VB6 is an old language which has nothing to do with .NET (i.e., a VB6 executable has a PE Header but no CLR header). What happens when you click an executable compiled from VB6 is that the assembler code produced by the compilation process is simply executed.

I would not spend too much time on VB6, though, as it is quite outdated nowadays.

thanks for your another reply sir.
hence my knowledge is low so i am curious to know the inner story of various tool and technology like how they run. java application has any PE header ?
thanks for your time sir. good day 
|
|

|

ALL .EXE's have the PE header that tells the Windows Loader how to load the executable. It doesn't matter what runtimes the .EXE runs under.

Morning, thanks a lot for reply.
i am not java guy but i heard java do not come with exe file....so what happen in case of java apps when it run on windows OS?
i heard java has .jar file which is self executable....so jar has PE header?
C and C++ generate exe file when compile....so C and C++ generated exe file has PE header?
please share the knowledge. thanks

JAR files are not executable. They are just a bunch of data that Java interprets as code, referred to as "bytecode". Java is a virtual machine environment with its own instruction set. This bytecode isn't run natively by your CPU like .EXE executables.
You apparently don't know how file associations work. Ever double-click a .TXT file or a Word file? You're actually launching the executable associated with that file extension.
For .txt files, the command line launched is
%SystemRoot%\system32\notepad.exe %1
where the %1 is replaced by the full path to the .txt file you double-clicked.
For .jar files, it's no different. The command line launched is something like this:
"C:\Program Files (x86)\Java\jre1.8.0_102\bin\javaw.exe" -jar "%1" %*
Again, the %1 is replaced by the full path to the .jar file.

Hi,
I have a view which has two list boxes, one on left contains all the selection, two buttons to "add or remove" selection and one more listbox on right which contains selected values.
I am able to get the list of selected values, but what I would like is the list of unselected values on posting. The object in the model is null for the list of unselected values.
How can pass the list of unselected values?
Thank you!

You provide the values? So, "all values" minus "selected values" equals?

Hi
In an ASP.NET page I am generating buttons dynamically in a table, like this:
Button lmButCls = new Button();
lmButCls.Click += new EventHandler(EditUser);
lmButCls.ID = dbDataReader["LOGONNAME"].ToString();
lmButCls.Text = dbDataReader["LOGONNAME"].ToString();
newCell.Controls.Add(lmButCls);
My eventhandler:
public void EditUser(object sender, EventArgs e)
{
to do code
}
The buttons shows up, but when clicking the "EditUser" nothing happens.
Anybody with an idea to solve this problem?
Best regards, Brian

You're probably not recreating the controls when the page posts back; or you're not recreating them early enough.

Put the appropriate Using statement at the top of the class module and make sure you have included a reference to the appropriate assembly
|
|
|
|
|
Ya I had add all references for it!
|
|
|
|
|
Look at the error message:
The type or Namespace name "Email" could not be found
It's pretty explicit!
The compiler does not know what the Email class is: it hasn't got one for you to use. Either you haven't added a reference to the assembly containing the class to your project, and a using statement at the top of the file to the namespace the class is in; or just the using statement is missing; or you do not have a class called Email at all.
Hover the mouse over the word "Email" and a little blue bar will appear at the beginning. Hover the mouse over that and a drop down will open suggesting ways to fix it.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

Nobody else caught this, but why are you using "dynamic"? It's not for the use case what you're using it. That line should read:
Email email = new Email("ChngPasswordEmail");
Dynamic treats your object as an Object type, removes all static checks at compile time, and slows down the code a bit due to having to resolve method calls at runtime. It also makes it harder to write the code and debug it. It should be rare that you have to use the dynamic type.

I need some help getting this to work. I am trying to read from an XML file that is called "user.config" and is located in "C:\Windows\SysWOW64\config\systemprofile\AppData\Local\MyAppName\user.config". each of the values are Base64 Encrypted (which is nested with more xml). My goal is to be able to read each value independently and store as a variable for later use and to append into textbox1 so that a summary of the settings can be displayed.
Sample XML:

Deserialize the file into a class (paste special xml as class) if you don't want to parse (e.g. XElement):
[System.Xml.Serialization.XmlTypeAttribute( AnonymousType = true )]
[System.Xml.Serialization.XmlRootAttribute( Namespace = "", IsNullable = false )]
public partial class configuration {
<pre>
private configurationUserSettings userSettingsField;
public configurationUserSettings userSettings {
get {
return this.userSettingsField;
}
set {
this.userSettingsField = value;
}
}
}
/// <remarks>
[System.Xml.Serialization.XmlTypeAttribute( AnonymousType = true )]
public partial class configurationUserSettings {
private configurationUserSettingsSetting[] appCentralAppServiceCorePropertiesSettingsField;
[System.Xml.Serialization.XmlArrayAttribute( "AppCentral.App.Service.Core.Properties.Settings" )]
[System.Xml.Serialization.XmlArrayItemAttribute( "setting", IsNullable = false )]
public configurationUserSettingsSetting[] AppCentralAppServiceCorePropertiesSettings {
get {
return this.appCentralAppServiceCorePropertiesSettingsField;
}
set {
this.appCentralAppServiceCorePropertiesSettingsField = value;
}
}
}
/// <remarks>
[System.Xml.Serialization.XmlTypeAttribute( AnonymousType = true )]
public partial class configurationUserSettingsSetting {
private string valueField;
private string nameField;
private string serializeAsField;
/// <remarks>
public string value {
get {
return this.valueField;
}
set {
this.valueField = value;
}
}
/// <remarks>
[System.Xml.Serialization.XmlAttributeAttribute()]
public string name {
get {
return this.nameField;
}
set {
this.nameField = value;
}
}
/// <remarks>

Thank you. I will give this a try. Is the top one the method and the other 2 below it classes i need to create? Once i am able to read the <value> nodes from the XML it should be much easier after that to decode the base64 and output.
|
|
|
|

"configuration" is the "root"; the others are members.
It's what "Visual Studio" interprets from the XML using paste special.
You should study and understand it; then use it.

last question. what would the method call look like? can i still use "XDocument doc = XDocument.load(FullFilePath)" to load the file?
<pre lang="c#">public string XMLStrings()
{
XDocument doc = XDocument.Load(@"C:\user.config");
}
</pre>

Can you give me an example? im attempting to use it in the same context as that link you provided but that isn't working.
|
|
|
|

All that's left is for me "to do it for you".
Not happening.

sorry, im not looking for you to write it for me. This code is for my own person application i am developing as i learn on my own. I am trying to self teach myself C#. I am not working on this for a school or business project.
I am reading over the class and trying to figure out how to include this in my method. Here is what i have so far. Can you at least show me where i might be going wrong? im trying to figure out how to use the variable i to link it to the class and grab the data. I haven't experimented much with custom built classes yet. i used the link you sent me as a template.
public void XMLStrings(string filename)
{
XmlSerializer serializer = new
XmlSerializer(typeof(XMLClass));
FileStream fs = new FileStream(filename, FileMode.Open);
XmlReader reader = XmlReader.Create(fs);
XMLClass i;
i = (XMLClass)serializer.Deserialize(reader);
fs.Close();
textBox1.AppendText(
i.something1 + "\t" +
i.something2 + "\t" +
i.something3);
}
