u can do it
first strore the values in some global vaiable.
for that u can make a module. therefore that values will be accessible to all forms
then u can use those values in ur datagrid
|

|
|
|
Add new module to the project and there declare public variable (Public Value As Integer). Then You can use this variable in form1 and form2, as well.

you can do one thing
First you declare the friend or public variable in then you cn call us follows
In form1 Write as follows
dim frm as new Form2
frm.Showdialog(Me)
me.DataGrid = frm.PublicVarDataTable
In Form2
Public PublicVarDataTable as datatable
OkBut_Click()
// add rows in table
Me.DialogResult=ok
Me.Hide
End sub
I hope this helps

whasup!
You just need to create properties which will contain the values read from the textbox. After you have those values simply dispose your form2 object.After this you still can access the properties of the object because only the visual were disposed you can retrieve the properties by doing:
myForm2Object.property1
myForm2Object.property2
(...)
myForm2Object = nothing
this way you won't need modules.
Never say never

Hi , please any one can help me how to make an application a service in VB 6 so that when the windows starts that application runs itself any don't have any need to start it.
i.e , it starts itself.
|
|
|
|
|
If you just want the application to runs itself when the windows starts, you don't need to make a window service application.
See this[^]

Do you want to run your app when Windows starts or when the user logs on?
If you want to run it when the user logs on, follow the link the other person posted.
If you want to run it when Windows starts, check here[^]. Warning! You'r application cannot have a user interface! If your app isn't completely autonomous, you'll run into problems with your application, and possible even stop Windows from shutting down! VB6 was not designed to create true, native Windows Services.

can .net exe run on machine where .net Framework is not present. if yes how to make that exe.

No! The machine MUST have the .NET Framework installed.
You COULD get away with using the NGen utility to create a native code version of the application, but it will be VERY processor specific. So you'll need to generate a version of the code for each processor you want to run the code on, such as a version for an AMD Althon XP, another for an Intel P3, another for an Intel P4, ... and so on. There's a little problem with doing this though, NGen will also tweak the code a bit for known problems in certain revisions of each chip.
The easiest way to get around this little issue, is to install the .NET Framework, the same version that the app was developed under, on each machine that is going to run the app.

i want to know how to make the exe that run on all win32 platform as exe present in the release folder of visual c++. how to make that exe in vb and vb.net
ddd

Build it! The resulting .EXE will be in the projcet folder. For a VB6 app, the machine will need the VB6 runtime installed and for a VB.NET app, it will need the same version of the .NET Framework installed that the app was build against. -- No exceptions!

To create a database, use something like this:
CREATE DATABASE Sales
ON
( NAME = Sales_dat,
FILENAME = 'c:\program files\microsoft sql server\mssql\data\saledat.mdf',
SIZE = 10,
MAXSIZE = 50,
FILEGROWTH = 5 )
LOG ON
( NAME = 'Sales_log',
FILENAME = 'c:\program files\microsoft sql server\mssql\data\salelog.ldf',
SIZE = 5MB,
MAXSIZE = 25MB,
FILEGROWTH = 5MB )
To create a table use something like this:
CREATE TABLE publishers
(
pub_id char(4) NOT NULL
CONSTRAINT UPKCL_pubind PRIMARY KEY CLUSTERED,
pub_name varchar(40) NULL,
city varchar(20) NULL,
state char(2) NULL,
country varchar(30) NULL
DEFAULT('USA')
)
To alter a table use something like this:
ALTER TABLE doc_exa ADD column_b VARCHAR(20) NULL
If this is not enough help there are already some great documentation and articles already out there on the internet: CREATE DATABASE[^] CREATE TABLE[^] ALTER TABLE[^]

You can use the following SQL Statement to get the data out of the database that you want:
SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS AS tc
INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE AS kcu
ON tc.CONSTRAINT_CATALOG = kcu.CONSTRAINT_CATALOG
AND tc.CONSTRAINT_SCHEMA = kcu.CONSTRAINT_SCHEMA
AND tc.CONSTRAINT_NAME = kcu.CONSTRAINT_NAME
WHERE tc.CONSTRAINT_TYPE = 'PRIMARY KEY'
AND tc.TABLE_NAME = @TableName If this SQL Statement returns rows then they each represent one of the columns of the primary key (maximum of 16). If it returns no rows then there is no primary key.
Does this help?

Im writing a paint program using GDI and currently im having some difficulties using the opendialog box. Im using it so the user can selec a bmp to use for a texture fill.
The problem is when you click inside the dialog box it will effect the drawing surface beneath it also. This causes the program to crash as it is trying to use a textute brush with no image loaded into it.
Does anyone know a way so dialog boxes dont effect what beneath them?
|
|
|
|
|
It's not supposed to be affecting what's under the dialog box in the first place! How did you show the Dialog?
