MSDN If GetModuleFileNameEx Succeeds It Should Return The Length Of The Path Name
Jun 25, 2009
I am new to the Window's API and have been trying to just poke around with it. It was suggested to me to try making a time tracker program that will track how long a window is actively being used and keep windows from the same .exe file grouped together. Things have been going good so far, but I am having trouble with the GetModuleFileNameEx command.
According to MSDN if GetModuleFileNameEx succeeds it should return the length of the path name; however, when I output the return value of GetModuleFileNameEx, it is just a random long number that changes with every tick of the timer. Also when i try to output the path of the open window just to see what is being stored there, it is blank. I have googled and surfed the net for but to no avail. I was curious if someone here might have an answer for me Here is the code I am having trouble with:
How to insert a point along the path without changing its pattern?
and how to get a nearest point along the path with a given point? or
get a on-path-point with a given percentage of the length of the path, e.g.: 3/4 of Path(new point(){(0,0),(2,4)}) = (1.5,3) (like Adobe Flash, the object can follow a path to move.)
I have tried to measure length with Graphicspath.flatten, but it takes time and not accurate enough. Is there a formula to do that?
My issue is to combine two paths which one or both of them may contain double dots. I used Path.Combine(string, string) and the returned string is still a long path as a result of concatenating these two paths. Single or double dots are not eliminated.
So, I tried to use Path.GetFullPath(string) method with the concatenated path as the argument.PathTooLongException is thrown because this path has more than 260 characters. However, if this path is normalized, it won't exceed the maximum characters for a file path.
My system has Japanese regional settings. I have used this as default encoding in my code. But Encoding.GetString() method doesn't return proper length because of DBCS.[code]
I get a message, "The MSDN collection does not exist. reinstall MSDN." When I try to access any of the HELP features of Visual Basic 6.0. I do not have an install disc for this. Is there a download or a place I can get this?
on vista trying to create a reference to a registered DLL which succeeds with VS2008 but not with VS2010 (get system cannot find the reference specified).on vista and win7 using dependency walker the DLL cannot find IESHIMS.DLL which is in the IE folder.
I am using the open file dialog box. Right now the function looks like
Private Function OpenFileDialog1_FileOK(...) File_Path_Name = OpenFileDialog1.Filename.ToString() End Function
The thing is it isn't clear when this is called. I think it is called when I go through OpenFileDialog1.ShowDialog()
I want to return a value that is the Filename path to a variable like file_path = Function() and not use a global variable. But it doesn't seem like this is possible. Do you know how to get the function OpenFileDialog to return the file path?
I have one small problem on my app, here's the deal, when I run my app that have a button for "load playlist" and when I click on file>options my app is looking for settings.xml (created before by the same app) on the same folder from where I loaded my playlist. Load playlist button is on my Form1 and Form4, and settings is on my Form6, and this happend every time I load anything, open anything, so my app remembers last opened folder. Is there any way that I can return my path to apps path? I need to mention that this applies only to Windows XP, idk why, because on my win7 it works just fine.
How would I retrive the folder name a file is in? In this example I just want the highlighted folder name: C:Program FilesFolderNameIWantApplication.exe I can get the path excluding the file using various methods such as:
So basically, I am running through my selected path recursively and returning the results to an array.. I think. vb.net Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim path As New FolderBrowserDialog If path.ShowDialog = Windows.Forms.DialogResult.OK Then Me.TextBox1.Text = path.SelectedPath [Code] .....
I was told that to return the search to an array, I add the return toarray() at the end. Now obviously Im not getting errors, but I am also not polling the results that are in fileslist.toarray(). I've looked at arrays quite a bit, I see their functionality if they are defined like myarray(4) with 5 declared array values... its an array with 5 value places. And to read from any one of the 5, you'd say something like msgbox(myarray(3)) to call the 3rd place in the array.
Well, as you can tell from the code, I am putting a variable amount of information into the array, How can I call that information? If I scanned a folder with 300 files, how can I call the results of that array and put them in a text file, or console, or messagebox through them? And assume I am doing it through a button click event. So, button click to read all input in the array to console or something like that.
in an winForm app in VS2010 win 7 compiling to x86, I try to do what Alvas.Audio seems to work. See (c# ex: [URL] for reference.
Dim data() As Byte = wr.ReadData(second * i, second)
The result give me data.length()=0. I do not have any exception, I can read format from it and whatever reader I use I got this problem.EDIT : After some tests, it seems like the uncompressed file I create in the first step (in PCM format, with .wav extension) can not be recognized by the Alvas.audio library for the second step. I must miss something around Audio file markups or something alike.
Here is the code that might be the source (basically this is step 1):
Dim functOut As String = String.Empty Dim wr As Alvas.Audio.IAudioReader = Nothing Dim fs As IO.FileStream = Nothing
[code]....
How can I write the resulted stream to be sure I can read it again later?
I'm using Microsoft Visual Basic 2008 Express Edition. I have a Folder Dialog Browser added in my form and I call it when the user presses a button. The folder path string is stored in a string variable and displayed as text in a text box. (maybe I should use a combo box)
My question is: If the user inputs by hand a non existent path, how do I return an error message, stop the file creation into the invalid path, and return to my main form?
I'm running windows 7 64 bit and using VS 2010. I'm trying to use the filesystem.getfiles to find a file on the computer and return the path for it. However, when I search C:/ and its subdirectories, it always throws an error: "A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll"
I've looked everyone online and can't find a solution. I have administrator privileges and really I dont want people who use my app to have to adjust security settings for this to work. Is there not a way to search the C drive for a specific file and return its path? [Code]
End WhileI am trying to read from the ": " to the end of the line. I keep getting this error: Index and length must refer to a location within the string. Parameter name: length
I have a field displaying on a datagrid that the user has asked to be variable length based on the data that is returned. Is there an easy way to determine how many characters are returned for a field and then converting that to a pixel length so that I can change the length of the field in the code.
I have a Access program and I'm using VBA code in the background to run Winunzip using shell command. Well, the path of the .zip file has spaces in it and it's not recongizing the path as a valid path. Is there a another way to tackle this problem besides the shell?I can't us pkzip either. Has you can see I had to use progra~1 instead of Program Files.[code]
If using the following in an if statement I get an error: If trg.Name.Substring(4, 6).ToUpper <> ("ABCDEF") Then I get the error: "Index and length must refer to a location within the string. Parameter name: length"
I assume this is because the string (trg.name) is too small for the 4, 6 substring. What would be the correct method of working around this problem? VB.net Studio 2008.
I'm a developer for a College we have an active directory.I need to query Active Directory with the Pc name and return it's path in the Active Directory tree.
The regularity and frequency of that extolling is an indication of how many people, for whatever reason, don't use the documentation. Some say that I've forgotten what it's like to be a beginner, but I remember using the MSDN documentation as a beginner. I remember that I couldn't always find what I needed and I also remember that I didn't always understand what I found. More importantly, I remember that that didn't stop me using it first every time I had an issue and I also remember getting better at using it over time. So, I'm genuinely interested to know, if you don't use the MSDN documentation?
I just recently installed VB 6.0, and I went to install MSDN Library (April 2000 Release of the MSDN Library)afterward. I was missing CD 2, but installed the other 2 CDs. It appears CD2 is the primary one for VB. Do you know how I can get this specific CD --OR-- can I just download a newer version (i have been looking for both on MSDN with no luck)?
MSDN online looks completely different. It used to be a set of collapsible controls. Does it still contain the same content? Is it under construction due to the release of 2010?
if you are a constant answerer here on msdn, and do not have a unique signature, or no signature at all, please take a little time to create one... eason ..when quoting a post of a member, if no signature available, then it would have to be followed w/ "quoted from so and so's post", this so so said this, etc.
I'm using VS2008 with all updates current. When programming with VB, I set the MSDN Help language to Visual Basic, but I very frequently get results for C#. Why does that happen and is there a reliable way to prevent it? I know C# and can adapt the results to suit my needs, but I thought using the filters was supposed to restrict results. Apparently, it doesn't. I'm just curious; why does that happen?
