Im new to VB.net in fact before then i hadnt touched VB since 5... in either case, im using VB to write Scripts to interact with Macromedia flash. Pretty much all it does is create these scripts out of a database and then Starts them as a process. Part of System.Diagnostics... My problem is Macromedia Flash has alot of overhead and reacts slowly, also after the loop i need to reorganize all the files. Ive got everything set up to do this. But VB is running too quickly, once the loop is done, it deletes the files, before flash is done with them. Thus causing an exception. Is there anyway of SLOWING down VB?

You really can't change the execution speed of the code. I'm no Flash developer by any means, so...
The only thing you can do is try and find some kind of event or something else appropriate that can signal your app that Flash has completed its job. Watching for this event will be the tricky part. I have no idea how to do it or what to watch for.
Also, you could put your app to Sleep for X number of seconds, but it's very unreliable considering you can't determine ahead of time how long you have to wait for Flash to finish.

I would also see if you could find a better way to do this, but in case you are interested, you can use one of the system.Threading.Thread.Sleep overloads to pause your app.

I have some color settings that I want to obtain when one of my forms load from an ini file to which the values in the file were set using the Color.toString method -> Color [A=255, R=255, G=128, B=0] or Color [Maroon]. I know there is the ColorConverter class that would be able to translate the Maroon color after I extracted the color String, but is there an easy way to extract the color from the string containing the numeric values? Or is there a better way of outputting the color to the ini file instead of using the toString method?
Thanks for the help.

I'm Not sure if this is what your after...
Imports System.Drawing.Color
Imports System.Drawing.SystemColors
Dim colorTrans As ColorTranslator
Dim cRed As Color
Dim cBlue As Color
Dim cGreen As Color
Dim intRNo As Integer
Dim intGNo As Integer
Dim intBNo As Integer
cRed = colorTrans.FromWin32(RGB(intRNo, 255, 255))
cBlue = colorTrans.FromWin32(RGB(255, intGNo, 255))
cGreen = colorTrans.FromWin32(RGB(255, 255, intBNo))

Hi
I am using FSO (Microfoft File System Object dll) to move TIF image files from a network shared folder A to another network share B in vb6.
If I want to move a single file from A to B, does the number of images in either folder matter in terms of effects on speed?
I am experiencing an huge slug in speed if I increase the number of files in A, even if I want to move only a small fraction of the files in A to B.
My thinking is that FSO actually has to search for an image before moving it.
Is there a difference to FSO (or Windows 2000 file system) if folder A has 20,000 files compared to when folder A has 100 TIF files?

If your using the FSO Folder class, then yes, there is a huge difference in speed. This is because the Folder object is enumerating all the files in the folder to populate its Files collection.
If your using the FSO.CopyFile method, no there shouldn't be a huge difference in speed, but there will be a difference. Unless you have those 20,000 files sitting on a FAT volume...please say it isn't so!

I was wondering if anyone knew how to make a link to a file in your directory from inside a textbox. What i have is a list of files that the user selects placed inside a textbox. I would like to make it possible to link to each of those files but am unsure how to do it. any help? thanks in advance!!!

What do you mean by "link"? Put a shortcut on the desktop, or open the file, or what? You'll have to be more specific as to what your refering to.

sorry for being so vague. What I am doing is listing user selected files with their paths inside a textbox. I would like to make a link from these files so when you click on them you open them up. They are pdf files. Would a richTextBox work or a listBox? thanks for your help!!

ListView would be the way to go. Each line is click-able and double-click-able, so you able to handle each of these events on a line-by-line basis. All your doing is adding the path (a String) to the ListView's Items collection. When the user clicks, or double-clicks, on a line, your code can use the Process classes to start the .PDF file that was clicked on.

Try to find any document about RichTextBox control. You might be able to do it as what you want.

Are you sure you want to use a textbox??? try a listbox. It´s waaaaay more efficient for such a task as the one you describe, because you can use the _DblClick() event:
------- 8< code 8< -------------------------------
Private Sub List1_DblClick()
Shell List1.List(List1.ListIndex), vbNormalFocus
End Sub
------- 8< code 8< -------------------------------
Hope that helps.

Exactly. Each line of the 'list' would show something like:
1----------------1/\
1c-standards.pdf 1*1
1vb_reference.pdf1 1
1my_book1.pdf 1 1
1etc.pdf 1 1
1-----------------\/
And when you 'Dbl_Click()' on any item (...with the code I showed you) you´ll exec every file to launch the default pdf reader and show it to the user. neat

PS:any other doubts?

Is there an easy way to clear multiple controls?
Fore example; I have 20 textBoxes, 10 radioButtons and 5 checkBoxes in a form. Is there a single command that will set ALL:
textbox.text = ""<br />
radioButton.checked = False<br />
checkbox.checked = False
Thanks
Brad

No, there isn't. You'll have to create a function that enumerates and clears them, one by one.

I think you could use control array to do that, for example:
dim i as integer
dim j as integer
dim k as integer
for i=0 to 19
txt(i).text=""
next
for j=0 to 9
rdb(j).checked=false
next
for k=0 to 4
chk(k).checked = false
next

There are no control arrays in VB.NET like there were in VB6. You have to enumerate the form's Controls collection to get at them.

Anybody know how to add icons to listview columnheaders? I tried and I did not know how.
|
|
|
|
|
Ok, this is a pretty complex and long one...
*) First of all you need to add an 'ImageList' control to your project, and insert the images that are going to be icons on the listview.
*) After you´re done with that, go to the listview´s property page and go to the 'Image Lists' tab. Set the appropiate 'ImageLists' to each option.
*) On the code:
Listview1.ListItems.Add , , "Hello!", <image_index_corresponding_to_the_imagelist_of_big_icons>,<image_index_corresponding_to_the_imagelist_of_small_incons>
*) Columnheaders: At the listview´s property page, in the 'Column Headers' tab, you have a textbox to set the 'Icon Index', wich also corresponds to the index of the image in the actual imagelist.
Was this clear enough?

Hey
I know this has gotta be simple
PrintDocument1.PrinterSettings.PrintToFile = True
PrintDocument1.Print()
I want to either set the file to have it print to, or get the file name that was typed in.
Thanks in advance

All your doing by setting .PrintToFIle to Ture is enabling the little check box on the dialog that allows the user to select printing to a file. The only way your going to be able to get a filename to print to is to build a dialog yourself or use a SaveDialog. Then you'll have to handle outputting the text to the file. You can't "print" to the filename you get.
Unfortunately, the Print To File functionality doesn't work. I'm hoping it'll be fixed in the next service pack for the .NET Framework, if not in .NET 2.0.

You'll have to use WMI and the System.Management namespace to get the all the IP addresses that all the NIC in the machine are using. I can't give you any sample code right now because I just don't have the time.
What was the link to the previous article with the code that you are using?
If you post code, make sure you put it between <pre> and </pre> tags. Also, make sure that you check the little box at the bottom of the message post window that says "Do not treat <'s as HTML tags."
