Third-class call MyType and returns a variable of type MyNum. Each class will be set to a constructor function and virtual function called Show. The constructor function of MyType receive a MyNum variable, whereas the function Show of MyType will run the Show function of MyNum.
Now, you need set two objects of type MyType and initialize them. Once an object type MyNum and once an object of type MyString.</p>

54,705 | 54,706 | Approach for parsing file and creating dynamic data structure for use by another program | <p>All,</p>
<p>Background: I have a customer who has some build scripts for their datacenter based on python that I've inherited. I did not work on the original design so I'm sort of limited to some degree on what I can and can't change. That said, my customer has a properties file that they use in their datacenter. Some of the values are used to build their servers and unfortunately they have other applications that also use these values so I cannot change them to make it easier for me. </p>
<p>What I want to do is make the scripts more dynamic to distribute more hosts so that I don't have to keep updating the scripts in the future and can just add more hosts to the property file. Unfortunately I can't change the current property file and have to work with it. </p>
<p>The property file looks something like this:</p>
<pre><code>projectName.ClusterNameServer1.sslport=443
projectName.ClusterNameServer1.port=80
projectName.ClusterNameServer1.host=myHostA
projectName.ClusterNameServer2.sslport=443
projectName.ClusterNameServer2.port=80
projectName.ClusterNameServer2.host=myHostB
</code></pre>
<p>In their deployment scripts they basically have alot of <code>if projectName.ClusterNameServerX</code> where X is some number of entries defined and then <code>do something</code>, e.g.: </p>
<pre><code>if projectName.ClusterNameServer1.host != "" do X
if projectName.ClusterNameServer2.host != "" do X
if projectName.ClusterNameServer3.host != "" do X
</code></pre>
<p>Then when they add another host (say Serve4) they've added another if statement. </p>
<p>Question: What I would like to do is make the scripts more dynamic and parse the properties file and put what I need into some data structure to pass to the deployment scripts and then just iterate over the structure and do my deployment that way so I don't have to constantly add a bunch of if some host# do something. I'm just curious to feed some suggestions as to what others would do to parse the file and what sort of data structure would they use and how they would group things together by ClusterNameServer# or something else. </p>
<p>Thanks</p>

<p>I can't figure out how to determine what size bitmap to use. I know how to get the width and height of a View, but not the whole screen. Is there a way to get the screen resolution?</p>
<p>All so I know how to set the bitmap property of a <code>ImageView</code>, but I could not find anything for scaling. Is there a way to scale it, or will I need a separate bitmap for different screen sizes?</p>
<p>This seems like it should be simple, but turning into something very complicated,</p>
<p>Is there a way to get the screen resolution?
Can I scale the bitmap a <code>ImageView</code> displays?
Is there a more easy way to do this?</p>

5,224,450 | 5,224,451 | problem binding to filtered dataview | <p>I'm having a problem with the dtaview. I'm dynamically creating new datacolumns, assigning them values, and adding them into my datatable. Before using a filter, this was fine when binding. All values appeared. </p>
<p>However, I have since chosen to reduce returned results by filtering (by letter), and my returned dataview doesn't seem to allow binding with the newly created data columns. I've mined into the filtered view, and can see that the values are present that I need. </p>
<p>I'm trying to avoid putting everything back into a table again after applying the filter. An sql query based on letter is out of the question, as the whole original table is sitting in view state.</p>
<p>Here are some code snippets:</p>
<pre><code> --Firstly create new datacolumn
Dim ICount As System.Data.DataColumn = New System.Data.DataColumn
ICount.DataType = System.Type.GetType("System.String")
ICount.AllowDBNull = True
ICount.ColumnName = "ICount"
register.Columns.Add(ICount)
--integer value is first calculated and then put into the datatable row
row("ICount") = IntegerCount.ToString()
--filtered view is created from datatable (returned from viewstate)
Dim filteredView As New Data.DataView(pTable, FilterExpression, "Surname", Data.DataViewRowState.OriginalRows)
--view is bound
grd.DataSource = filteredView
grd.DataBind()
--Markup
<asp:TemplateField HeaderText ="ICount" SortExpression="ICount">
<ItemTemplate>
<asp:Label ID="IC" runat="server" Text='<%# Bind("ICount") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</code></pre>
<p>All of the non dynamic datacolumns are fine. Mining into both the datatable and the filtered view show values are there.</p>
<p>Any help would be much appreciated!!!</p>
