The easiest is to check for new line characters.
Some binary may contains the newline character(s), in that case you will have to analyze the line a bit more. Obviously a very long line hints to binary.
Also check for control characters, those from 0 to 31 (i think), with a few exceptions of course.
Good luck

hm..not sure if it's worth the effort.
say you want replace "mystring1" with "mystring2". There would be no match in any of your binary files, wouldn't?
Or is it more a performance issue?

Not really, binary file can contain that series of text, no?

Hi,
I have a COM object that accept an array of integer.
HRESULT __stdcall CTestCOM::setValues(int* arr, int arrSize)
{
for(int i=0; i<arrSize; i++)
{
MyDebugTextOut("C:\\Temp\\TestCOM.txt", "arr[%d] = %d\n", i, arr[i]);
}
}
In my C# code:
int[] arrTest = new int[5];
for(int i=0; i<5; i++)
{
arrTest[i] = i;
}
TestCOM testCom = new TestCOM();
testCOM.setValues(ref arrTest[0]);
The result of my text out in x86 is correct:
arr[0] = 0
arr[1] = 1
arr[2] = 2
arr[3] = 3
arr[4] = 4
arr[5] = 5
But in my x64, it is wrong:
arr[0] = 0
arr[1] = -321451
arr[2] = -14537642
arr[3] = 0
arr[4] = 0
arr[5] = 0
I've checked the address of the array, in x86, it pass a same address from C# to COM object. But in x64, address of the array in the COM object is different from C# array.
Any idea why? If yes, is it possible to fix it?
Thanks

Although I do not know COM interop, there are a lot of things wrong here...

Why are you passing the reference to the first element in? A .NET array isn't just a int buffer! If you fixed it, then maybe you can use it. (does COM not require you to pass the length parameter too?)
RYU^^ wrote: arr[5] = 5
Your array length is only 5, so how can you read the 6th element?

Hi Leppie,
Thanks for the reply. The reason I pass the first element address because I want to manipulate the value in my COM object. It works fantastically in x86, but doesn't work in x64.
leppie wrote: (does COM not require you to pass the length parameter too?)
You were right, the length of the array must be passed in to the COM object. But in my case (not in this example), it is actually determine by another attribute that is set previously.

Uppppsss... you were right again. It should be new int[6]. Sorry...

Before I begin, I'm a C#/.NET newbie. I'm completely familiar with C/C++ and using VS in that context, but you can probably expect me to have made very trivial errors.
Anyway...
I'm trying to implement a spell check into a tool I'm helping to develop -- I suppose the easiest way to do this would be to use the spell check from Word, so I don't have to duplicate any of its functionality.
I'm working in C#, but the article on this site for a VB.net version (http://www.codeproject.com/KB/office/SpellCheckUsingWord.aspx) helped to walk me through writing it up.
However, there are catches! Apparently, all of the tutorials I've checked out are using a different version of Office (11 instead of 12) which keeps me from compiling.
Here's my relevant code...
ApplicationClass WordApp = new ApplicationClass();
DocumentClass WordDoc = WordApp.Documents.Add();
WordApp.Visible = false;
String OldClipboardText = Clipboard.GetText();
Clipboard.SetDataObject(textBox1.Text);
WordDoc.Content.Paste();
WordDoc.Activate();
WordDoc.CheckSpelling();
WordDoc.Content.Copy();
if (Clipboard.GetDataObject.GetDataPresent(DataFormats.Text))
{
textBox1.Text = CType(Clipboard.GetDataObject.GetData(DataFormats.Text), String);
}
WordDoc.Saved = true;
WordDoc.Close();
WordApp.Quit();
Clipboard.SetDataObject(OldClipboardText);
and here's the compilation log:

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
Why is VS crying over the number of arguments? All of the MSDN documentation I've read says that the arguments I leave out are optional. I'm rather exasperated, having been Googling this for a while, either to find a less frustrating method of implementing this (and preferably less hackish than copying and pasting it behind the scenes) or to see if somebody else that figured out what's up with the function parameters, but no luck.
Thanks in advance.

Alex, one thing I'd say is, are you sure you need to use the full blown Word spell checker? There are plenty of free, more lightweight alternatives out there. (I just searched for C# spell checker and got some articles).
Also, are you aware that WPF (the new UI toolkit part of .NET 3 and up) has text boxes and rich text boxes with built in spell checker?
Now, if none of that dissuades you from using Word's spellchecking, here are my thoughts:
-a couple of the errors are mistranslations from VB.NET, such as the CType one and possibly the "string is a type but is used like a variable". Are you aware there's a C# article showing how to use Word's spellcheck on CodeProject?
-the rest of the compiler errors may be differences between VB.NET and C#, where VB.NET allows for "optional" params, C# doesn't. For cases like this, try passing in the default value (such as null for objects, 0 for ints, false for bools, etc.).
Another thing to check out if you're set on Word's spellchecking is Microsoft's "Visual Studio Tools for Office" set of APIs. Microsoft built some interop dlls and tools for easier interop with Word from C#. Search MSDN for more info.

You have to rename them through the file system, e.g. through Windows Explorer.

Hey everyone. I've been scrounging around on here and finally figured out how to export the data to an excel document from my dataset, the only problem i'm having now is I can't add a new worksheet. I have a data set with that i've filled with three different tables and I need each table to go into a seperate worksheet (so the marketing guys can then use that for their photoshop stuff.) what I have so far is just adding different headers on the same sheet...
Excel.ApplicationClass excel = new Excel.ApplicationClass();
excel.Application.Workbooks.Add(true);
System.Data.DataTable table = data1.Tables["table1"];
int Collindex = 0;
int rowIndex = 2;
excel.Cells[1, 1] = "table 1";
foreach (System.Data.DataColumn col in table.Columns)
{
Collindex ++;
excel.Cells[2, Collindex] = col.ColumnName;
}
foreach (DataRow row in table.Rows)
{
rowIndex++;
progbar2.PerformStep();
progbar2.Refresh();
Collindex = 0;
foreach (DataColumn col in table.Columns)
{
Collindex ++;
excel.Cells[rowIndex + 1, Collindex] = row[col.ColumnName];
}
}
progbar1.PerformStep();
progbar1.Refresh();
table.Clear();
table = data1.Tables["table2"];
progbar2.Value = 0;
progbar2.Refresh();
progbar2.Maximum = data1.Tables["table2"].Rows.Count;
progbar2.Refresh();
rowIndex = rowIndex + 3;
excel.Cells[rowIndex, 1] = "table 2";
foreach (DataRow row in table.Rows)
{
rowIndex++;
progbar2.PerformStep();
progbar2.Refresh();
Collindex = 0;
foreach (DataColumn col in table.Columns)
{
Collindex++;
excel.Cells[rowIndex + 1, Collindex] = row[col.ColumnName];
}
}
progbar1.PerformStep();
progbar1.Refresh();
table.Clear();
table = data1.Tables["table3"];
progbar2.Value = 0;
progbar2.Refresh();
progbar2.Maximum = data1.Tables["table3"].Rows.Count;
progbar2.Refresh();
label7.Text = "Safety Cover Pricing";
label7.Refresh();
rowIndex = rowIndex + 3;
excel.Cells[rowIndex, 1] = "table3";
foreach (DataRow row in table.Rows)
{
rowIndex++;
progbar2.PerformStep();
progbar2.Refresh();
Collindex = 0;
foreach (DataColumn col in table.Columns)
{
Collindex++;
excel.Cells[rowIndex + 1, Collindex] = row[col.ColumnName];
}
}
I've played around with excel.application.worksheets.add() but can't get the syntax correct (if that's even the right object I want to be working with. I just need a point in the right direction.
Thank you!

Well, I've seen this before and tried it but the compiler yells at me saying missing isn't found in the current context. I even tried replacing globals.thisworkbook with excel.application.workbook but it still gave me the same problem. What I don't understand is why we can't just add a worksheet without passing any parameters.
|
|
|
|
|
workbook.Worksheets.Add(Missing.Value, Missing.Value, Missing.Value, Missing.Value);
The MS example was incomplete. The line above works.

I am trying to make an application, and I want to have a menu at the top, and then when i click on lets say Start on the menu bar, it changes the window, so that it still has the menu at the top but everything else has changes. I dun want to remake the window, and i dun want to have all of the things in code and just change the visibility.
here is what i thought would work, creating UserControls and then change the UserControl.
UserControl replace = new CreatePage();
this.C = replace;
CreatePage is a page that asks for a bunch of items. Please let me know what i should do.
I do not get any sort of error, but nothing actually changes. Thanks for everyone helps

Throw your controls on a panel of some sort. When you want to hide them, hide the panel. Voila it's all gone.
WPF forum is over there[^], by the way.

thanks for the advice, i put it in the C# section because the coding i had was C#.
Still looking for maybe a better solution tho

I'm not sure I follow, but you should have some type of control (grid, canvas, etc) for your main window. Then based on the event (start menu click, for instance), add or remove your user controls.
For example: You have a Grid named MyGrid in your window, which has multiple row definitions and you want to add a user control (your replace control):
CreatePage replace = new CreatePage();
replace.SetValue(Grid.RowProperty, 2);
this.MyGrid.Children.Add(replace);

thanks your comments were helpfull, but here is my main predicament. I want to have a starting window. if you click a button it will show you something different. this different thing is called, and is a UserControl.
How it is Called:
void New_Click(object sender, RoutedEventArgs e)
{
this.Grid.Children.Remove(UC);
this.Grid.Children.Add(create);
}
create was already initialized up top, and it has its own xaml and code behind file.
So now the window is populated with all the original information but instead of UC in the main text area, i have put this new createplayer UserControl. Now its going to fill out some information in a form. then you would hit a submit button. I then want it to go back so that UC is the UserControl not create. Everything you entered into this form, is then saved into a class.
What is the best way to do this? Let me know if anything is unclear

I'm currently developing a desktop application in C# that will be installed on a network drive.
This will cause FileIOPermission error because the users don't have the Full Trust on the Intranet Zone.
I don't want that the user should have to install the SDK to change the settings and wonder then if it possible to change the settings to Full Trust thrue the application?

Phrone,
I'd think this wouldn't be possible, else you could run any code you want on a persons computer.
Also, you dont need to do this. See link.
