C/C++ :: Scan A Directory Recursively
Dec 19, 2014I'm writing a C++ module that is meant to recursively scan a directory and I'm curious what yall think of my strategy.
The program is a music player and so I'm trying to make the directory scanner as lightweight and efficient as I can. I've decided I want to scan the files in two passes- first I just want to get a list of all music files that are found in a directory/subdirectories and then I want to process the list and search for id3s/other tags.
As I'm a scanning the directory, I've decided to store the temporary list in a linked list where each node is containing an array of 100 strings. I did this because I obviously don't know how long the list will be and I from my understanding of the C++ vector class it basically just makes over sized arrays and moves them when it runs out of space. That sounded rather clunky to me, as did a traditional linked list.. I didn't see the point of allocating memory that many times in a row.
C# :: Treeview Node Selection Show First Node Of Tree Instead Of Selected
Apr 22, 2015I am working on C# Project [Windows Form Application], to update treeview nodes from excelsheet [xls] Cell [row i, Column 3] Values, while on selecting treenode, it should update corresponding Column 4 Value [row i, Column 4]. For me, Treenode are populated successfully, but on selecting the treenode, it always display first Element of treenode [Not selected one].
Populated Treenode from Excel as: [ Update Child Nodes from Column 3 elements [Column 2 Contain Parent node name and Column 3 have Child Node name], if Column 2 Value is same as Parent node name [My Module], update the child nodeunder same Parent node.]
for (int i = 0; i < worksheet.UsedRange.Rows.Count; i++) {
string mynode = ((Excel.Range)worksheet.Cells[i + 1, 3]).Value2.ToString();
string mynode2 = ((Excel.Range)worksheet.Cells[i + 1, 2]).Value2.ToString();
[Code] ....
On selecting the Child Node, it always give 1st Parent node. Instead of Selected Node.
for (int i = 0; i < worksheet.UsedRange.Rows.Count - 2; i++) {
string mynodetext = ((Excel.Range)worksheet.Cells[i + 2, 3]).Value2.ToString();
string mynodetext1 = ((Excel.Range)worksheet.Cells[i + 2, 4]).Value2.ToString();
if (treeView1.SelectedNode.FirstNode.Text == mynodetext) {
this.richTextBox1.SelectedText += Environment.NewLine + mynodetext1 + Environment.NewLine;
}
}
How to get correct selected Node.
C++ :: Recursive Directory Scan - Can Use Multi-threading For Speed?
May 11, 2014In our Qt application, we have to load several files on application start-up starting from a root directory.
We are recursively scanning the directories and loading the files.
The total time it takes is about 12 seconds. Can we reduce this time if we use multi-threading?
I have heard that multi-threading does not work everywhere and it increases code complexity and debugging issues.
Would multi-threading solve the above problem? We want it to be platform independent (Mac, Linux, Windows).
C Sharp :: TreeView To Database Or At Least DataTable
Feb 8, 2014The main question how to fully traverse/circumvent through all TreeView, for transforming Tree structure into a Table structure.
I want to note that the TreeView may contain a different number of branches, with different depths and different names.
I found a lot of information how to populate TreeView e.g. from DataTable, but I didn't found information how to recursively traverse/circumvent a TreeView and populate/fill data e.g. to DataTable.
As sample I have following TreeView:
Aaron
-Baldwin
--Caleb
---Dale
--Earl
-Fabian
Gabriel
-Harold
-Ian
Necessary to convert the TreeView into e.g. DataTable:
id | Name | ParentId
--------------------------------
1 | Aaron | null
2 | Baldwin | 1
3 | Caleb | 2
4 | Dale | 3
5 | Earl | 2
6 | Fabian | 1
7 | Gabriel | null
8 | Harold | 7
9 | Ian | 7

C Sharp :: Passing Selected Row From Gridview To Dropdown
May 17, 2013passing selected row in gridview to my dropdown. I have 1 gridview, 1 textbox and 1 dropdown list box. My dropdown is populated by SqlDataSource from my table Country. On my gridview, I have 3 columns, which are SELECT, NAME and COUNTRY. Under SELECT column, I have my hyperlinked Select, every time I clicked on a certain row NAME will pass in textbox (no problem with that), but in my dropdown it does not populates the COUNTRY that I choose. For example, I have Jack for name and USA for country. Beside Jack and USA, I have a hyperlink Select, when I click Select, Jack will display on my textbox and supposed to be USA will display on my dropdown but not displaying instead it says an error "'cboCountry' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value".
I have tried the codes below:
protected void GridView2_SelectedIndexChanged(object sender, EventArgs e)
{
txtname.Text = GridView2.SelectedRow.Cells[1].Text;
cboCountry.Text = GridView2.SelectedRow.Cells[2].Text;
}
Only the textbox os working, no luck at all in dropdown...I'm using c# and asp.net.

C Sharp :: How To Set Rootpath Of Application Which Is Path Of A Selected Item In Listbox
Apr 4, 2013I want to set the rootpath of an executable application. This rootpath should be the same as the path of an item that I select from a ListBox. The code for selecting the item is as follows.
namespace Menu {
public partial class Form1 : Form {
private Button button;
private ListBox listBox1;
private string selecteditem;
[Code] ....
Now what I want is: Whatever I get the output as in the :
Console.Writeline(path + selecteditem),
I would want to set this as a rootpath for an application so as to do rest of the measurements or steps only in that path/folder. Is it possible to do something like this?
C Sharp :: Access Database Is Copying To Output Directory On Its Own
Oct 4, 2014I have an extremely annoying problem, I am inserting data into an access database and now i have noticed that it is copying itself to the bin/debug folder on ts own and yet i have set "Copy to Output Directory" property to "Copy never"
But without fail, it is copied! It is making any attempted updates to the database's information invalid since its not updating at all.
This all started when i installed crystal reports and it asked me to make a duplicate of the database in order to utilize data-sets that were created for certain reports.
Why this is happening? I cannot test my application properly at all.

Jul 14, 2014Right now I'm working on a TreeView for which I would like to add a TextBlock and a ComboBox as child nodes of a Parent TextBlock node. This would look something like this:
My TreeView is implemented using an MVVM style, and utilizes a HierarchicalDataTemplate. I have had no problems with adding TextBlock nodes and TextBlock children, but the confusion seems to arise when adding child nodes of different UI types.
I have tried implementing a stackPanel, like so:
<HierarchicalDataTemplate DataType="{x:Type Data:Node}" ItemsSource="{Binding Teams}">
<StackPanel>
<TextBlock Text="{Binding IndividualProperty}" />
<ComboBox ItemsSource="{Binding CollectionProperty}" />
</StackPanel>
</HierarchicalDataTemplate>
But then I end up with each node looking like this. It's like each node comes with one TextBlock and a ComboBox (Note: The comboBox is not the child, it and the TextBlock are one node):
How do I allow my treeView to have child nodes of different UI types? I am thinking that my solution has to do with my Hierarchical Data Template.
