What abt the tools available for designing toolbar, but thr a all payed...
|
|
|
|
|
I assume the English translation is 'there are commercial tools for designing toolbars, but I want a free one'.
I have no idea what tools you mean - VS.NET will show your controls as they are, you may be thinking of commercial libraries to offer UI components that are not standard ( i.e. make your app look like Office or Visual Studio ), there are free components on this very site, but the commercial ones are obviously more extensive and better supported.

Yes. If you want something more fancy, or more focused on what you need, you will have to pay for it. Especially in VB, VB has always existed more on the basis of buying components to make it do stuff, than that of coders sharing their work.

Do you want the keypress event in an application, or to write a global keyboard hook ?

Hiya all, I'm unsure whether to place the question here or in asp.net, but opted for here seeing as I use VB.Net as codebehind.
I'm trying to meassure how long time two differnet segments of code uses to excute, approximately - it is only for comparing and personal interest.
However - I end up with results which I just can't seem to accept as being correct.
What I do is use "ticks" at start and end and subtract the two, thinking this would give me the time in ticks between the two... like this:
dim longStart, longEnd as long
dim doubleDiff as double
doubleDiff = 0
longStart = DateTime.Now.Ticks
For intCounter As Integer = 0 To 24999
Next
longEnd = DateTime.Now.Ticks
doubleDiff = longEnd - longStart
doubleDiff = doubleDiff / TimeSpan.TicksPerMillisecond
longStart = DateTime.Now.Ticks
For intCounter As Integer = 0 To 24999
Next
longEnd = DateTime.Now.Ticks
doubleDiff = longEnd - longStart
doubleDiff = doubleDiff / TimeSpan.TicksPerMillisecond
However - this presents me with some odd result. Sometimes the former code segment displays as 0. Sometimes the second codesegment presents as one number and sometimes as that number plus what the first codesegment has displayed as.
So if I for instance get 15.12 as result for segment one, then I will often get X or X+15.12 for the second segment on subsequent runs. X often also is the result of first segment of code multipled with 10 which leads me for sure to belive something is going on which shouldn't be.
I am doing something terrible wrong, but I don't know what - it should be pretty straight forward...
Anybody got some advice for me, or can smack me on the head so I find out what is wrong

If you read the documentation for DateTime.Now(), you'll find that the accuracy and resolution of the clock is very dependant on the hardware clock and only to about 10 milliseonds. Since your results are coming in very close to the clocks resolution, it is very possible to get calculated results of 0 milliseconds, even while using the Ticks counter.
The number of Ticks per Millisecond is constant at 10,000 to 1. But, there is no way in hell that DateTime.Now() will ever return a Tick count that accurately.
If you want to more accurately time something that can execute quicker than about 20 milliseconds, you'll have to use a high-resolution timer library. The .NET Framework doesn't come with one, well, 2.0 does anyway. This library, or class, will have to use the Win32 functions QueryPerformanceCounter and QueryPerformanceFrequency to get sub-millisecond accuracy. You can find an example of writing a wrapper class for these functions here[^] on MSDN. It's written in C#, but is easily converted to VB.NET if need be. There's even a few articles here on CodeProject. Just search the articles for "QueryPerformanceCounter".

And people in Hell want ice water. I seriously doubt VB can do anything about users' mouth's and ear's.

In both a domain environment and Active Directory, this is not possible to do since concurrent logins are not tracked by either service. In AD, the Last-Logon and Last-Logoff attributes are not replicated between domain controllers, so in order to use this information to check to see if the previous user instance logged out before the current one logged in, you'll have to discover and poll all the domain controllers involved with teh domain this user is logging into.
On top of that, in order to control login, you'll actually have to write a new GINA.DLL and deploy it to all the workstations in your domain. This is something that is just not done in VB or VB.NET.

You really didn't read my post did you?
YOU CAN'T DO THIS! The information required to be able to track concurrent connections in AD just doesn't exist!

I have seen a few posts about getting outlook's calendar information aka appointment items. Here is a quick way of getting the information
Imports Microsoft.Office.Core
Imports Outlook
Function Test()
Dim myOlApp = CreateObject("Outlook.Application")
Dim myNameSpace = myOlApp.GetNameSpace("MAPI")
Dim myCalendar = myNameSpace.GetDefaultFolder(OlDefaultFolders.olFolderCalendar)
Dim myItems = myCalendar.Items
Dim apptItem As AppointmentItem
For Each apptItem In myItems
If apptItem.Start >= Date.Today Then
Debug.WriteLine(apptItem.Subject & " : " & apptItem.Start)
End If
Next
End Function

Hi ,
I want to compare the text of two html pages and then highlight the changed text.Do you have any idea on how to do this
|
|
|
|
|
Are the pages similar ? That is, do they have the same layout except for the text ? Perhaps you can just load one, then compare the two as strings, and do an insert where text is different to make a new composite document ?
Is it XHTML ? If it is, then you can do it by comparing XML nodes, and building a new document that highlights in one colour for stuff only in the first document, and another for stuff only in the second.
The XML way is definately cleaner, if it's possible.

actually I need to check a two versions of the same page but if I compared the two versions as text I will not get an accurate result for instance maybe a picture has been changed and even the font size might change I just want to highlight the changed text
|
|
|
|
|
Then, is it XHTML ? Can you make it XHTML ? XHTML is HTML that is valid XML, it means you could load it into an XML document and compare it as XML.

Thank you for your response.
actually the page is a regular html page .DO you have any suggestions on how to highlight the changed text only.

Can you convert it to XHTML ? All you need to do is make sure that the nodes match ( which they probably do ) and turn tags like <br&gr; into <br/&gr;. Otherwise, you're going to be parsing the nodes as well as the text.

I am creating an image map and want to fire an onclick event instead of jumping to another page. What is the best way to do this using VB.Net?
Thanks for any help!

I'm under the impression that the control to do this is new in ASP.NET 2.0.

It is but it is a timing thing! The 2.0 release is still in beta, and my hosting service will not load 2.0 until it is released and even then probably not for a couple of months.
Cheers:
Steve

Web hosts are allowed to host the beta 2, they just have to sign a guarentee that they'll upgrade to the full version on release.
It's possible that you can hack something in 1.1, but I wouldn't recommend it.
