linq that is the 'In' criteria as in:
[Code]....
It will go inside each for (because the value is not nothing), however, it will only loop (next) in the very inner 'For Each t In tFor'. After it is finish inner loops, the outer Fors' or Next will not execute... even thought there are more than one values in that 'In'... like 'sFor' or 'fFor'. i've noticed while debuging, while break at the for (for example 'sFor', before stepping in), i get the error message:
"Enumeration yielded no results" when i expand the result for that variable and it will not step into it. but if i do not expand the result, it will step in. It seem that some how, once an element is accessed for that 'In' collection, it breaks (meaning does not loop for the rest of the elements) the next for that collection is this a bug or am i missing something in Linq? BTW: i believe it has something to do with the SqlDataReader in the Linq. I'm working with IAsyncResult.
