I have used one error handler code in my all vb6 projects,
Now I have to remove that error handler code which is in all sub procedures, functions.
I have to remove it manually all the time can it be removed automatically
I approached a task similar to this one time by writing a small program that would
1) read the project's vbp file and retrieve the names of all the files in a project
and
2) would then edit each of these files and make the desired changes.

I'm working on a project where I need a script to execute when someone hits "F5" or "F6", even if the code in the project hasn't changed.
The script is responsible for copying data from a different directory - data that may have changed.
I've noticed that this works properly as a post-build event, but only if the project is actually rebuilt. How do I get the event to trigger without requiring a clean each time?
These are the steps I followed to setup the script to run when I needed it:
Opened Project > Properties
Navigate to Custom Build Step > General
Put the script command in the "Command Line" field
Set an arbitrary output filename (this is required, if you don't have an output filename, visual studio will skip your custom build step) I chose an arbitrary filename ".filename" if I were to get fancy I'd also have the script output a log to this file
Set the "Execute After" field to "FinalizeBuildStatus" This ensures that the command will execute after the build status has been established (which happens in all circumstances when you'd hit F5 or F6, even if you haven't changed any code in the project).
I was surprised not to find these steps clearly outlined elsewhere online. Perhaps I'm bad at googling, but since I solved my own problem I find it only fitting to share in case someone else has this problem.
I have a VB6 project that I didn't create but I have to update, when I go to make the exe I get a compile error: Method or data member not found, and it points too "SCom1.FileReceive" in the code below. When I look at the Main form, the SCom1 control is a PictureBox.
This code has been working for the last 5 years but I don't know why SCom1 is a picturebox, or why I'm getting the error, is it a reference? SCom1 to me looks like a MSComm function? Let me know if anyone has any ideas, I just don't know VB enough to know how to troubleshoot this. Thanks
If SCom1.FileReceive = True Then
WriteToLog (Now() & " FileReceive was true, now false")
SCom1.FileReceive = False
End If
The machine which you have opened the code doesn't have the mscomm32.ocx file or the ocx file not registered properly.
When vb cannot reference an ocx, it'll convert the relevant control to a picture box control.
What you have to do is, close the project without saving. Then open system32 folder and check for mscomm32.ocx file. If the file is not there then you have to download that from the intenet. The register the file using regsvr32 command in command prompt.
After this you can open the vb6 project and start working.
=========================================================
EDIT : Included the update in the comments to the answer, this will help other users in the future... :-)
if the method name doesn't look familiar to a known ocx file (in this case the SCom1.FileReceive), the missing component can be a custom ocx file.
So check on the working machine or in project folder whether there are any ocx file exists in the relevant name (in this case SCom.ocx).
if there is a file exists in such name, register that file using regsvr32 (if not registered), then add that to toolbox, then replace the picture box control with the relevant control (make sure the name tally).
Whenever I press on the open in IE icon, I get an error in the console:
Error: NS_ERROR_FILE_NOT_FOUND: Component returned failure code: 0x80520012 (NS_ERROR_FILE_NOT_FOUND) [nsIProcess.init]
Source File: chrome://openinie/content/openinie.js
Line: 126 (This happened ever since upgrade to 16.0 and I assume it's probably security related)
I found that js file to be inside some "openinie#wittersworld.com.xpi" file (which I cleverly renamed to zip), and saw the offending line:
var iePath = openinie.getIEPath();
// create an nsILocalFile for the executable
var file = Components.classes["#mozilla.org/file/local;1"].createInstance(Components.interfaces.nsILocalFile);
file.initWithPath(iePath);
// create an nsIProcess
var process = Components.classes["#mozilla.org/process/util;1"].createInstance(Components.interfaces.nsIProcess);
process.init(file); // <-line 126
is it possible to fix it and "re-compile" it zipping and renaming?
(I assume it's something with security maybe).
can I debug this using for example an alert box to display values of variables?

Yes, you can simply replace a file in the ZIP archive, most extensions aren't signed (you can remove the META-INF directory from the XPI file if this one is). In fact, for your debugging it is better to unpack openinie#wittersworld.com.xpi into a directory named openinie#wittersworld.com in the same folder and remove the original file - this way you won't need to pack/unpack on each change. You should also start Firefox with the -purgecaches command line parameter, otherwise the file you are changing might get cached.
can I debug this using for example an alert box to display values of variables?
Yes. However, I would rather recommend Components.utils.reportError() method that will log to the Error Console (press Ctrl-Shift-J to open it) without opening modal dialogs. In this particular case I would write:
Components.utils.reportError(iePath);
This seems to point to a non-existent file meaning that the getIEPath() function is faulty.
Good luck!
Here is my app status:
Purpose - download multiple list files from internet
Approach - created a simple "download form". After a while, I just needed more forms because I had more than one list of files to download. Just solved that by adding a MDIform to my project, add a button to create another "download form" instance and voilà. Apparently, my problem was solved. But no :(
When I press my "download" button in my form-instance3, the other form instances (2 and 1) hangs on downloading the contents (I get a timeout sometimes) until the form-instance3 terminates all the downloads and so on, for all the other forms. So, even though I know my app is not multi-threaded, the multiple instances of the same form are in conflict (Inet component, presumably) and I can't download multiple files at the same time.
Inet and my download function are defined in the form.
What can I do to solve this? how can I download multiple files at the same time?
edit:
I'm trying to use the "wqw" suggestion, but I'm facing some problems:
In the download_form, I have a MSHFlexgrid, with 2 columns: one with the URL and the other with the file destiny. I was iterating throw all rows to download the files and save them. With the approach suggested by "wqw", how can I distinguish each download so that I can save it with the properly name indicated in the grid?
What do you use for the actual http download? I would try Simple Asynchronous Downloads and forget about the MDIForm. Really!
VB6, on its own, is single threaded. So breaking out downloading to different forms won't help you.
What I've used in the past is the Timer object in conjunction with an ActiveX EXE. This approach will give you an ability to localize all the downloading logic in one place, control it like you control a regular object and have it run in a separate EXE, thus by default making it multi-threaded.
So the way this works is like so:
You call the Download method on the ActiveX EXE object
In the download method, you instantiate the Timer and have it kick off almost immediately.
You get out of the Download method, thus giving control back to the entity that called it.
Then you communicate back to the main app via Events (e.g. DownloadProgress or DownloadComplete, etc...)
I am working on a game using the XNA framework. My game has several levels which I am storing the data in a plain old text file. In VS 2008 when I add the level file to the project and compile, I receive the following error message.
Error 1 Cannot autodetect which importer to use for "Levels\0.txt". There are no importers which handle this file type. Specify the importer that handles this file type in your project. F:\Projects\BrickBreaker\BrickBreaker\Content\Levels\0.txt BrickBreaker
The reason I am bringing this out is because if I change on of my levels and run the game, the level is not updated. I have found that the level is not updated because VS runs the game from the bin\debug folder and since the level files are not included in the project, they are not copied when they change. I also found that the platform sample that comes with the framework includes the level data in the project, that's where I got the technique from.
So, should I use a different file format or just deal with having to manually copy the new level files over?
Resolution - After digging into the answers on this post I found a solution. I added the text files to the project and set the build property to none. The error no longer occurs when compiling and the file is included in the project.
You can have Visual Studio just copy over the files if you want to the output directory. Under the properties of the text file in the project, choose Build Action: None and change the copy to output directory to as needed.
You can also check out the platformer sample. They use text files as their level format.
There is no content importer for text files. Ignore the content pipeline and just read the file in just as you would any other normal text file.
string line = string.empty;
using(StreamReader sr = new StreamReader("filename")){
while((line = sr.ReadLine()) != null){
//reads line by line until eof
//do whatever you want with the text
}
}
I had similar problem, and found it easier to have the files added to content project, and build action set to none, than to skip content pipeline altogether.
