I'm trying to access functions of a C# interface from an extened SP written in C++ (Unmanaged) and I'm having problems retrieving the complete string upon reception in the interface.
I am using the MarshalAs attrib but for some reason, I cannot get this to work correctly...
Here is waht I'm doing...
Extended stored proc C++
__int64 nReturnCode;
char Text[20] = ".Net Rules";
pInterface->raw_Command((BSTR)Text, &nReturnCode);
C# interface...
public interface IMyInterface
{
long Command([In, MarshalAs(UnmanagedType.LPWStr)] string strText)
//could be the type that I'm using, but I have tried many and stil cannot get this to work...
};
public clase MyClass : IMyInterface
{
public long Command(string strText)
{
MessageBox.Show(strText);
return 0;
}
};
Messagebox: "????????s"
Please help me out with this one
Cheers

First, I know nothing about ASP coding or anything like that. What I do know, I need a better way to organize my photos. I have tried many programs, all cumbersome and not friendly to use.
So with that, I am looking at installing this program for my photo album pages.
What I need, is to hire someone to set it all up. I can do 50% up front (upon ref.), another 25% when you show me it works. The last 25% paid when done.
You will need to show/instruct me on how to upload the photos and how the program works.
My site is desertdrifter.com. It is hosted by hostsave.com. If need be, I will change host providers to get this up and running.
Serious inquires only.
I can be reached at jbriggs@desertdrifter.com.

I prepare my application for L10N and use System.Resources.ResourceManager.GetString() to retrieve string resources.
Works great, but does not include any compile-time checking: The argument to GetString() is an alphanumeric string identifier. A typo in this ID, and the application will still compile. Only when the string is needed (probably to display crucial details of that critical error), if cannot be found and GetString() returns null.
This is not good. Does anybody know of any tools or preferences that validate the presence of required string resources at compile-time?
TIA,
Bernd

I have a parent form that I have set the IsMdiContainer property to true. I have 2 other forms that I want to show up inside of the parent form. The first form called frmAnchor will be docked to the top of the parent form. The second form called frmCollect I want to fill the remaining area of the parent form, so I set the DockStyle to fill. When I run the program it looks OK, however once I click on the top form (frmAnchor) it shifts the bottom form (frmCollect) up to fill the entire area (even the area under frmAnchor). So, it is almost like using DockStyle.Fill on the bottom form doesn't know about the top form and fills underneath it.
Here is the code I use to show the child forms. This code is inside the parent form. Any ideas on how to keep the bottom form from shifting up when clicking on the top form?
frmAnchor newMDIChild = new frmAnchor();
// Set the Parent Form of the Child window.
newMDIChild.MdiParent = this;
newMDIChild.Dock = DockStyle.Top;
newMDIChild.Show();
frmCollect newMDIChild2 = new frmCollect();
// Set the Parent Form of the Child window.
newMDIChild2.MdiParent = this;
newMDIChild2.Dock = DockStyle.Fill;
newMDIChild2.Show();

I want to create a windows application like the project property page of CSharp project in a solution
(right click project in a solution, you will get project property pages).
when you click "common properties" you will get list bot control on the right panel,
when you click "Configuration properties" you will get data grid control on the right panel.
I want to do the similar things. My question is how to create different controls on the same positions?
thanks a lot!

I am new at C#, and I would really appreciate it if someone could write me up a small example app or equivalent item. Thanks so much you guys are lifesavers!
My Code so far:

Hi All,
Am new to the c# world.I have been trying to find an example or some reference which would help me bind an object directly to a DataGrid, but i havent come across one. All the examples bind DataSets which have data from databases. Is it possible to directly bind an object to a DataGrid, without me having to make an intermediate DataSet and write the read/write funtionality myself.
Any help appreciated.
Thanks

Nope,You need DataSet when you work with DataGrid.

No sig. available now.

You can also bind a datagrid to a Collection or any object that implements the IList or IListSource Interface.

Hi,
Thanks.But my obeject is more of a graph and i have arays everywhere. Does that mean that i will have to change everything into collections, and implement all their methods. that will surely suck.
I have a stupid doubt. Could i just serialize the whole obejct into an xml strem( SoapFormatter) and then deserialize it into a Dataset, and bind that to a DataGrid.
Thanks

I have to port a MFC app to .NET. The main window is dialog with a big tabcontrol and many tab pages. In C++ every tab page was a dialog, so it has a default push button, in C# only the main form has an accept button. How could I "press" different buttons depending on the active tab page on Enter pressed? The only way I could see is to handle the key(up|down) event, verify if it is Enter (how?) and do something further, but must be something easier 
The other problem: I want to set the focus on one tab page component when the page is shown, and keep the current focus no matter how the pages are changed (I mean when switch back). The control.Focus() in the Load method does not work, when should I call Focus?
Thanks

First problem:
What I have done is, I have put a button "OK" or "Apply" on a form, not on a Tabcontrol but just below the tabcontrol. and made it the acccept button.  i was checking that what is the selected control on the tab thru my program. but i had only 2 tabs and was easy to track down.
|
|
|
|
|
I end up with something similar: I put an accept button on the main form and "hide" it (size 1x1, flat, *color = main background) and this "invisible" button will route the Enter according to the active tab page. I can not use a single, normal button for all pages because the actions are quite different (enter, delete, view, load, ...) so the button's name would be a real problem.
This thing works but MUST be some other way

Hi there,
Having got fed up of constantly picking track lists from large mp3 collections or using crummy auto playlist selectors I was wondering if I could write something better, the only problem is I don't know how to go about getting an mp3's characteristics like it's tempo or pitch etc.
Does anyone have any samples/info on this type of thing?
a million fang-queues in advance for any titbits you can offer

If I have this kind of question, I use Google and do a little searching. After a couple of minutes I found this on CodeProject itself

Thanks, I did see that article already however and it is not the ID tags that I'm looking to read but the actual music itself.
I did do quite a bit of rooting around google before I asked but so far I've not found any info on calculating the bmp/tempo of a piece of music which is what I'm looking for.

Since the MP3 music format is copyrighted, I would guess that you'd have to purchase a license to the format. That's why you're not getting any hits.

Ahh I see. Thanks for the tip
Does anyone know how to obtain BMP/tempo and pitch information from an unlicenced or GPL music format such as ogg or is it possible to convert an mp3 to another format for processing which avoids these pesky legal pitfalls?
I'm off to copyright the sound of a telephone ringing then go on a litigation rampage!

I have an XML file which has a depth of 4 elements:
-----------------------------------------------
<?xml version="1.0" encoding="utf-8" ?>
<MutualFunds>
..<Fund>
....<FundName>Altamira Fund</FundName>
........<Holdings>
............<Company>
..................<CompanyName>The Procter & Gamble Company</CompanyName>
..................<Symbol>PG</Symbol>
..................<Shares>13500</Shares>
............</Company>
........</Holdings>
....</FundName>
..</Fund>
..<Fund>
....<FundName>Lynch Fund</FundName>
........<Holdings>
............<Company>
..................<CompanyName>Gerber Foods</CompanyName>
..................<Symbol>GF</Symbol>
..................<Shares>13500</Shares>
............</Company>
........</Holdings>
....</FundName>
..</Fund>
</MutualFunds>
-----------------------------------------------
Im trying to read in this XML file and have it parsed so that the contents under <FundName> (Altamira Fund and Lynch Fund) appear in a combobox while its respective <Company>s under <Holdings> are preserved in an ArrayList so that when I select the Altamira Fund from the combobox its respective company's will appear in a ListView.
I've tried tackling this simple problem with:
=[1]=
DataSet ds = new DataSet("MyData");
ds.ReadXml("Holdings.xml");
DataTable t = ds.Tables["Fund"];
=======
=[2]=
XmlTextReader reader = new XmlTextReader("Holdings.xml");
While (!(reader.MoveToContent() == XmlNodeType.Element && reader.Name == "FundName"))
{
reader.ReadString();
}
======
In [1] i tried getting the DataSet to return back a the <Fund> element hoping that it would belong to the Altamira Fund group but it seems the Lynch Fund name was apart of this table. In [2] Im trying to iterate thru the nodes until i get to what I want then begin storing what i need then moving on to the next element. When a </Fund> is reached Ill know the next <Fund> is coming up.
Ideally i want to ask the XML reader to simply return back the <Fund> group of the "Altamira Fund" (which will contain the <FundName>Altamira Fund</FundName>, <Holdings>, and respective <Company> elements). It shouldnt include the other <Fund> in any way. Once I've processed this first fund then i can move on to the next with its respective childern. What Im see from DataSets is its clumping all similar tag contents together, so <Company>'s in both <Fund>s are being placed together. When it comes time to create my ComboBox with respective Company's the presented information will be incorrect. As for the MoveToContent iteration, it seems acceptable but a bit dirty.
Do i "need" to create an XML Schema or use DataRelations in any way?
Thanks.

The easy was is adding a registry entry documented here on MSDN that points to a file containing your script code.
Here's an example of both that I wrote long ago
Save this in borders.inf:
[Version]
Signature="$Chicago$"
Provider=%BCDEV%
[DefaultInstall]
CopyFiles=Files
AddReg=Reg
[DefaultUninstall]
DelFiles=Files
DelReg=Reg
[Files]
%BASENAME%.htm
%BASENAME%.inf
[Reg]
HKCU,%IKEY%,,,"%10%\%SUBDIR%\%BASENAME%.htm"
HKCU,%IKEY%,contexts,1,%CONTEXTS%
HKLM,%UKEY%
HKLM,%UKEY%,DisplayName,,"%TOOLTITLE%"
HKLM,%UKEY%,UninstallString,,"%UCMD% %10%\%SUBDIR%\%BASENAME%.inf"
[DestinationDirs]
DefaultDestDir=10,%SUBDIR%
[Strings]
TOOLTITLE=IE4 Addon - Show Table Borders
BASENAME=borders
CONTEXTS=1
IKEY=Software\Microsoft\Internet Explorer\MenuExt\Show &Table Borders
UKEY=Software\Microsoft\Windows\CurrentVersion\Uninstall\ShowTableBorders
SUBDIR=web
UCMD="rundll32 syssetup.dll,SetupInfObjectInstallAction DefaultUninstall 132"
BCDEV=Blake Coverett Development
And this in borders.htm
<script language=javascript defer>
var tables = external.menuArguments.document.all.tags("table");
if (tables != null) {
for (i = 0; i < tables.length; i++)
{
tables[i].borderColor = "red";
tables[i].border = 1
}
}
</script>
Right click on borders.inf and choose Install. The INF file was meant to be reusable by just changing the strings at the bottom, feel free to reuse it.
