Hello all,
I'm having some headache with my project references.
First off all, I have a common library which uses 3rd party .NET librarys. Now, the problem is that all these 3rd party dll's come from one program that needs to be installed on the system for my application to work. But still, vs2010 copys the dll's into it's output directory and uses those copys instead of the dll's located in the program folder of the 3rd party program. (Are you with me, I know my english isn't top of the notch) How can I prevent this, so that vs2010 doesn't copys those dll's again, and that my app will use the original dll's?
Is it possible?
The next problem I have, is that in my application, I use a usercontrol from my library that uses a 3rd party dll. And for some reason I really need to add that 3rd party dll to my application references allthough my library already references that 3rd party dll. Can I change this behaviour? So that referenced dll's from my library don't need to be referenced in my application itself?
I hope that my questions are clear,
Thanks in advance!

I was tasked in my schooling with adding security features to a calculator code we wrote for a previous project. I have never used security features before and have not the first idea how to incorporate them in my project. We apparently have to add them to our functions (plus, minus, multiply, divide). I'm not asking for anyone to do the work for me but I could use help with what exactly needs to be done.
The following is an example of the code for the button that divides:
Private Sub Button4_Click(sender As Object, e As EventArgs) Handles divNum.Click
ansBox.Text = (Integer.Parse(numBox1.Text) / Integer.Parse(numBox2.Text)).ToString()
End Sub
If more of the program is needed or anything just let me know. Any help would be amazing!

What do you mean by "security features"?
"These people looked deep within my soul and assigned me a number based on the order in which I joined."
- Homer

Here is my teachers exact wording of the assignment.
The GUI interface for your calculator now needs additional functions. To add security functions address the following in your Visual Studio file:
Program at least one of the functions (add, subtract, multiple or divide) in your calculator program to include a security feature.
An example of a security feature is to declare a variable as "private" as opposed to "public" (conduct some independent research if necessary to refresh on these topics).
|
|
|
|
|
Other than being in VB instead of c# I don't see anything to change in the code you've shown. 
Seriously:
From the wording, it looks like the issue is the accessibility of the various variables and methods in the implementation of your program. Make sure everything has the most restrictive accessibility (public/internal/protected/private) that still allows it to function correctly. Then look at things that aren't private and think about how you could redesign your code to reduce their "exposure".
I'd suggest you avoid modifying the accessibility of any code generated by the designer, lest you confuse the designer.

As Matt says, this has nothing to do with security; it's a pity your teacher does not understand that.

He left this piece of python code as an example for the assignment but idk where in the code it has the security feature. From everything I have found all of my code says private on it so if that's what he wants it should have been already done lol

Well I know nothing about python; and you posted this question in the Visual Studio forum. However, and more relevant, there is nothing you can do to a calculator to make it secure, even if we really understood what that is supposed to mean. Go back and talk to your teacher and get a better explanation of what problem you are supposed to be addressing.

This is a visual basic calculator code he also gave as an example:
Public Class Form1
Private Sub calculateBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles calculateBtn.Click
Dim number1 As Double
Dim number2 As Double
Dim answer As Double
If input1TextBox.Text = "" OrElse input2TextBox.Text = "" Then
MessageBox.Show("Please Enter a Number")
ElseIf additionRb.Checked = False And subtractRb.Checked = False And multiplyRb.Checked = False And divideRb.Checked = False Then
MessageBox.Show("Please Choose an Operation")
Else
number1 = Double.Parse(input1TextBox.Text)
number2 = Double.Parse(input2TextBox.Text)
If additionRb.Checked = True Then
answer = number1 + number2
answerLbl.Text = answer.ToString()
ElseIf subtractRb.Checked = True Then
answer = number1 - number2
answerLbl.Text = answer.ToString()
ElseIf multiplyRb.Checked = True Then
If number1 = 0 OrElse number2 = 0 Then
answerLbl.Text = "0"
Else
answer = number1 * number2
answerLbl.Text = answer.ToString()
End If
ElseIf divideRb.Checked = True Then
If number1 = 0 Then
answerLbl.Text = "0"
ElseIf number2 = 0 Then
answerLbl.Text = "Cannot Divide by Zero"
Else
answer = number1 / number2
answerLbl.Text = answer.ToString()
End If
End If
End If
End Sub

I am just learning how to use the program. When I saved my project and closed out it left me three files.
Calculator.Designer.vb
Calculator (resx)
calculator.vb
No matter which of these files I open I have no way of opening the project and trying to compile them so I can see if my program works.
I would also like to know if there is anyway to turn the GUI interface back on when i reopen a project.
Thank you for any help you can give!

Start Visual Studio and load the solution or project, not individual files. And press F5 to run the program. See also the Visual Studio help or get a copy of a book on VB.NET which will explain all the different options.

I'm trying to create a custom temple, and I have some files in the solution that need to have the project name as their name. I have the following:
<ProjectItem ... TargetFileName="$safeprojectname$.dll.config">test.dll.config</ProjectItem>
<ProjectItem ... TargetFileName="$safeprojectname$.xml">test.xml</ProjectItem>
But when I create a new project with the template, I get a Visual Studio error saying it can't copy the file because it can't find it.
Anybody got any clues for me?
EDIT ========================
BTW, I also tried using $projectname$ instead of $safeprojectname$, and it doesn't matter where I put either one - I still get the error.
Lastly, I tried using "xyz" instead of $projectname$, and that gave me the same error.
This is STUPID.

I'm not sure what language template or what file the above belongs in, but should you not be using $safeprojectname$ rather than test in the text portions of the above statements?

I tried that too, but according tot he MSDN site, I'm supposed to use the TargetFileName attribute.

Maybe it's choking on the fact that they're named "test". Is it finding all of the other files ok?

That was a simple replacement because I was too damn lazy to type the actual entire file name.

Based on this (probably what you are looking at), you also have to set ReplaceParameters to true:
<ProjectItem ... ReplaceParameters="true" TargetFileName="$safeprojectname$.xml">test.xml</ProjectItem>

Well, nevermind I guess. I just tried this and I get the same error:
Microsoft Visual Studio: Unable to copy the file 'Go.cs' from the project template to the project.
Cannot find file "C:\Users\AspDotNetDev\Local\Temp\jsdgjlkgjlk.ljksd\Temp\Go.cs".
According to this, it may be a Visual Studio bug. However, if it is, it exists in both 2010 and 2012 (I tried both).

When I try this the error message is saying it can't find the original file, e.g. test.cs, in the temporary directory used for template expansion.
After monitoring the temp folder with a filesystem watcher I can see the correctly renamed file, not the original file. So far so good as the file was supposed to be renamed. The issue is why after having renamed the file, does VS then stupidly look for the original filename.
VS appears to be using the project file to decide which files it needs to copy from the temp directory to the final location. The fix is to use replaceable parameters in the project file for any renamed files.
e.g. change
<Compile Include="test.cs" />
to
<Compile Include="$safeprojectname$.cs" />
I use the word fix rather than solution as now the modified project file is only good after the parameters have been replaced by template expansion. If you try and open it directly, VS will look for a file named $safeprojectname$.cs.
Damn tricky things, these templates!

I got it working! The important missing step was to modify the .csproj file itself to account for the new dynamic filename. In my test, this was the only thing I really needed to change:

Hi, I 'm developing (trying actually) a desktop application that works well only if the word "PERIOD" is located in the cell A14(inside an excel file). But instead of that, I'd like to make it work if the word "PERIOD" is found no matter what cell it is in, provided it is inside the column 'A'.
That's the problem, I don't know how to search a certain word inside a column and get its cell(the 'row part' actually).
In other words I'm looking for this code: "If a cell inside column A contains "PERIOD", get the number of row".
Any ideas?
Thanks in advance.

This has nothing to do with Visual Studio, and since you have not mentioned what programming language you are using, or how you are accessing the Excel file, it is difficult to make a useful suggestion.

I want to make a directory structure for my project, like:
project1\header
\source
\Lib
\resource
etc..
On my disk, I created the folders. but I don't know how to import the structure to my visual studio virtual groups.
I mean, when I moved .h files to \header folder, visual studio could not found .h files then.
Is there a method to let visual studio work with physical directory structures?

Yes it is possible but once you have the files in place you then need to add them to the project in Solution Explorer, from their source locations.

I tried, but the .cpp files can't find .h files.
#include "stdafx.h" for example, even I changed it to:
#include "Header/stdafx.h"
IDE gives:
unexpected end of file while looking for precompiled header. Did you forget to add '#include "stdafx.h"' to your source?
|
|
|
|
|
- Do a Clean of your project and delete all the Debug and Release folders.
- Make sure that you have added all the files into the project correctly.
- Check that all
#include statements have the correct path prefix where necessary.
- Rebuild the project and correct any errors.
- Repeat as necessary.

I changed the project directory structure like the following:

project1\project1.vcproj; project1.sln
Now I got error message:
fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add '#include "stdafx.h"' to your source?
In StdAfx.cpp, only one statement:
#include "..\Header\stdafx.h"
Could you give me some tip?

I already told you what to do in my previous response. However, given the fact that you do not really seem to understand how this works, I would suggest you forget this idea and stick with the standard project structure as created by Visual Studio.

I understand your previous post. and I created a test project, sure, it works.
But, the project I am working with, it seems remove old, add new location, clean, IDE still give error messages.
This is a WinCE template project, supplied by one company, will ask them how to solve it.
Thank you for your help

The error message indicates that the project has not been cleaned properly, as Visual Studio thinks that there should be a precompiled header somewhere. Clean and rebuild should fix this. Since this project is not your own it would make more sense to leave it as is.

Which edition of Visual Studio? You'll need Ultimate to create code maps. Either Premium or Professional will let you open existing maps, make limited edits, and navigate code.

If you have Ultimate, you can right-click a solution, project, or code file in the Solution Explorer and pick "Show on Code Map".
If you don't see this option, you don't have Ultimate.

Hi,
I am a beginner for Metro app development and trying to use the keydown event but not the keyup event with a text box element on the XAML. I have created two key event functions (up and down) from the text box, which are the below. The problem is the keydown function works only when the key is up but not down. If I hold the key press down, the event does not come out until the key up, which is the same as the keyup function.
I am working to get keyboard input from the touch softkeyboard. For example, after invoking the touch keyboard with the text box element, I like to play a unique sound only when a key (e.g., 'Q' or 'K') is pressed.
Anyone knows how to fix this problem? I also appreciate that you can help me know the alternative way with an example source code. Thank you a lot in advance.
MainPage::OnKeyUp(Platform::Object^ sender, Windows::UI::Xaml::Input::KeyRoutedEventArgs^ e)
{
if((int)e->Key == 112) // F1 key
{
errorText->Text = "F1 Key up";
}
}
MainPage::OnKeyDown(Platform::Object^ sender, Windows::UI::Xaml::Input::KeyRoutedEventArgs^ e)
{
if((int)e->Key == 112) // F1 key
{
errorText->Text = "F1 Key down";
}
}
I just found that only space key, backspace and enter key are working for keydown but all other keys are sending the key down event when the key is released on the touch keyboard. So my question must be rephrased to how to make all other keys send the keydown event on the Keydown api? or the other apis?
Thank you.

(SOLVED) I have played with this, but I am missing the obvious. Can I borrow your brains again? (I dislike working alone.)
I make a selection in the datagridview. This selection is now processed in the make list handle. I bold the first column's text for identity on the datagridview. I want to keep the value from the cell in a list. I get out of range and null exceptions.
At this point, I do not have the cleanest code as I am working on operational aspects of the grid. So, below the instruction to bold the selected, I am counting the bolded (which works fine) for a count value on the form to be displayed, but I cannot add the "job number" to my list. And before you ask, yes the job number is a string. I checked that first!
Original declaration is ...
dim selectedJobNo as list(of string)
Private Sub MakeListToolStrip_Click_1(sender As Object, e As EventArgs) Handles MakeListToolStrip.Click
Dim f As Font = New Font(JobsDataGridView.Font, FontStyle.Bold)
For selectrow = 0 To JobsDataGridView.SelectedRows.Count - 1
JobsDataGridView.SelectedRows(selectrow).Cells(0).Style.Font = f
Next
Dim i As Integer = 0
Dim count As Integer = 0
selectedJobNo = New List(Of String)
For i = 0 To JobsDataGridView.Rows.Count - 1
If JobsDataGridView.Rows(i).Cells(0).InheritedStyle.Font.Bold Then
count = count + 1
selectedJobNo.Add(JobsDataGridView.SelectedRows(i).Cells(0).Value.ToString)
MsgBox(selectedJobNo.Count)
End If
Next
JobSelectedToolStrip.Text = count
'remove highlight selection and deselect any row highlight
Me.JobsDataGridView.SelectionMode = DataGridViewSelectionMode.CellSelect
End Sub
Solution:
I am leaving this post in case someone tries a similar method. However, I switched to a collection! I don't know why I didn't think of this. I am so very accustomed to just using a list.
Here is what I did ...
1. When item selected in the DGV. I bolded the index/reference cell only. I add to the collection.
2. When removing an item from the custom selected list, I un-bold the index/reference cell. I remove from the collection.
3. When they switch between sorts, I run through the collection to bold the index/reference cells (because the DGV gets a new datasource selected based on the predefined sorts open/closed/all).
4. On request to print, I run through and add to an unbound datasource which I assign as the base for the dataset that prints the report and exports to excel.
Don't forget to check if the index/reference in the collection exists.
You might wonder why I just don't track the DGVrows? Well, the way that it works, user can select and deselect as many times on as many different sorts as the user would want (which is quite often). I did not want to keep moving these rows in and out and sacrifice any "time". I kept it simple and did not record any selections until the time at which the user decides that they actually want the selection.
Hope that made sense, LOL.
