The link I gave you is to the same InnoSetup that I've used successfully in the past. It definately does accept exe files.
An alternative would be to write your own installer, failing that try this[^] and you'll find this[^].

Hi all
I want to call one Windows Application developed in VB.NET from windows service.That should display like pop-up windows application whenever i start the service manually .What method i have to use.
I tried like this but i not get solution :
First i created the one simple windows form application using vb.net available in one specific path.
After that I created the service using vb.net and installed and started.
I want to display that application when i start the service from start event.
This coding i did in the service start event
Method 1:
Dim startInfo As System.Diagnostics.ProcessStartInfo
Dim pStart As New System.Diagnostics.Process
startInfo = New System.Diagnostics.ProcessStartInfo("C:\file.exe") //C:\file.exe is developed windows applicaton
pStart.StartInfo = startInfo
pStart.Start()
pStart.WaitForExit() 'Your code will halt until the exe file has executed.
Method 2 :
System.Diagnostics.ProcessStartInfo("C:\file.exe")
Method 3:
Shell("C:\file.exe");
In method 1 & 2 application started as process. not displaying the application. i want to diplay the applicaion.
Please help any one of you faced like this problem

Didn't this throw you a compile error?
I think what you're actually looking for is System.Diagnostics.Process.Start("C:\File.exe")

This is because Services run under their own desktop, that you can't see. Go into the Services manager, find your service and get Properties on it. Click the LogOn tab, then make sure the "Allow service to interact with the desktop" checkbox is checked.

Subject says it all, I'm looking for something that I can easily use to reproduce as closely as possible the control used in the firefox downloads window. I figured it'd make a great layout for a window for handling file transfers in an application. Does something like this already exist, or at least something close to it?

Hello, I do appologise for the length of this question, but I cannot explain with providing documentation.
For days now I have been trying to write a COM component in VB VS 2005, I have discovered the world of interop amongst things. The application I am working with can call external COM or DLL module which is what I am trying to create (see below for "Documenation".)
My Code / process
New Project, Class -> Add item COM component -> add function
/* simplified calling the function should return what it is passed
Public Function test(byval hello as string) as string
return hello
end function
Create a key using sn.exe, modify assembly file, build project. Copy files onto application server, run regasm /tlb:*.tlb *.dll -> run gac util /i *.dll both return successful. Using oleviewer I can see my class and the method / function. When I test with the application it returns negative. Although I have tried a 100 things this question is already too long
Using VB6 I can add a reference to my module and call the function OK.
Documentation
When a DLL or COM custom function is called, it is passed a configured subset of the current contact data as a character string. Similarly, the custom function is expected to return a set of updates to the contact data as a character string. The following topics provide direction on working with the contact data programmatically.
● Datatype and declaration
● Contact data string layout
Type Sample declaration
COM HRESULT = CustomFunction(BSTR bstrInput, BSTR bstrOutput )
DLL long = CustomFunction( char * pInput, char * pOutput )
B.1.1 Datatype and declaration
Parameters storing the contact data input and output parameters must be declared as single byte character strings in DLLs and as BSTR (wide) character strings in COM modules. Table B-1 shows sample declarations:
The type of character data that may be stored and passed in both the input and the output parameters is restricted to ISO-8859-1 compatible characters.
● When the interface type is a DLL component, the characters must be ISO-8859-1 single byte characters.
● When the interface type is a COM component, the parameter contents must be encoded as UNICODE codepage 28591 (ISO 8859-1 Latin 1).
B.1.2 Contact data string layout
Contact data is passed to and returned from custom functions in character strings. The first two characters in the string store the number of key/value pairs and each subsequent block of 160 characters stores a key/value pair. Up to 99 key/value pairs can be passed into and returned
from the custom function. Within each record, the first 32 characters are reserved for the contact data key and the remaining 128 characters are reserved for the contact data value. Unused bytes within these key and value string fields must be padded with NULL values (binary zero).
For example, Figure B-1 shows the layout of the character string used to pass the following contact key/value pair into a custom function:
● Key: PIN, Value: 1234
Figure B-1Character string layout for contact data passed to a custom function The output string passed back to HPPC from the custom function would be formatted using the same rules. The number of key/value pairs passed within the input parameter and the output parameter may differ. Figure B-2 shows the layout of a character string used to return contact
data from a custom function. The contact data from Figure B-1 has been updated to include an address, possibly obtained by a database lookup.
● Key: PIN, Value: 1234
● Key: Address, Value: 2211 High Street
Figure B-2Character string layout for a contact data returned from a custom function
B.2 Runtime restrictions
When creating custom functions, you should account for the following runtime issues:
● Execution time restriction
● Exceptions
B.2.1 Execution time restriction
When called, the COM module or DLL function must finish execution within five seconds.
B.3 Sample DLL source code
The following is an example of the source code for a custom function called within a DLL.
CustomFunctionExampleDLL.cpp : Defines the entry point for the DLL application.
//
#include <stdlib.h>
#include "stdafx.h"
BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
return TRUE;
}
extern "C"
{
__declspec(dllexport) long CustomFunctionExample(const char * dataIn, char *
dataOut)
{
// Determine number of input parameters
char numParametersAsString[3] = {dataIn[0], dataIn[1], '\0'};
const unsigned int numParameters = atoi(numParametersAsString);
const unsigned int HEADER_SIZE = 2;
const unsigned int KEY_SIZE = 32;
const unsigned int VALUE_SIZE = 128;
// Read each input parameter
for (unsigned int i = 0; i < numParameters; i++)
{
char key[KEY_SIZE] = {0};
char value[VALUE_SIZE] = {0};
const unsigned int keyIndex = HEADER_SIZE + numParameters * (KEY_SIZE
+ VALUE_SIZE);
const unsigned int valueIndex = keyIndex + KEY_SIZE;
memcpy(key, dataIn + keyIndex, sizeof(key));
memcpy(value, dataIn + valueIndex, sizeof(value));
}
// Return a single output parameter
dataOut[0] = '0';
dataOut[1] = '1';
char outputKey[KEY_SIZE] = {'O', 'U', 'T', '_', 'K', 'E', 'Y', '\0'};
char outputValue[VALUE_SIZE] = {'O', 'U', 'T', '_', 'V', 'A', 'L', 'U',
'E','\0'};
memcpy(dataOut + HEADER_SIZE, outputKey, sizeof(outputKey));
memcpy(dataOut + HEADER_SIZE + KEY_SIZE, outputValue,
sizeof(outputValue));
return 0;
}
}
B.4 Testing your custom function
After writing and compiling your custom function DLL or COM Module function, when
configuring the Custom Function component that calls your custom function, you can test
whether your function can be located and loaded properly. Clicking the Test button on the
General tab of a Custom Function component dialog box, will initiate loading of the function
specified in the Interface type, Function name, and Module location boxes. This test does
not execute the DLL or COM Module function.

Did you add a reference to it in .NET? I'm pretty sure you would have and my apologies if the question is condescending but I had to ask.
If I understand your problem correctly, you are compiling a class to expose to COM in order to share amongst assemblies but the COM component your creating isn't returning the results you were expecting?

Thanks for your reply. I contacted the vendor only to find out they require CLSID in order to call the component. My code was indeed correct all along. I do intend posting an article on this topic.

Hello... is it possible to have justify alignment in a multiline textbox?
i want to make a movie database and i have a textbox that shows the plot and i'd like to have it with justify alignment. is any other way except using a textbox to present the plot?
thank you in advance

I don't believe a textbox supports this, no.
You should only use a textbox or rich textbox if you want the text to be editable. Otherwise, use a label.

Yep. He's right.

but again label doesnt support wrap word with justify alignment... it is the same with textbox.. only difference it supports Trasparent...

Hi..
I have made a custom template that derives from ITemplate.
I have also create a class that inherits from INaming container.
For some reason i can not get the INaming container to work with my custom template. In order to implement the INaming container one must have a property that returns an ITemplate.
Why can i not return my custom Template the derives from ITemplate?
here is some of my code:
----
[ParseChildren(true)]
[PersistChildren(false)]
[ToolboxData("<{0}:HoverCalendar runat=server>")]
public class HoverCalendar : WebControl, INamingContainer
{
private ITemplate _itemTemplate;
[PersistenceMode(PersistenceMode.InnerProperty)]
public ITemplate ItemTemplate
{
get { return _itemTemplate; }
set { _itemTemplate = value; }
}
protected override void CreateChildControls()
{
Controls.Clear();
HtmlGenericControl container = new HtmlGenericControl("div");
if (ItemTemplate != null)
{ ItemTemplate.InstantiateIn(container); }
Controls.Add(container);
base.CreateChildControls();
}
}
*** this works fine; however, how do i use my ( the one below for example ) template?
----
public class myItemplate_1 : ITemplate
{
static int itemcount = 0;
ListItemType templateType;
public myItemplate_1(ListItemType type)
{
templateType = type;
}
public void InstantiateIn(System.Web.UI.Control container)
{
Literal lc = new Literal();
switch (templateType)
{
case ListItemType.Header:
lc.Text = "";
break;
case ListItemType.Item:
lc.Text = "";
break;
case ListItemType.AlternatingItem:
lc.Text = "";
break;
case ListItemType.Footer:
lc.Text = "| Items |
|---|
Item number: " + itemcount.ToString() +
" | Item number: " +
itemcount.ToString() + " |
";
break;
}
container.Controls.Add(lc);
itemcount += 1;
}
}
thanks
