Hi,
How do I get the installation path that the user selects while installing ?
If I had to copy a specific file from a folder in the local machine under the path where the application is installed , How do I do it ?(for eg : if I have a file named aaaa.dll which is tend to change frequently in the same folder as I have the setup.exe , if the installation path selected is C: and I have created 2 folders bin & data under it using File system editor in setup .How can I copy aaaa.dll to bin & data folder at runtime).
Thankx in advance
Priya

Hi, Priya
You will need to add a custom action to your setup project. Pass the [TARGETDIR] variable to your custom action:
CustomActionData = /instdir=[TARGETDIR]\\
(the last "\\" is neccessary for correct passing of paths)
Get the "instdir" parameter in the custom installer class's Install method in the custom action project:
[code]
Dim instdir As String = Me.Context.Parameters("instdir")
[/code]
That's it

You can interop with the msi.dll COM server to get access to the database and package methods, or you can P/Invoke the exported C-style functions from the same DLL.
You can query the component's installation directory at any time using MsiGetComponentPath, where you pass the ProductCode, the ComponentId, and a path buffer plus it's maximum declared size. See the Windows Installer SDK in MSDN[^] for more details.
There's a catch, though: VS.NET's Windows Installer project sucks. It will generate new ComponentIds each time you recompile and doesn't let you specify a feature/component layout. I'd recommend getting a decent Windows Installer development environment like Wise for Windows Installer[^].
Finally, whether or not that file changes often Windows Installer is designed to allow for such changes and you should not copy the file manually. Windows Installer is an installation package manager - not just a simple install runtime. Just add the changed file to your setup project and make sure that the project's property "RemovePreviousVersions" is set to True and that the "UpgradeCode" never changes. Also change the "Version" according to how much changed (it's really up to you).
If you'd like, you can generate a patch (.msp file) that is the difference between two installation packages. Again, though, because of the Windows Installer's short-comings this would be difficult and would require manual, post-build steps.
This is the correct way to distribute updates to your product.
If you're interested in Windows Installer, see Widnows Installer[^].

More than likely there is a much easier way, but you can always write your own class and inherit it from the DataGridBoolColumn class and you'll be able to handle the checkbox events in that class. As long as you don't change anything else, all other functionality will remain the same. Hope this helps.

The problem is that the DataGridBoolColumn does not use a CheckBox - it's actually drawn using the appropriate state using ControlPaint.DrawCheckBox.

Thanks Heath, I've never actually used the boolcolumn, just assumed it was the same as the textbox column. I'll try not to give bad advice in the future!

A CheckBox is not actually used in a DataGridBoolColumn. The class uses ControlPaint.DrawCheckBox to draw a checkbox in the appropriate state.
A good way is - if you're binding DataSets or DataTables (which actually contain the row data in a DataSet - is to handle the DataTable.RowChanged event. The DataRowChangeEventArgs gives you information about the DataRow that was changed, though not the exact column that was changed. When this event is fired, though, just check the boolean columns in your handler and do whatever action is appropriate.
A more abstract implementation - to handle cases when you bind ADO.NET data sources or typed lists (any IList or IListSource implementation) is to get the CurrencyManager for the control and handle the ItemChanged event:
private void WatchForChanges()
{
CurrencyManager cm = (CurrencyManager)dataGrid1.BindingContext[
dataGrid1.DataSource, dataGrid1.DataMember];
cm.ItemChanged += new ItemChangedEventHandler(
this.CurrencyManager_ItemChanged);
}
private void CurrencyManager_ItemChanged(object sender,
ItemChangedEventArgs e)
{
}

I print 6x4 inch pictures using graphics.DrawImage(),it should work well in most of papersize. But if I select some papersize such as 17x11, 8k and B4,it can't print correct size pictures. I using A4 paper to print and only modify papersize,and I think it should can print size picture. I don't know what's the matter.
thank you.

Use a SqlCommand to execute them, just like you'd type them in a command parser (like the Query Analyzer or osql.exe). Use a SqlConnection that specifies the 'master' database as the 'Initial Catalog', however. The 'master' database must always exist, otherwise you can't do anything, so it's a good database to attach to when running commands like that.
A simple example (without any error checking, like seeing if the files actually exist first):
public void AttachDatabase(string name, string mdfFile, string ldfFile)
{
using (SqlConnection conn = new SqlConnection(
"Data Source=.;Initial Catalog=master;Integrated Security=SSPI"))
{
SqlCommand cmd = conn.CreateCommand();
cmd.CommandText = "exec sp_attach_db @dbname, @filename1, @filename2";
cmd.Parameters.Add("@dbname", SqlDbType.NVarChar, 128).Value = name;
cmd.Parameters.Add("@filename1", SqlDbType.NVarChar, 260).Value = mdfFile;
cmd.Parameters.Add("@filename2", SqlDbType.NVarChar, 260).Value = ldfFile;
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
}
}See the documentation for the sp_attach_db and sp_detach_db stored procs, as well as the SqlCommand.Parameters collection property for more information.

I need to implement a delete FileDialog, which looks exactly like OpenFileDialog, only the button is delete button.
What the easiest way to do that without inventing the wheel all over again.![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)
Best Regards.

There really isn't an easy way, and this will most likely be easiest in a mixed-mode Managed C++ project.
First of all, you need to P/Invoke either the GetOpenFileName or GetSaveFileName APIs, which the OpenFileDialog and SafeFileDialog components already do for you. But you must do it because you must fill-out your own OPENFILENAME struct, which must have certain fields set, as well as the hook procedure (depends on the flags you specify, one of which must be OFN_ENABLEHOOK (32)). You must P/Invoke the SetWindowText and any other APIs (like FindWindow, EnumChildWindows, etc.) to help you find the "OK" button (and for localization, don't assume it always says "OK"). This is so that you can change the caption to "Delete".
You call these from your hook proc you specified in the OPENFILENAME structure when you receive the WM_INITDIALOG (272) message. You also should handle the CDN_FILEOK (-606) message and at that point delete the file.
There's a lot to understand, so I recommend you read about the GetOpenFileName[^] and/or GetSaveFileName[^] (you're modifying the behavior, so it really doesn't matter which you use) in the Platform SDK.

I didn't thought of using managed c++. It's a great idea.
I'll try it.

What is wrong in this code line? (just 1 version of the following 3 used, of course)
m_Data = new Int16[ 36000000 ]; // this functions properly
......... BUT:
m_Data = new Int16[ 37746657 ]; // this results in "System.OutOfMemoryException"
......... AND:
m_Data = new Int16[ 38000000 ]; // this functions properly
So far I found two array size ranges where things go wrong; here are the min/max sizes at the edges of the strange ranges:
37746655 ... 37748726 (0x23ff7df ... 0x23ffff6)
25163743 ... 25165814 (0x17ff7df ... 0x17ffff6)
Please note the similarity of the least 5 digits in the hex representation.
What kind of effect is this?

That is weird, I get the same. Sorry, I am not much help, but when I first saw your post I thought you must have done something wrong but not realised it.
That is very odd.

Hi Everyone!
I was wondering if there is _any_ way to make fance menu images in a context menu. I tried all day long, just to discover http://support.microsoft.com/?id=827043. Unfortunatly they don't tell you about a workaround. Is there really absolutly NO way to make menu images in context menues (apart from dotnetmagic which is no longer free)?
Thanks in advance,
Daniel

Unfortunatly it does not. The Microsoft link I added describes a .net bug that makes it impossible to set OwnerDraw true in ContextMenu instances. The article works fine for main menus, but not for context menues.
Thanks anyway,
Daniel

That is a very specific condition, not even relating to images, but menuitems disappearing from the contextmenu. From your question it appears you have a more general problem. I use my ownerdrawn menuitems interchangebly between a mainmenu and a contextmenu and havent had such problems.
Perhaps describing your problem in more detail would be helpful, then we could help you perhaps, but a bunny rabbit came to me in a dream and tells me you didnt multiply the height of the menuitem with item index, and hence your offsets are wrong in the DrawItem event.

Hi!
Thanks for your anwer. I did something similar like in this article. The comment there points to the MS bug report, hence I thought it might cause the problem.
Here's my MenuItem Subclass. It's based on the Dr. GUI article from here.

}<br />
return s;<br />
}<br />
<br />
<br />
}<br />
}<br />
<br />
I use the contextmenu together with a tray icon. perhaps thats the problem?
