I will explain more about it, I want to write a search engine program that will search input string and matching it with a file in a folder. If matching found, it will show you what file containt that string. The problem is this program can't search a string more than one word so I want to use boolean operator to find a string that we want. For example Google Desktop search engine can search with that operator. Can you help me? If you don't understand about my question you can ask it to me. Sorry for my english.

If you ask the same question so many times, perhaps you should consider that there is something wrong with the way that you write your questions.
:: Use a descriptive subject.
:: Try to explain clearly what you are trying to do.
:: Show what you have tried to accomplish it.

Actually, he has. The problem is he's looking for a "sure-fire" solution to controlling another application using SendKeys...which we all know isn't that reliable to being with. I've already told him a few times to look for alternatives, but it doesn't look like there are any good ones, especially considering his time contraint.

I don't know if this is going to help you, but I have used AutoIt a couple of times to automate other applications (it uses SendKeys() behind the scenes and you still need to build in 'delays').
I have no affiliation with these guys. Just a happy user 
The website is: AutoIt[^]
Anyway FWIW here is the blurb from their website:
AutoIt v3 is a freeware BASIC-like scripting language designed for automating the Windows GUI and general scripting. It uses a combination of simulated keystrokes, mouse movement and window/control manipulation in order to automate tasks in a way not possible or reliable with other languages (e.g. VBScript and SendKeys). AutoIt is also very small, self-contained and will run on 95, 98, ME, NT4, 2000, XP, 2003 out of the box with no annoying "runtimes" required! You can even make compiled executable scripts that can run without AutoIt being installed!
AutoIt was initially designed for PC "roll out" situations to reliably configure thousands of PCs, but with the arrival of v3 it has become a powerful language able to cope with most scripting needs.
AutoIt can:
* Provide a general-purpose scripting language for all Windows versions
* Simulate keystrokes (supports most keyboard layouts)
* Simulate mouse movements and clicks
* Move, resize and manipulate windows
* Interact directly with "controls" on a window (set/get text from edit controls, check boxes and radio buttons, select items in drop-down lists, etc.)
* Create complex user interfaces (GUIs)
* Work with the clipboard to cut/paste text items
* Provide a scriptable RunAs function for Windows 2000/XP/2003
Unlike AutoIt2, the new AutoIt v3 language has a much more standard syntax -similar to VBScript and BASIC - and now supports complex expressions, user functions, looping and everything else that veteran scripters would expect.
As with previous versions, AutoIt has been designed to be as small as possible (~115KB) and stand-alone with no external .dll files or registry entries required. Scripts can also be compiled into stand-alone executables with Aut2Exe.
There will also be updates to the ActiveX and DLL versions of AutoIt called AutoItX - unlike v2 this will be a combined control (COM and standard DLL functions in the same DLL). AutoItX will allow you to add the unique features of AutoIt to your own favourite scripting or programming languages!
Best of all, AutoIt continues to be FREE - but if you want to support the time, money and effort spent on the project and web hosting then you may donate using the link to your left in the menu.

If it's that urgent, ask the people who wrote Crystal Reports.
A 10 second Google search for "crystal reports invalid tlv record" came up with lots of possibilities. This[^] result list even limits the search to BusinessObjects own site, the people who wrote Crystal Reports.

Hi all,
I have a requirement where I need to create a scheduler, which will do
1) Browse and select a DLL (ActiveX DLL) from the file system.
2) Show all the classes from the DLL on a drop down.
3) if we selected a particular class from the drop down then show another drop down with all the public methods in that class
4) If we select a method from the drop down then show all the parameters.
Now allow the user to input the values for the parameters. and set a time a date to run.
All these stuff goes to an XML.
UP TO THIS I HAVE MANAGED TO DO
And the scheduler will read this and run the selected method for the selected class for the selected dll using the given values for the method parameters.
Basically I would like to know how to run a DLL method dynamically from a VB6 code. Remember I am getting DLL name, Class name, Method name, parameters and the respective values from an XML as strings. How we can execute this in VB6? if not possible in VB6, is it possible in VB.NET? how?
Following are the sample code I used to read Tlb stuff from the given dll to form the xml for my scheduler... Please help me thanks!

Dim objtlb As New TLI.TLIApplication
Dim objTlbInf As TLI.TypeLibInfo

Dim tliIrf As TLI.InterfaceInfo
Dim tliMI As TLI.MemberInfo
Dim sDLLFileName As String
Private Sub cmbDLLCoClassesList_Click()
On Error GoTo err:
Set tliApp = New TLI.TLIApplication

Do all your dll's implement an interface? I am not sure a way of doing this in VB 6.0
In VB.NET you can use reflection.

Thanks. I found how to do this. we can use the "CallByName" in VB6. the Method Signature is as follows.
-----------------------------------------------------------------------------------------
CallByName(Object as Object,ProcName as String,CallType as VbCallType,Args() as Variant)
where CallType can be
VbLet
VbGet
VbMethod
VbSet

i want to pass the query string in javascript function hen i use the following code :-
Dim popupScript As String = "" + "window.open('popup.aspx?ID=" + id + "', 'CustomPopUp', " + "'width=550, height=550, menubar=no, resizable=no')" + ""
Page.RegisterStartupScript("PopupScript", popupScript)
then it give me the following error:-
ERROR - "Conversion from string "wi" to type 'Double' is not valid."
please give me the solution
|
|
|
|
|
My guess would be that id is declared as a double?
Mike Lasseter

mr_12345 is right. Since you're using the addition operator and you have a number in the expression, you're actually trying to add a string to a Double. Use the string concantenation operator, "&" instead. Better yet, minimize using it as much as possible.
Dim popupScript As String = "<script language='javascript'>window.open('popup.aspx?ID=" & _
id.ToString() & "', 'CustomPopUp', 'width=550, height=550, menubar=no, resizable=no')</script>"

I have created a project in vb.net which contains three forms named Form1,
Form2, Form3. In runtime i will read form name based on customer input from a table. but this is in string format, like strFormToDisplay = "Form2", how can i show this form from this string, form2 is already included in project, but i can't create a form object using this string
can u pls help me

ajo

You have 2 choices:
select case FormToDisplay
case "Form1"
dim form as new Form1
case "Form2"
dim form as new From2
case "Form3"
dim form as new Form3
end case
form.Show
or
Look at using reflection.

Hi there ,
Can anyone tell me what apppath does? Can I give apppath to my database in VB 6.0. If yes, then what will happen if I change my location of the database from one server to another, and what should I do if in future I want to change my path of the database?
Plz help me out.
Thanx & Regards.

AppPath gives you the directory path of your executable.
If using VB6, you can put your connection string in an ini file or the registry. If using .Net then you can put it in the app.config file or the registry. This way you can easily move your database without recompiling your code.

Hi,
Sorry but I don't know ur name. First I would like to thank u for ur quik response.But I would b requiring some more help.Plz help.
I would like to know in wich ini file should I save the database path,Will I need to give additional attributes of the database like USERID,PASSWORD,LOCKTYPE in that file, and How should I execute that file from the application?
Thanx & Regards.
Success is not a Destination,

You can create your own ini file. Example appliationName.ini. I would place this file in the same directory as your executable.
As far as placing the user name and password in this file, I don't recommend it (unless you perform some kind of encryption on the password).
Are you using one user id to connect to your database or will everyone that logs in have a different user name and password? What kind of database are you trying to connect to?
As for reading and writing to an ini file look at the following link or do a search on google
