I want to create one script that will open the windows application and use that application to perform some task. I have listed out the activity that I want to automate below:
Application is PTC integrity. It is linked with database server that has lot of files in it which have unique ID. So I need to use ID to open the document and export it.
Steps:
Open the application.
Open the document using ID.
Export the document to some specific format.
I want to know which scripting to be used to automate this process, i.e., I give array of IDs , the script will open the application and then open the document using IDs and export them till all the IDs are exported. Using Excel VBA can it be done.
Yes you can do this in VBA.
Your VBA can call a batch file via the Shell command that uses PTC Integrity Command Line Interface.
To export a document you can use the 'im exportissues' CLI command.
To call a batch file synchronously you can use the ShellandWait function below or see related StackOverflow question.

I have a macro that send me a text from outlook when a meeting notification pops up. I would like to figure out a way to make that macro only run if I am not at my computer. I have looked for a way to pull my status from Skype for Business, determine if the PC is locked or not, and see if a smart card is inserted. All without much luck. Looking for a simple solution that works in VBA.
I used the code from here Determine if application is running with Excel
Function IsProcessRunning(process As String)
Dim objList As Object
Set objList = GetObject("winmgmts:") _
.ExecQuery("select * from win32_process where name='" & process & "'")
If objList.Count > 0 Then
IsProcessRunning = True
Else
IsProcessRunning = False
End If
End Function
Based on the answer here In Python 3, how can I tell if Windows is locked?
I called
IsProcessRunning("LogonUI.exe")
and it seems to work.
Maybe this is of any help

I'm making a tool, where I need to start a programm (which I want to code with VB) by using VBA in an Excle file. When I close that programm, it should give back a parameter to the VBA script.
I started just now with the VBA script and didn't code anything of the VB programm yet. But I need to know, what to write in the VBA script and wheter this is possible.
So it should work like this:
I'm in the Excel file and I press a button
The programm is starting (also getting a parameter from the Excel file, this is not that important yet)
In that programm I configurate some stuff
Closing that Programm it should give back a ID of that configuration
I'm getting back to the Excel file with this ID
Is this possible? And what do I need to write in the VBA script and in the Programm to give back a parameter?
I hope you understand what I mean and you can help me
You could set your VB .exe to return an Exit code. Just make sure the id isn't 0 (means ran successfully) or 259 (calling process will think process is still running). The VBA below runs an .exe, waits for it to close, then returns the exit code.

I am building a Windows Forms Application on VS2010, through which I need to execute a 3d party DOS shell program (OpenSees.exe), open a source file in it and perform an analysis. After this, some output files are created which I need to read again in my VB.NET app.
The thing is that the analysis in OpenSees may take a long time, so the VB code has to wait for it before carrying on.
For this, I have tried both "ShellandWait" sub along with "WaitForSingleObject" function and "process class" option, but neither of then works.
My DOS shell program initializes, but it closes almost immediately, not letting the analysis to complete and the required output to be created.
Here are the code snippets I used:

I've been spending the last few hours trying to figure out how to save a file onto the computer using VBA. The code template below that I found on another forum seems promising, except when I go to the desktop to access it, the .csv file has what looks like the page's source code instead of the actual file I want. This may be because when I go to the URL, it doesn't automatically download the file; rather, I am asked to save the file to a certain location (since I don't know the path name of the uploaded file on the site).
Is there any way to alter this code to accommodate this, or will I have to use a different code entirely?

http://www.excelforum.com/excel-programming-vba-macros/925352-vba-go-to-website-and-download-file-from-save-prompt.html
I found over the years more ways how to save/download data using vba:
The firs option witch I prefer and would recommend is to use the URLDownloadToFile function of the user32 library using the following solution
The second one which was also mentioned be yourself. The point here is to use the Microsoft WinHTTP Services (Interop.WinHttp) COM library. In order to achieve this you can also add the Interop.WinHttp reference to your project link. After that you are able to use simpler notation like here link
The third option I aware is to ask the browser to save it for us and then using the Save_Over_Existing_Click_Yes function was mentioned by Santosh. In this case we open an Internet Explorer using the COM interface and navigate to the proper site. So we have to add the Microsoft Internet Controls (Interop.SHDocVw) and the Microsoft HTML Object Library (Microsoft.mshtml) references to our project in order to gain intellisense feature of the editor.
I don't like this download method because this is a work around by hacking. BUT if your IE session was already established authenticated etc. this gonna work nicely. The save function of the Internet Controls was dropped because of security concern. See for example: link
Newer the less you have to have the correct url to download what you want. If you pick the wrong one you will download something else :)
So please try to make sure the the url you use is correct by enter it in a browser. If it opens the right .csv file than your source could work too.
Also please try to send some more information: for example the url to the .csv file
Try below code :

I am developing an application which opens and reads an XML document previously embedded in a PowerPoint presentation, or a Word document. In order to read this object (xmlFile as Object) I have to do:
xmlFile.OLEFormat.DoVerb 1
This opens the package object, and I have another subroutine that gets the open instance of Notepad.exe, and reads its contents in to ADODB stream.
An example of this procedure is available on Google Docs:
XML_Test.pptm.
During this process there is a few seconds window where the Notepad.exe gains focus, and an inadvertent keystroke may cause undesired results or error reading the XML data.
I am looking for one of two things:
Either a method to prevent the user from inadvertently inputting (via keyboard/mouse/etc) while this operation is being performed. Preferably something that does not take control of the user's machine like MouseKeyboardTest subroutine, below. Or,
A better method of extracting the XML data into a string variable.
For #1: this is the function that I found, which I am leery of using. I am wary of taking this sort of control of the users system. ##Are there any other methods that I might use?##
Private Declare Function BlockInput Lib "USER32.dll" (ByVal fBlockIt As Long) As Long
Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sub MouseKeyboardTest() 'both keyboard and mouse blocked
BlockInput True ' Turns off Keyboard and Mouse
' Routine goes here
Sleep 5000 ' Optional coding
BlockInput False ' Turns on Keyboard and Mouse
End Sub
For #2: Some background, but the issue seems to be the inability to extract the embedded object reliably using any method other than DoVerb 1. Since I am dealing with an unsaved document in an application (Notepad) that is immune to my VBA skillz, this seems to be the only way to do this. Full background on that, here:
Extracting an OLEObject (XML Document) from PowerPoint VBA
As you correctly guessed in the comment above that taking the focus away from notepad will solve your problem. The below code does exactly that.
LOGIC:
A. Loop through the shape and get it's name. In your scenario it would be something like Chart Meta XML_fbc9775a-19ea-.txt
B. Use APIs like FindWindow, GetWindowTextLength, GetWindow etc to get the handle of the notepad window using partial caption.
C. Use the ShowWindow API to minimize the window

My understanding is that you have control over how XML file gets embedded into PowerPoint presentation in the first place. Here I do not quite understand why you chose to keep the data you need as contents of an embedded object.
To be sure, the task of getting those contents back is not a piece of cake. Actually, as long as there is no (simple or even moderately difficult) way to call QueryInterface and use IPersist* interfaces from VBA, there is just one way to get to contents of embedded object. The way involves following steps:
Activate an embedded object. You used OLEFormat.DoVerb 1 for that. A better way would be to call OLEFormat.Activate, but this is irrelevant for your particular problem.
Use embedded object's programming model to perform useful operations like getting contents, saving or whatever is exposed. Notepad.exe exposes no such programming model, and you resorted to WinAPI which is the best choice available.
Unfortunately, your current approach has at least 2 flaws:
The one you identified in the question (activation of notepad.exe leading to possibility of user's interference).
If a user has default program for opening .txt files other than notepad.exe, your approach is doomed.
If you do have control over how embedded object is created then better approach would be to store your XML data in some property of Shape object. I would use Shape.AlternativeText (very straightforward to use; shouldn't be used if you export your .pptm to HTML or have some different scenario where AlternativeText matters) or Shape.Tags (this one is probably the most semantically correct for the task) for that.
I don't think that blocking the user is the right approach,
If you must use a content of a notepad window, I would suggest using the SendKeys method, in order to send this combination:
SendKeys("^A^C")
Which is the equivalent of "Select All" and "Copy",
And then you could continue working "offline" on the clipboard, without fear of interference by keystrokes.
My approach, per Sid's suggestion, was to find a way to minimize the Notepad.exe. Since I already found way to get that object and close it, I figured this should not be as hard.
I add these:
Public Declare Function _
ShowWindow& Lib "user32" (ByVal hwnd As Long, _
ByVal ncmdshow As Long)
Public Const SW_MINIMIZE = 6
And then, in the FindNotepad function, right before Exit Function (so, after the Notepad has been found) I minimize the window with:
ShowWindow TopWnd, SW_MINIMIZE
