First just try opening Query Analyzer and try something like this but replace "value" with something real.
Select * FROM EmpMaster1 WHERE EmployeeName LIKE '%value%' and if that works just translate it into something you can put into the code. Do the same for the number filter but you will probably need to do the cast to varchar in order for it to match if it is stored in the database as a number.

Why the bold font ?

you can't. A dialog box has nothing to do with it. You need to use the Office toolkit to talk to Excel, and it works the same, no matter what the UI.
chaiotali wrote: How can get sql database n tables in to combobox or listbox
You can do a select to get a list of the tables, then you can make that the datasource of your control
chaiotali wrote: How can we refresh datagrid when we add new record in to database
You can't, really, your database cannot send messages to your app.

What linked list are you using ? Isn't there an InsertAt method ?

This is actually a VB6 question. I'm trying to set up a VB DLL so that if it can't instantiate an external COM object because it is not registered properly it would run regsvr32.exe against the DLL to register the object and then try to instantiate it again. I'm using CreateProcess to run regsvr32 against the DLL and the problem I'm running into is that when the CreateProcess method is invoked, regsvr32 generates a dialog box indicating that LoadLibrary can't find the specified module. The module it prints out is the correct path to the DLL. Does anyone know how I can get this working?
|

I'm not sure, but it sounds like you're passing in a path to the .DLL that includes spaces. You'll have to enclose the path in double quote marks so the command line you pass to CreateProcess looks more like this:
REGSVR32 "C:\Program Files\Folder\Some Folder\MYDLL.DLL"
If not, RegSvr32 will look for a file called "Program" at the root of C:, not MYDLL.DLL in the path you want.
To build the path string with quote marks inside it, you have to use 2 quotes to get 1:
Dim path As String = """C:\Program Files\Folder...MYDLL.DLL"""

I am but I am enclosing the path in double-quotes. I found this out the first time I tried it without double-quotes. Regsvr32 complained about not being able to find the C:\Program component.
What I found was that I could set up an console app built in Visual C++ to do this and it worked fine if I ran it from the command line. But if I called the Visual C++ executable from my VB app, it gave me the same error. It looks like it has something to do with trying to run regsvr32.exe from a VB instantiated thread.

I never had a problem running RegSvr32 from VB6 or VB.NET. Since a process gets it's own seperate thread, regardless of which thread you create it from in your app, I don't see how this would cause a problem. Hmmm... Are you running multiple copies of RegSvr32 at the same time? (grasping at straws here...)

I'm just setting up the command line in a string and passing the string to CreateProcess like this:
Dim cmdLine as String
cmdLine = "regsvr32.exe " & Chr(34) & "C:\Program Files\ProgramFilesFolder\DllFilename.dll")
I'm passing a NULL string for the application name, a NULL for the process attributes and thread attributes, not inheriting the handles, NORMAL_PRIORITY_CLASS for the priority class, NULL for the environment pointer and current directory, and pointers to a startup info and process info structure with just the sizes set in both. Should any of these parameters on the CreateProcess call be set differently?
|
|
|
|
|
Sorry. In the previous example I should have added the trailing Chr(34) for the ending set of double-quotes instead of the end paren.

I'm not running multiple copies of regsvr32 that I'm aware of. The only thing I can think of that would cause problems is that the process that I'm invoking regsvr32 from doesn't have admin privileges. However, I can set up a test app using VB and run it from an account that I know have admin privileges and I get the same results. If I set up a Visual C++ app that does the same exact thing as the VB test app, it works perfectly.

As an alternative to regsvr32, you could (pinvoke) call the DllRegisterServer function in the Dll. Regsvr32 executes this function in the Dll to perform the registration.

Hey
I have inherits the Textbox-control but i'm
having problem with my properties that i have added.
this is the class with the property added:
Public Class TPTextBox
Inherits System.Windows.Forms.TextBox
private _blndirtyEnabled as boolean
Public property DirtyEnabled as boolean
set (byval value as boolean)
_blndirtyEnabled = value
end set
Get
return _blnDirtyEnabled
Get
end property
end class
now i want to edit the value through the "properties"-window in designmode to "true"
but it always returns to "false" when i try to save the Form that i have dragged the control to.
in the designer file the form has put this line:
me.TextBox1.DirtyEnabled = false
i want it to store the value that i have changed it to but it always return to "false".
i have removed the line but it wont work.
whats is wrong
|
|
|
|
|
Odd, I tried it and didn't have any trouble. Did you try changing that line so it sets the property to true, instead of just removing it. Also you might want to try using the control in a new project to see if the problem persists.
|
|
|
|
|
<defaultvalue(gettype(boolean), "true"),="" category("appearance"),="" description("")=""> _
Public Property DirtyEnabled() As Boolean Implements Interfaces.IDirtyTracking.DirtyEnabled
Get
Return _blnDirtyEnabled
End Get
Set(ByVal value As Boolean)
_blnDirtyEnabled = value
End Set
End Property
i forgott to mention that i have this above the "property"
<defaultvalue(gettype(boolean), "true"),="" category("appearance"),="" description("")=""> _
when i removed it it worked fine.

A user fills out info on a TabPage in a TabControl. When the user clicks on another TabPage I want to validate the information before switch to the new TabPage. So far I'm using the Leave event to validate the info but if there is a problem I want it to stay on that TabPage. How can I prevent it from switching to a new TabPage if needed?
|
|
|
|
|
can't you disable all other tab pages until they have saved?

Can someone please help me about how to read multiple .doc files, say 40 word files into an array of String

I have the following code in a DLL, and it must be called from a VB6 application.
That's the code:
#######################################
#include
struct tpteste
{
int i;
};
void __stdcall test( tpteste **l )
{
tpteste *t = new tpteste[4];
t[0].i = 99;
t[1].i = 98;
t[2].i = 97;
t[3].i = 96;
*l = t;
}
void __stdcall doNothing( void )
{
tpteste *w = NULL;
test(&w);
}
#######################################
I need to discover how to call the test function from VB passing a pointer-to-pointer (or any workaround).
If someone can help... thanks in advance.

VB6 doesn't support pointers, so I fail to see how a poiinter-to-a-pointer is going to work. VB can pass in parameters ByRef, which is a pointer to an object or value, but that's about as far as it's going to go.
