Hi,
I'm developing a setup project. Can you help me with these queries
- How do I get the installation path the user enters at runtime
- How can I copy some files to specified location eg:C:\temp
- How can I check for existence of a particular folder? Is it possible with Launch Condition. If not how can I do it?
-'User Interface -Add Dialog '- How can I get the values entered in the textboxes at runtime and pass it to my application?
- Custom Action properties , properties- Installer Class - true / false signify ?
- How do I start an application when Installation completes ?
Thankx in advance
Priya

I guess InstallShield for Visual Studio .NET is the tool you need for what you want to do. I usually use that tool to do this kind of tasks

That's actually not necessary. All but the last request can he do with the very limited VS.NET MSI project, and for the cost InstallShield isn't worth it.
I started beta-testing the Windows Installer runtime and Wise for Windows Installer before Windows Installer 1.0 was released. Wise was always much cheaper and up until v4.0 of InstallShield, Wise was the only one that provide access to ALL the MSI tables, as well as giving you the ability to create your own tables (for use with binary custom actions and what-not). The first InstallShield for Windows Installer didn't provide access to tables at all and slowly added support for select tables. For a Windows Installer hack like me, I was rather purturbed and have always stuck to Wise for commercial deployment projects because I continually find myself changing a few things in the tables directly even through WFWI provides ample functionality for doing it automatically (there's just a few things I like to do to personalize the designer, more than not).

Query the [INSTALLDIR] property.

If you mean the temp directory as assigned by the system (it hasn't been C:\TEMP since Windows NT 4.0 and Windows 98, IIRC), then parent your files to the TempFolder directory, which is assigned the correct path based on the user level at runtime.

In Visual Studio .NET, click on the Launch Conditions Editor, right-click on "Search Target Machine", and add a new search for a File. You can specify a folder. See the DrLocator table in the Windows Installer SDK on http://msdn.microsoft.com[^] for more information.

Use the VS.NET form designer for your installer project and enter property names in the property grid. At any time after those properties are set (and if they're not, their value is NULL) you can query them - as with all properties - using [PropertyName]. Make them all upper-case in order to set them from the command line for msiexec.exe.
Dpriya wrote:
Custom Action properties , properties- Installer Class - true / false signify ?
After you add a custom action for an Installer class, you can change the command line to accept swithces. In your Installer class, use the Context.Properties dictionary to get the string values and parse them into whatever values you need. For booleans, use Boolean.Parse or Convert.ToBoolean(string).
Dpriya wrote:

This isn't easy to do with the VS.NET installer project. After the build, you must use a tool like Orca to manually modify the MSI package. You add a custom action to the CustomAction table with a unique string key, custom action type 18, the File table key for the executable you just installed and want to launch, and then any command-line parameters you want to pass to that executable. See the CustomAction table in the Windows Installer SDK for more information.
In order to execute that, go to the InstallUISequence table (if you only want to launch it when a full or partial UI is specified, which is recommended), or the InstallExecuteSequence table. Add the name of your custom action there along with a sequence number that is after the InstallFinalize action (recommended), but set the condition to INSTALLED to only execute that if the MSI package was just installed (as opposed to uninstalled). During installation, NOT INSTALLED evaluates to true until the InstallFinalize action is executed.
For more information about Windows Installer, see the Windows Installer SDK.
If you want a good development environment - much better than VS.NET's installer projects - then get something like Wise for Windows Installer[^] (cheaper, just as capable, and was ahead of InstallShield for many years in terms of functionality) or InstallShield Developer[^] (very expensive, especially for entry-level installer developers).

I agree with Heath, you may use a ready-to-use tool like wise or InstallShield to do deployments. Both tools are good. Personnally, I'm used with InstallShield since version 5 (currently v9 SP1). But don't try to program yourself the Windows Installer Service... Even with the SDK, it's a crazy architecture. The relational database of the Windows Installer service is not easy to understand and it's complexe to fill the tables. You will almost have to write your own programs to fill these tables. It should be easier with an appropriate tool either Wise or InstallShield.
Best regards.

I never really had a hard time understanding it at all. In fact, just the other week I finished doing a large amount of hacking to the generated MSI package for the AutoCAD OEM we've licensed to add a lot of extra files and actions that it didn't know about when building the MSI package from it's own template. I did all this using Orca. I do plan at some point to write a simple script or application to automate this (to avoid stupid mistakes including typos or just forgetting something), but it wasn't hard to do if you understand it.
Windows Installer is a great runtime and I'll never go back to a proprietary installer technology like InstallShield (which I used a little before Windows Installer). The transaction functionality is excellent, and correctly authored MSI packages are great for advertised and administrative installations, something I haven't seen in proprietary installer technologies from the likes of Wise or InstallShield.

For information, know that InstallShield uses MSI packages if you ask for it. if you select an MSI project under InstallShield, it will show you a series of interfaces to help you to fill easily the tables needed to build the MSI/updates package with all actions or dialog boxes you need. 
Both: Wise and InstallShield are good tools, they are just different... like Maya or 3DS... 
Best regards.

I know. They used to have a separate IDE for Windows Installer but recently (last time I checked) bundled it with InstallShield Developer, which is much more expensive and - if all you want is a Windows Installer IDE - isn't worth it.

I writing an N-tier application, where I will used strongly typed DataSets as data transport objects between some tiers.
The application consumes a web service. By default VS has created a proxy and a number of classes that are used to hold the data the web service returns, ie classes that mirrors the result xml structure. I want to move to DataSets instead.
Is there a clever way to make a web service proxy automatically fill a typed DataSet instead of the auto-created classes when I call the web service? Observe that this web service does not return a DataSet per se (this would be simple then), but a structure that would easily be held within a DataSet.
Manually I can look inside the wsdl, extract the schemas, let VS create typed DataSets from those schemas, write code that consumes the web service through the proxy, move over all retrieved data to my DataSets, done. Since this seems like a common scenario, I'm just hoping that VS has an automated way of doing this. What would be the easiest way?
Kind regards,

Does the Web Services return a typed DataSet? IIRC, if it does the generated proxy should create a typed DataSet as well. I could be wrong - it's been a while since I consumed a Web Services (I have - a lot - it's just that now the clients already have the proxies and I haven't had a need/desire to consume another WS lately).
If not, you can always write your own proxy - it's really not that hard - so that it uses a typed DataSet. Just look at the source for the generated proxy and you'll see how easy it is to create your own, pretty much as you suggested you might do. I'm not aware of any automated method that VS.NET provides, since it's only automated method of generating a proxy us what you've already used (similar to wsdl.exe, if it doesn't actually use it already).

Thanks for the reply Heath.
If the web service returns typed DataSets, then the proxy will return untyped (regular) DataSets, but the content can easily be moved to a typed DataSet by use of the DataSet.Merge method. But my problem is that the web service does not return a DataSet, even though the actual xml structure is very similar. I'm curious why I havn't found anything fruitful Googling around for this. What would be a really good setting for the proxy generation would be a checkbox: "return as [] DataSet or [] object hierarchy classes".
I have some ideas I will try shortly:
- Getting hold of the web service reply in original xml format, and deserializing it into the typed DataSet. Weakness: Probably requires some tweaking of the xml.
- Manipulating the wsdl so that VS thinks that DataSets are returned, and creates the proxy to return DataSets. I have my doubts that this will work automatically.
- Writing a generic method that by use of reflection can move an object hierarchy into a typed DataSet. Ugly.
Writing my own proxy might be a good alternative, thanks for the tip. It probably can be very generic too (or based on a very generic base class), so it can be used for all "web service reply -> typed DataSet" scenarios.

If the XML returned for the DataSet is in the correct format (which is should be, since DataSet are marshaled as XML even for the BinaryFormatter provided in the FCL), you can always use DataSet.ReadXml to read it into a DataSet.
I'd have to agree with you as well that modifying the WSDL would probably not yield the result you're looking for.

Sorry, you were right, VS creates a strongly typed DataSet for the proxy, not a regular DataSet as I wrote.
It would be interesting to find out how the SoapHttpClientProtocol.Invoke method finds out what classes to use when it deserializes the incoming web service response. My guess is that it uses reflection to search the current assembly and current namespace for class names that simply matches the xml-tags in the response. Would be glad if anyone had any input on this.
What still puzzles me is this: I can find numerous examples that show how easy it is to pass a typed DataSet from a web service to a web service consumer, as long as you use VS to create both ends. Very neat, VS creates all code for you. But isn't web services about platform independence? So when a Java web service exposes data in a DataSet-similar format (which by the way could be just any format, the DS is very flexible), VS wont help me with code to fill a typed DataSet? I have write a lot of plumbing code. Sure, I can take the object hierarchy, serialize it into xml, and read the xml into the DataSet, but that isn't a very optimised way of doing things.

VS.NET knows nothing more than what the WSDL tells it, so even if you exposed an XML Web Service created in Java, a DataSet-like schema should still create a typed DataSet. Even if it doesn't, nothing is stopping you from created a typed DataSet as we discussed before.
If you're interested in how the classes work, I suggest you learn how to at least read MSIL (Microsoft Intermediate Language, extensions to Common IL) and use ildasm.exe from the SDK to examine the classes, or use a decent decompiler like .NET Reflector[^], although sometimes it can't properly decompile the IL so you have to resort to reading IL in those cases, anyway. It's how I learned so much about the internal workings, and can provide insight into better ways of coding your classes by seeing how Microsoft does things, as well as designing your classes to better utilize the FCL knowing how things work internally.

hai there,
i am an middle level c# Programmer. in my current project i want to know all ip address of machines that are connected in my local network.

Hi!
I have a piece of code that maybe helps.
<br />
try<br />
{<br />
System.Net.Dns.GetHostByAddress(serverAddress);<br />
}<br />
catch (System.Net.Sockets.SocketException)<br />
{<br />
}<br />
The exception is thrown, when no computer with the specified address is reachable. The serverAddress can either be a string specifing an IP-address or an object of IPAddress class. See documentation for further information.
Maybe you could build a loop and process this test for every address possible in your local network. This may be not very efficient, but at least it's better than nothing

thanks for DrGreen (pedrosferreira@hotmail.com) 's suggestion first.
then here is my question:
i get many small bitmap parts from a large bitmap and turn them into stream which can be sent through socket. of course every part has its original coordinary(x,y), so i can restore the original large bitmap correctly .
now ,i need to draw the the recived image parts to a bitmap in memory .
How to write the code ?
please show me the way.
|
|
|
|
|
In this example dest is the destination bitmap and SourceBmp is the source bitmap, I've used x and y loops to simulate putting many smaller (48x48 pixedl) bitmaps into one large (192x192 pixel) bitmap.
Bitmap dest = new Bitmap(48*4, 48*4);
Graphics g = Graphics.FromImage(dest);
for(int x = 0; x<4; x++)
{
for(int y = 0; y<4; y++)
{
g.DrawImage(SourceBmp,x*48,y*48,48,48);
}
}
Does this help?

I Have a class that inherits from the Frameworks DataTable, and i wish to serialize it.
I added the Serializable attribute to the class but when i deserialized i got an exception that said that i needed a constructor that could create the instance by deserialization. Then i noticed that the private members of my class were not serialized since the DataTable class implements ISerializable, so i need to override the GetObjectData method, but it is somehow defined as private in the DataTable class (According to the Reflector).
 If anyone encountered a problem like this and knows the solution i would appreciate it.
I Tried it with the HashTable class and didn't have any problems, this is only with the DataTable class.

GetObjectData is an exlicit interface implementation. Depending on what you add to your derivative DataTable class, you probably don't need to override this anyway. To define the constructor, create a constructor for your class (any access modifier will work since reflection is used to invoke it) that follows the following pattern/example:
protected MyDataTable(SerializationInfo info, StreamingContext context) {}
You should also look into typed DataSet. These can easily be created in VS.NET (add a new DataSet item to your project from Add-<Add New Item). This is an easy way to create a typed DataSet with typed DataTables and DataRows (actually, the columns themselves) that are faster when accessing data by their column name and use the default serialization provided by the DataSet and DataTable to serialize your typed DataSet correctly.

My problem is not with the deserialization, it is with the serialization it self.
My private members are not serialized so thats why i want to use the GetObjectData method, but when i use it i cannot call the base class's method since it is private and there for i can either serialize my members, or my bases members but not both.
I cannot use a DataSet because it will cause too many changes in my code.
I would appreciate any help on this matter.

You can call it. Like I said, it's an explicit interface implementation, which means you must cast the base to the interface in order to call it like so:
((ISerializable)base).GetDataObject(info, context); (where info and context are your parameters for your implementation of GetDataObject).

The compiler does not permit this call, it said that :
'the keyword base is not allowed in this context'
|
|
|
|

So it does. Guess you'll have to refactor your code, then.
